Screen flicker on external monitor - Dell XPS 13 9350 QHD display

Question: Screen flicker on external monitor - Dell XPS 13 9350 QHD display

When I connect my Dell XPS 13 9350 laptop with QHD display to an external monitor through the DA200 USB-C to HDMI connector the external monitors flicker constantly (laptop is fine-no flickering). Sometimes it works for like an hour then starts to flicker or longer so its not consistent. Below are the troubleshooting steps Dell has walked me through (including sending me a new DA200 part) to no avail:
- Dell has sent me a new DA200 USB C to HDMI part
- They have upgraded the Thunderbolt drivers and all other relevant drivers to latest ones (as of June 15 2016)
- I have tried on different monitors (5-6) and tried different HDMI cables.
Dell doesnt seem to know what to do now. THey have refunded my DA200 part purchase and told me to buy a separate HDMI to USB-C cable to test. If that fails it seems they will replace the motherboard. They say it could be an issue with the external monitors not being compatible with QHD, but this is not documented anywhere (they admit) and I havent heard anyone else having this problem on the internet and surprised every single person using this setup has QHD external monitors. This is an unworkable situation for me as I work in PC labs all day connected to external monitors.
Any advice?

My xps 13 9350 laptop screen is just blank but when I hook up an external monitor it shows everything. I went to my display settings and it doesn't even recognize a second display, for some reason it thinks the external monitor is the main screen. When I click "detect" it doesn't detect a second display.
I have booted in safe mode and everything works on the actual laptop but otherwise it only boots with a an external display.
Any help would be appreciated.

Just received the XPS 13 (9350) last week and I've been having some intermittent black screen flickering that normally occurs in short bursts of 4-5 short black outs within a span of two or three seconds. Tech support updated all the drivers and such, but I'm still experiencing the issues. Has anyone had similar issues and possible solutions?
I looked at previous posts and the screen flickering is not where it actually distorts things on screen, it literally just looks like it flashes on and off. Any help is appreciated!

I have a Dell Inspiron 15 7568 laptop that is less than a week old. I also purchased a Dell HDMI to VGA adapter so that I can use an external monitor with a VGA input as a 2nd screen. 
Whenever I connect to the external monitor my laptop screen, not my external monitor screen, flickers a couple of times a minute. I have checked all the connections of the adapter and VGA port and they seem fine. It appears there is a problem that is encountered when I plug in the external monitor that causes the laptop screen to flicker occasionally. 
If anyone has any suggestions to fix this issue it would be greatly appreciated.
Thank you.

I use a XPS 9350 for about a year now. Its a certified refurbished with core i7, 16 GB and 512GB SSD.
I had an issue with usb C adapter tha has a lan port, HDMI port and usb 3 port. When I detach and reattach the adapter with laptop power on I almost always loose the external monitor (extended desktop mode) display. Display properties showed that cant detect the external display. the external monitor also goes to idle state. I need to turn off / restart laptop several times to get the external display on, sometimes for a whole day it did not come back at all.
I found a work around, when this happens go to display properties and change the "Extended desktop mode" to "Duplicate the display" mode and the apply, the other monitors get back to normal. you can reapply the Extended mode afterwards and it works fine.
I use kwmobile usb c hub.
I hope this post also help someone else. It s pity that a fine laptop has so much issues still to be addressed. (Auto wake up is killing me!!)

I bought an USB-C to HDMI adapter cable to connect my Dell XPS 9350 to an external monitor (Dell U2414H).
I connect my laptop with adapter via USB-C, the HDMI port of adapter with HDMI cable and the HDMI cable with the external monitor. After that, the external monitor detected the laptop but it displays error message like that "There are no signal from your computer. Please press any key to wake up it".
My laptop still running, I also changed mode to duplicate or external screen and update all drivers but nothing change.
I checked the Intel Graphic Setting, it also detected the external monitor.
Please see attached images for more information and help me to fix it.

Im having a problem when i connect my laptop with external display.
My laptop is HP tx2(12" display) with windows vista sp2 and my external display is an LCD tv of Onida(Xaria 22")

When i connect my laptop to the LCD tv, the connection is ok... display comes properly....resolution is also good...
but after some time of using it(either watching videos or even normal browsing) the display flickers and then gets diconnected(with the disconnection sound or tone) and automatically gets connected again.
sometimes after auto re-connection the resolution also gets changed....this is really annoying..

Iv used the help section... they asked me to increase the flicker rate to atleast 75 but my laptop has a max freq of 60hz only. iv also applied max resolution to the screen...but the same thing always happens again..
then i also connected the same lcd tv to my another laptop(hp dv6000, 15.4", vista sp2) and the same problem never comes. even the flicker rate of that laptop is max 60 hz. both have same resolutions also

iv tried all that i cud.... advise please.....

I bought a Dell XPS 13 9350 in December and I wanted to connect it to an external monitor via the thunderbolt port. I bought an type c to hdmi adapter off amazon and it connects. (Actually bought 2 and the problem persists). But occasionally both my screen and laptop will turn black then back on again. This causes my video that i'm playing to either freeze/crash (netflix/youtube) which is SUPER annoying. It goes from occasional to quite often. It's really random.

My drivers are up to date, cable is new and the monitor is new from boxing day. 

Any help is appreciated :)

Dear all,
Wonder if you can help me solve a problem. I have just received an XPS13-9350 from the Outlet last week. It was certified refurbished.
I've tried to connect a VGA monitor to it via a USB-C to HDMI, then HDMI to VGA cable. The HDMI to VGA cable works perfectly on my Inspiron 15. The setup also works if I full power down the XPS13, attach USB-C to HDMI to VGA to monitor, and then boot up. The external monitor then works almost perfectly (with the exception of Netflix's video player which makes it flicker blue - Youtube and local video are completely fine).
What I cannot do is plug in this monitor whilst the XPS13 is on already - which is inconvenient as I move on and off desk a lot, and powering down the computer every time is unhelpful. Oddly, the monitor will also not be recognised if I simply Restart from Windows. I have to fully power down and plug everything in before switching the computer on again.
I have updated BIOS, video card and Thunderbolt drivers since and none of these has solved the problem. My system info is:
DELL XPS13-9350
Windows 10
Core i7-6560U, Intel Iris 540 graphics

I have a Dell XPS 13, model 9350 (released Fall 2015), with the matte 1080p display (non-touch).  It has the new USB-C / Thunderbolt 3 port to connect to external monitors.  It requires an adapter to connect the USB-C port to HDMI inputs on external monitors
I have purchased two different USB-C to HDMI adapters and have tried connecting both to my relatively new LG LA6900 1080p HDTV as well as an older 1080p computer monitor, both with HDMI inputs.  Regardless of which adapter or external display I use, the colors come out washed out with very poor contrast when I export to the displays.  Regular greens and blues become neon, the whites are so bright they wash out all detail, browns are a light yellow, etc.  In general, the contrast and colors are so off that the external displays are pretty much unusable.
I have used both of these monitors as external displays for several other laptops with no problems.  I never have to adjust the monitors’ settings or the computers’ settings.  With the Dell, I have tried every imaginable adjustment on the monitors.  I have also used Windows 10’s color calibration tool.  I have also played around with the display driver’s settings. I also tried using several different HDMI cables. NOTHING fixes the bad contrast and washed out colors.
By process of elimination I know, therefore, that the problem lies in the Dell.  I have spent hours on the phone with Dell tech support.&... Read more

Answer:Dell XPS 13 9350 improper contrast / colors via HDMI on external display

Regarding the notebook, am I correct in understanding that the color problem only appears on your two external monitors and not on the LCD of the notebook itself? If this is correct then I don’t suggest reinstalling video drivers, if the LCD has a good display the drivers aren’t going to be the problem.
Have you tried other connections than thunderbolt to HDMI? Does the TV and monitor have Display port, standard VGA or DVI connections that you can try different Adapters with?  I certainly understand how you may not have these extra adapters lying around but if possible, this may be a way to see if it’s a problem with the type of adapters you are using, or a problem with any type of adapters.  You mentioned you have tested both displays on other notebooks, where you using thunderbolt to HDMI adapters on these other notebooks?
I mention power options on a lot of my posts but with notebooks you can’t emphasize it enough, I certainly suggest testing with the AC adapter connected to the notebook, and the Windows Power options plan set to High Performance and check to see if that makes a difference.
I don’t know if I suggest a service right now, especially if I am correct in understanding that the image on the LCD is fine but it may eventually be something to try. I will shoot you a DM to get your information if this turns out to be a suitable option.

I'm wondering if someone possibly help as I'm not sure where to go next.

I have a Dell U2311H monitor connected to a XFX Radeon 6850 via its DisplayPort and I'm having problems with random flickering where the monitor picture goes black for a few seconds.

I have another monitor, an old HP, connected via DVI and a 1080p Sony LCD TV connected via HDMI.

I have had the Dell and HP monitors connected via DVI for months without any problems but I wanted to extend my Win 7 desktop to all 3 displays and I believe you can't do that using DVI, DVI and HDMI, hence why I want to use the display port.

I have tried 2 different displayport cables, so I don't think it is that. I don't have another gfx card or monitor to try to eliminate from the process.

One thing I did notice is that if I change the resolution from 1080p to 720p it seems to fix the problem. I'm wondering if it could be something to do with the displays running at different resolutions? Although I did try both the TV and Dell running at 1080p but there was still a problem.

Any suggestions greatly received,


Answer:Display port flicker on Dell U2311H monitor


I happen to see this thread when searching for solution for the same problem. I am using 3 monitor display setup, using U2311H connected with displayport to HD 5770 graphic card and 2 samsung 940b monitor connected with DVI to the same HD 5770 graphic card.

U2311H flickers (screen become totally black) for 1 to 2 sec at random times and return to normal.

I did not try any other display port cable yet because I did not have time to buy another one.

Seems like adbarnes have the same problem, I am wondering if it is because we are using 3 display setup? or display port? Or maybe there is something wrong with U2311h?

I have been using U2311H for some time, this flicker problem happens recently.

adbarnes, have you discovered how to solve the flicker problem?

My dell U2311H is using 1920x1080 (recommended) resolution
My samsung 940B is using 1280x1024 (recommended) resolution
(all using the recommended resolutions)
using win 7

I have a Dell Latitude E6410 running Win 7 Professional (64-bit). I have it connected to an external monitor. Whether I choose "projector" or the option to show on both screens, the monitor on the laptop will flicker. Here's more specific information that may be helpful:

The laptop and a desktop are both connected to a KVM switch. I set the laptop to "projector" mode so that it will, of course, project on to the main monitor. When I am accessing the laptop via the KVM switch, I see its display on the main monitor just fine. However, if I switch to the desktop, the laptop screen will intermittently come on and off. This happens over and over. That is what I describe as the "flickering." It's very annoying as I work from home and each time the laptop screen goes off and on, I hear a beep in my headset.

The laptop uses Intel HD graphics. The driver date is 01/30/2013 and version is The laptop resolution is set to 1024 x 768 with a refresh rate of 60. Windows does not find a newer version of the graphics driver when doing a search. The laptop will also give this message when flickering:

I recently purchased an XPS 15 9550 with i7, 16 GB RAM, 256 GB SSD, and GTX 960m dGPU that I have connected to a 27-inch QNIX qx2710 2560x1440p external monitor. I have this connected through a Cable Matters USB-C/Thunderbolt 3 to DVI-D adapter and cable.
The monitor and everything seem to work fine at 60hz, except for every time I unplug, turn on, or restart the monitor/computer the first five or ten minutes of use is plagued with constant screen flickering and flashing. After ~five minutes the monitor seems to stabilize and will only rarely have a single screen flicker. 
I have read other forum threads describing similar issues with different monitors/cable setups and that there is likely an issue between the wifi card and thunderbolt port. The common recommendation is to turn down the wifi output percent to 75%, however the Killer wifi card on this computer does not have an option under advanced settings to turn down the power output. Has anyone had any luck doing this on a recently purchased XPS 15 with the Killer wifi card?
The cables and adapters are new and the BIOS and all drivers are up to date. Other than the wifi issue, does anyone have suggestions or solutions to this screen flickering problem?

Answer:XPS 13 9350 not working on external display

This issue can be resolved by updating the Thunderbolt controller driver to version ,A01 and also updating Thunderbolt firmware to version 02.11.06 ,A02.  Both of these drivers are available from the Dell support site. Besides this update your Graphics driver and the BIOS firmware to the latest version. That should ideally solve the problem.

I have noticed that whenever the (non-touch) screen on my Dell XPS 13 9350 refreshes (e.g. with the mouse pointer moving, webpage scrolling, etc.) I hear a buzzing sound from the bottom left of the display.
Uninstalling the Intel display driver and using the Microsoft Windows generic display driver stops this buzzing from occurring, but that also stops the screen brightness hotkeys from working so it's not really a solution.

Hello everybody,
I have an external USB 3.1 enclosure (Vantec Nexstar USB 3.1, model # NST-270A31-BK) that I am connecting to the USB-C (Thunderbird 3) port of my XPS 13 9350 laptop.  The drive does not start even after using two different USB 3.1 cables.  I have installed all the USB and Thunderbird drivers from Dell's website and activated the port in BIOS, but still have no luck getting the drive to run.
Thing is, when I plug the drive into one of the standard USB ports using a USB 3.0 cable, the drive boots up and is recognised by the laptop with no problem.  So if my troubleshooting was done correctly, the USB enclosure and cabling is not faulty, so the problem must lie with the USB-C port.  Has anybody successfully used the USB-C port to access external storage with any luck?


Answer:Dell XPS 13 9350 USB-C port and external storage

I am using XPS 13 9350. I have a Kingston Duo Flash Drive which has both USB C and USB 3.0 connectors. When I first bought the notebook, it was able to detect the flash drive, however transfer was very slow. After a series of driver updates, it can no longer detect the drive. However, the drive works when I use the USB 3.0 connector to plug it in the USB 3.0 drive. So I suspect it is the USB C port of my computer which is not working.
I have restored the computer to factory image and redownloaded the drivers, no luck getting it to work. Right now I am intending to send the laptop to Dell to check out.
Do you have any luck making the USB C port work?

Hello, I just purchased this i5759-8836SLV (Windows 10) laptop that produces a very poor display on an external HD monitor (HP 22VC) when connecting via the HDMI port. It has an integrated Intel Graphics 520 and an AMD Radeon R5 M335 (4GB) dedicated graphics card.
The contrast ratio is very poor and the colours are dull when comparing to the laptop screen, with both displays set to 1920 x 1080 resolution.
I have switched HDMI cables and even monitors, with the same results. When I attach the same monitor to a different Dell laptop, the display works just fine. The image is very crisp and the colours are very bright and default factory setiings.
I have downloaded and installed the latest drivers, tried adjusting both monitor and graphics software settings without much success, the display still doesn't look as sharp and bright.
I have tried explaining the issue to Dell tech support, but without much success. The believe it is a monitor issue, as the laptop's built in display is working fine.

My XPS13 9350 was one of the first with USB-C port (Thunderbolt 3) only and no DisplayPort, supplied in early 2016. It has caused a lot of headaches. As I tried to connect my external Dell monitor using  a USB-C to HDMI adapter from Dell (part no: 47KD7) there was no external display at all. Dell Support advised me to update BIOS. But it led to a complete freeze of my laptop and Dell replaced the motherboard. (It was a real nuisance as I use my laptop for work!!)
With the new motherboard,  the laptop/USB-C adapter/external monitor worked fine for 15 months. Until one day, out of the blue, the external screen started flickering with an image that was all distorted (cut in the middle). The laptop screen was fine. After a few weeks of flickering, there is no signal at all to the external screen. Moreover, as I connect the adapter in USB-C port the resolution on my laptop screen changes.
I know there have been a lot of issues with USB-C connector on XPS 13 and 15.  I have reduced wifi-power to 50%  but it has had no positive effect (several persons have said on this forum that it helped the video output). 
I am grateful to learn if anybody with similar problems found a solution. Cheers

External out using VGA and my Acer AL2216W shows flickering especially when there's movement on the screen (animation/video running). By flickering I mean thin lines running across the screen. Not thick enough to be a hindrance but very noticeable especially in videos.I originally thought it was the VGA out's fault. Turns out this only happens when I'm plugged into the AC. When I'm running off the battery there's no flicker. This happens no matter which wall outlet I use or surge protector.Changing power adapters with my room mate's didn't help either (he has the same model). Seems it's the power unit inside the laptop?

*Where's that edit button*...The problem occurs on my room mate's Y410 as well.I'm guessing it's due to improper shielding inside the laptop.Does anyone else have this problem? Is this something that Lenovo guarantees an easy fix for if I shipped it in aka is Lenovo aware of this problem?  Reason I ask is because this is my sole computer (no desktop). So I will be without a computer if I get this RMAed.

Okay guys i have a puzzling one for you... I'm running my trusty Emachines E527 with Windows 8 RP. I was playing Minecraft on an external monitor (a TV) and I get a blue screen... no biggie I've dealt with these before. I do a hard reset and turn my computer back on and I don't get an image on my laptop screen. I take a flashlight to my screen ( I've had back light issues before thought it might happen again) and nothing... no image or anything. I decided to take it apart and use a voltage tester on the inverter to see if it's even sending power to it and I don't get a reading anywhere. Furthermore no external monitor hookup will display an image either

This must be a software error... though I don't get a boot splash either..

This one is beyond me.. someone on another forum suggested clearing the cmos. I only have a battery in there on my motherboard but it is soldered to the board itself... kinda hard to clear...

I leave on vacation tonight and I need my laptop so any help would be greatly appreciated....

I have a Dell Inspiron 1012 running Windows 7 Starter SP1 and I've got it hooked up to my Protron 42" LCD screen with HDMI cable. I changed the flicker rate to 70 Hertz without checking the Proton's maximum flicker rate - yeah, that's really SMART - so now I've got an issue with my external display.

It worked okay for second but then my laptop screen turned black and the external display reads "Signal Out of Range" (duh, the Protron works only up to a 69.8 Hertz flicker rate, which I SHOULD have checked BEFORE changing it, but what's done is done -_-).

Any time longer and I have to start the process of removing and inserting the plug and playing with my external monitor so it can detect a signal, it usually takes a few tries and a few minutes.
The white screen is always on my laptop throughout the process and even when the external monitor works.
Just determining if i should replace me screen or ribbon video cable or check my connection to my vga cable or could it be my motherboard.

any help or direction is appreciated.
Thank you!

Answer:Dell Inspiron 15R N5110 screen problem - white screen & external monitor works if I jiggle the plug

We need to isolate if the issue is with the LCD or the video card. So, turn off the system - press and hold the "d" + power key to turn it back on - this should initiate the LCD built in self test. You should see a screen with solid changing colors and the system would beep. If you see this - the LCD is fine. If you do not see the colors changing - then repeat the step again - but this time - swivel the LCD back and forth and see if there is any display. If the display is intermittent then the LCD cable needs reseating/replacing.
Also, turn off the system and press and hold the "fn" key + power button to turn it back on - wait for a few minutes. If you do not see any display, the system should start beeping. Count the number of beeps per cycle. At any point if you see the screen with solid colors changing - the LCD is fine. The issue is with the video card/motherboard. If do not see the changing colors - then we would suspect the LCD.
Test the system with another VGA cable for the external monitor.
If the system is under warranty, then please send me the service tag of the system and your contact details through a private conversation. Or you could use twitter - @dellcares - we can DM through twitter and help you fix the issue.
Keep us updated.

Issues again with laptop monitor.  Passes all hardware tests.  Did a complete reinstall of Windows 10 using MS Media creator.  Laptop monitor worked with 2006 MS Generic Graphics driver but when updated, laptop monitor went blank but external monitor started working.  Believe this is a driver problem but each one I try has the same result.  
Had same issue in January.  Was under warranty at the time and ultimate result was to reinstall Windows from Microsoft, motherboard was also replaced although the tech didn't believe it had anything to do with the problem.  Laptop monitor worked fine until a couple of weeks ago when new Windows updates were installed.  I have seen several other posts that are describing the exact same issue.  
Currently, I have latest drivers for the graphics -, Windows 10.0.15063.  At this time, my nice expensive laptop is just a desktop.  Any suggestions on what to try next?

On other laptops I've used, I've been able to see my laptop screen while simultaneously projecting to an overhead or external monitor. I can use F5 to toggle between screen, external, or simultaneous. This works great for presentations. With my A70, however, I can only toggle for screen or external/projector, not both simultaneously.

Any help on solving will be appreciated.

hello friends DELL users, can you help me? As I am getting older my eyes and neck are not in good condition. I decided to buy DELL monitor - Dell P2217H Professional and I realized there is no HDMI or DISPLAYPORT at my laptop. I bought port replicator DELL - Dell USB-C (M) na HDMI 2.0 (F).
Since I connected all above mentioned devices, my laptop went crazy. No chance to make it sleep and if I switch it off and on, it will not recognize being connected to external monitor. Sometimes laptop does recognize external monitor, but only duplicate the screen. Any advises pls?
Dell CS did not help so much. They sent technician to change MB and it is the same. I reinstalled WIN 10 (factory reset) and the problem persists.

Hi, I own a W510 updated with the latest lenovo drivers. The problem I have is that when I use an external monitor connected via the VGA port I see horizontal lines moving across the screen, which I can only describe as flicker. I've seen this with two 22" 16:9 monitors already - one Lenovo and one Packard Bell. With the Lenovo monitor I see that in the NVIDIA Control Center the refresh rate is set to 59 with options 60 and 75 available. With 75 the flicker is still there but not that apparent. I can't set to 60 because it automatically reverts to 59. If I however connect the same monitor via the DisplayPort to DVI connector there is no flicker and the refresh rate is set to 60. With a third Lenovo screen, which is I think 15 inch 4:3 I don't see any flicker. Do I have a defective VGA port? Is this a driver issue? Should I contact support?

I updated drivers on all devices, including setting the XPS to do nothing when lid is closed. External monitor works fine, until XPS lid is closed, then external screen blanks. However, monitor works fine in airplane mode, which does me no good, as I need an active internet connection for certain software functionality. Also, airplane mode disengages my wireless keyboard and mouse, and I need to turn connection back on and pair devices (wasting more of my time). Is there anyway around this issue, other than returning the TB16 for something that works?

Hi, I recently bought a 22" LG Flatron Monitor and a Toshiba Satellite Pro Laptop and have a flicker happening on the LG monitor whenever the laptop is plugged into an outlet. The flicker immediately goes away when the laptop is running off of battery power. The resolution is on the native 1920x1080 and refresh rate is 60Hz (can't change it). I have had this problem before with a HP laptop and BenQ monitor. The problem only happens to me at work (not at home), so I believe that is has to do with electrical noise on the circuit at this particular location. Anyone know of ways to get rid of or filter this noise to eliminate the flicker?

Check the cable that runs between the mainboard and back of the display panel.  If it's damaged, replace it.  That doesn't solve the problem, the next suspect is the mainboard.

Bought DELL XPS 15-9550 with intel Core i7, 16G RAM, 1TB SSD HD, with Nvidia-GeForce GTX 960M from Best Buy last November.
Connected to external monitor HP2311xi through the HDMI.
Everytime need to set up display as 2 display, HP as Main and laptop as extended. Then every 5 to 6 min, the system reverted back to single display by first blanking the screens.
Reset the display by clicking detect and the laptop screen come back alive, and then after 5 to 6 same thing happened
Talk to Geek Squad. Change the cable, update the Intel HD graphics drive, reinstall and uninstall. Still happening
Update BIOS to the latest available still not solve the issue
Even after letting it in single display mode, the blanking keep continue. It is very annoying and distracting while working.
Any one encounter the same issue.  Please share the resolution
Thank you

Answer:Dell XPS 15-9550 with External Monitor HP2311xi - keep getting blank screen on and off -

I am having the same issue with my XPS 15-9550 with Nvidia combined graphics connected to a Dell UP3216Q external monitor.
Typically when interacting with apps, i.e. scrolling in MS Edge browser, the external monitor blacks out for a few seconds. It is very intermittent, and tends to occur several times within a 30 second period then it will stop for a while. Acts like bad HDMI cable connection. I have the same issue with multiple cables, although it could be the receiving connector on either the laptop or the monitor.
Have changed drivers on both the Nvida and intel adapters with no change in behavior. Changed resolution, frame rate, etc.
The problem renders the system unusealbe and I will have to return both the laptop and display if not resolved soon.

Recently I've started noticing a monitor 'flicker' that is a brief shrinkage of the screen display on my monitor, perhaps by ~5%. It is hard to define when it happens and exactly describe what happens. It always catches me unawares.

The Dell Ultrascan P990 came with a machine I purchased in 1999, so it has given me good service. My Sapphire Radeon HD 3870 PCIe 512 Mb graphics card came with a machine I had built for me in 2008 (see my specs)

I'm currently running Win7 Pro x64.

Could this flicker be a sign that the CRT or other monitor circuitry is failing?

My son gave me a hand-me-down Samsung S24A450BW LED monitor. I've not switched to it because photo forums I've checked suggest that the CRT monitor should give a superior image.

Can anyone offer any insights?



Answer:Occasional Brief Flicker - CRT Monitor - Dell P990 Trinitron

hi yes from your description it seems like the monitor is failing. can test that by hooking it up to another computer. you could always hook up the Samsung as a second monitor and see how good the image is on that compared to the crt monitor.

My laptop screen just doesn't display anything (look like when the computer is off) but when I connect the external monitor, then the desktop will be displayed on that monitor. I tried to recover the laptop using the recovery disk and it worked again, but today, it stopped working again.

I again have to plug in the external monitor, and after I tried to reboot, I keep pressing F8 but the start up mode doesn't come up, only the sound of when you keep pressing a button for too long beeps, however, the laptop monitor works again.

How do I fix this problem?

Answer:Satellite M30X-111 screen doesn't display anything but external monitor works

What do you want to do? Do you want to recover the notebook?
If yes, you don?t have to press any F8 but you have to boot from the Recovery CD by pressing the C button immediately after notebook starting.

But this issue sounds like you have switched accidentally to external display.
I would recommend to checking the option Fn+F5. This combination let you to switch between the display and external monitor.

I am busy finding my way with a new Dell XPS 13 (9350). Many of the programmes I have display very well, but sometimes they programmes that load are so small that you need a magnifying glass to navigate your way around the screen.
Microsoft Office, for example, has no issues,
When I load my Adobe Photoshop Elements, the display is so small that I can hardly see anything.

How do I go about setting up the display so that it is easily readable? The attached screenshots hopefully illustrate the problem I'm having.
Sometimes - even in my browser - one section of the browser will display legibly, but another section of the screen (possibly linked to a java application) will display incredibly small.

Example of a website that displays inconsistently.

Switching to an external monitor  (AOC brand) from the built-in utility of the X201 (Fn+F7) works fine from startup. However, on wake-up, the monitor will flicker so bad it is almost unreadable, even though it had been connected just fine. Changing the monitor settings seems to have no effect. Re-booting the X201 cures the problem. I have a good quality VGA connector between the X201 and monitor and am not using the Ultrabase.

The other day, I started having a problem with the screen on my latitude d610 laptop. After awhile of being on it would turn off. Not the laptop itself, just the screen (I know this because I can hear the audio coming from the task I was working on). This problem got progressively worse and now when I turn the screen on it only flickers on for about a fraction of a second before going back off.

I'm not entirely concerned with getting that fixed (although, if you know what the problem is, please do let me know). My main concern is the fact that I cannot get an external monitor to work. I have plugged in the VGA cable into my laptop and the external monitor and then I hold down the "fn" key and press the "CRT-LCD" button, but nothing happens. There is no problem with the VGA cable I'm using or the monitor I'm trying to use, because I tried troubleshooting with another laptop and was able to get it to work on that second laptop. The only thing I can think of is that maybe my d610 is not recognizing the VGA cable/external monitor, because after plugging the VGA into my d610 I do not get the "device is connected" chime that I would normally hear after connecting a device.

If you have any advice for me on what my problems could be or anything you think I might be able to do to try to correct the problem, I'd certainly appreciate it.

When viewing the Dell Optiplex 9030 specifications, it states that the device can be used as an external display for other devices, via its HDMI input.
I have followed the instructions given in the link below to link-up a MacBook Air as a video input, using HDMI. One user in the thread below says they have successfully done this, although it is not working on my machine. 

When I switch the display from "PC" to "HDMI" using the OSD (On Screen Display) buttons it only shows a black screen, although my MacBook Air detects that it is connected to the Dell Optimax 9030, and adjusts its settings accordingly. On the Optimax 9030, the question-mark below where it says "HDMI" on the OSD disappears, but no signal is displayed on the screen.

On power-up, the built-in display shows the Dell logo then goes to a black screen.  If I attach an external monitor via a DA200, I can see the Windows 10 login screen and log in. 
The only way to have Windows show in the built-in display is to disable the Intel Iris Graphics 540 entry in Device Manager.  When I do this, I am unable to display to the second monitor/change the brightness of the screen, Windows has no sleep option, and etc...

Recently, my XPS 13 (9350) with Touch screen will just boot to a black lcd screen. I have a dual boot with Windows 10 and Ubuntu. When I turn the system on, I can get past the dell logo to the operating system select screen. However, once I got past that screen, it just becomes a black screen. The only way to get it to work was to use an external monitor. When I used an external monitor, I did notice that the touch screen still worked despite the laptop lcd showing no image.
Since, it was happening on both operating systems, I suspected a hardware problem. I found a post on this forum that suggested running the lcd diagnostic, which showed no errors. Another poster said swivel/jiggle the laptop screen up and down. When I did that, the lcd screen image came back. I think there must be a loose connection somewhere or maybe a wire in the hinge is starting to fray?
Just how bad is this issue? Will it get worse? I have owned this laptop for almost one year already and warranty is probably still good for 2 weeks or so.

Seen a few people seem to have almost similar problems. Rather than the whole screen flickering though, it is just the lower third of the screen and its flickering aswell as not updating - i.e. totally useless.
Tried updating the drivers, restoring to before the last system update and no change. Seems like it is not a screen hardware thing since it will briefly stop if I tax the system more.

New XPS 9350, been using it for about a month. Except the Thunderbolt connecting to a 4K display issue (sorted out with keeping the lappy in airplane mode and having internet access though USB 3-LAN cable) everything seemed very good. Until yesterday when on an important meeting the screen while working on battery power, the screen went blank. Tried to reset with holding the power button down for about 10 sec. The button LED and the keyboard lights cycled, but the screen remained blank (no DELL logo on boot as well). I connected the power adapter, the screen came on. Few moments later it went black again. Cycled the power, no response from the screen this time. I did a quick browse for solution and found a guy claiming that disabling C-State in the BIOS has fixed similar issue. The problem is that this time no matter how many times I reset though the power button the screen remains blank... Eventually after 20 min the screen appeared and I managed to get the BIOS changed (disabled C-State). The rest of the day the XPS was working fine and I tough the issue is gone. Until this morning, when I opened the lid and the screen was black again. So, back to square 1.

Since I purchased this laptop under two years ago I've had so many problems with it I've lost count.  It regularly gets bricked after Windows forced updates, most recently a few days ago.  I tried reinstalling Windows and managed it a couple of times but after a while the screen just goes black. The most recent time, the screen went black during re-installation so I now can't even finish the installation (and you can't do this in Safe Mode).  I know Windows is still trying to install as I can hear Cortana trying to set up.  But now I can't see anything in order to finish the installation so I'm stuck, unable to do anything.  I have no external monitor I can use but in any case, if this is a hardware issue, this is not a fix.
I've run diagnostics via F12 a few times and it shows no hardware issues but who knows, it could be.  Since I bought this, Dell have replaced almost all the hardware inc. motherboard and SSD. I'm not sure what else but I noticed today in BIOS in the log dated May 2016 (one of the times it was 'repaired') that it states, "...primary battery is not identifiable...".

My friend is having lots of issues with his moniter and screen flickers.

I'm fairly certain that the issue is the redraw rate but haven't been able to make any headway.

Sadly, it's next to impossible to change any relevent settings considerig how bad the problem is. I'm asking if anyone has a pinpoint solution so I'm not guessing while fighting the clock, since the problem seems progressive the longer the computer is running.

So sorry, I don't have any relevent information regarding the drivers or adapter seeing as... well, I can't see. I do know that the monitor is an 566LM made by LG, and is only about 3 years old since purchase.

Next step is getting another monitor over here to work with, but I was hoping that someone might tell me something that might save me a tiring trip up and down 3 flights of stairs with a big old monitor.

Odd problem with monitor; When using Microsoft Works and a few other programs, I get thin dark greyish horizontal lines across screen that go up and down the screen at probably--but just guessing here--the screeen refresh rate.

Annoying, and am wondering what's causing it -- any ideas? Had monitor since January 2006, problem started about a month ago.

Here's NVIDIA settings I'm using:

GeForce MX100/200 EGA/VGA card (32 Mb)
DirectX 9

Screen Resolution: 1280x1024
Screen Refresh: 60Hz (Have tried other values available -- 70, 72, 75 Hz -- still get the lines)
Color Quality: 32-bit (Also get lines with 16-bit)
Image setting: Performance (Get lines with High Performance, & Quality Settings)
Antialiasing: Application controlled
Anioisotropic filtering: Application controlled

Digital Vibrance: Off

NVIDA Desktop Manager Version 61.76; Driver Versions:
Had theory I might be pushing the Video card too much & need to drop resolution down to say, 1024x768 or less.

Theory #2: Could it be electrical interference causing it? Haven't moved anything on the desk though....

For some reason I get a screen flicker that is noticeable and irritating. It happens with every BIOS after 1.2.00. Not sure why, but if I want to get rid of screen flicker I have to back to BIOS 1.2.00. Has anyone else experienced this problem and/or found a fix? I think it is rather unacceptable for a $2,200 laptop with a 4K screen to have screen flicker issues and for it to continue to be a problem with the last three BIOS releases.

I've purchased a Dell XPS 13 9360 and I've had problems with the video flickering.  It happens about every 5-10 minutes for about 5 seconds.
I've spent probably 30-40 hours trying to resolve the issue and I'm pretty fed up with it over the last 2-3 months.  I didn't notice it enough to decide ultimately to get my money back but it is too late.

I've run the diagnostic tool, and it apparently failed.  A technician was sent to my house to replace a part of the computer not related to video, and the part was refurbished.  I declined opening the device up and wanted to get my money back.  Apparently this test always fails unless the computer is plugged in apparently.  I found this out after the technician left...good I didn't let him replace a non-related part!
I've realized my 30 day return window has passed.  Gulp! That's after spending a few hours here and there trying to resolve the issue. Now I have a machine with an issue that is going to take plenty of hours to diagnose.
I've updated the BIOS, updated the Video drivers, to no avail.  I've now engaged Dell Chat support, who has stepped me through the entire process of doing this all over again.
At this point, I've asked for an escalation.  Normally this has been easy in the past, but I'm being forced to step through a repeat of the troubleshooting process which I've already accomplished

Thanks in advance,

Lately, my monitor has been flickering a bit too much. I changed the refresh rates around but it still happens. Sometimes after restarting the computer, the problem is fixed. There is also another problem where the monitor display seems slightly yellow. I can see a faint yellow colour on the display screen which is quite strange and this is also fixed sometimes after restarting. Does anyone know what the problem is? Could it be the monitor or is it more likely to be my graphics card? My monitor is quite old, about 6 or 7 years so I would suspect it being that.

Thanks for your help.

Answer:monitor displaying yellowish screen and too much flicker

The faint yellow colour sometimes can be corrected using the monitors built-on Degauss feature. Try it, it worked for me before.

Hey guys, just got a problem recently with my LCD monitor. It's a fairly old one (Acer 17"inch) and I'm suspecting that it's simply dying on me.

The problem is that whenever I power on my monitor, the screen flickers on for a second and then immediately off. Probably something with the backlight. The power button stays on but the whole screen is black. I usually try it a couple of times to power on/off and eventually it will work and then as long as my monitor stays powered on everything works as normal.

Sometimes especially (I think) when my heater is on in my room, it seems it works almost immediately or very quickly. But when it's cold it can take up to 5 min or longer to finally work. I'm not sure if it could be something based on the temperature, but I have no doubt it's something with the starter/backlight.

A quick google suggests that a dying monitor would usually flicker when it's on (backlight problems), but I don't have this at all. If I get my monitor on, then it works fine. The only problem seems to be something with the starter, but I'm not sure exactly what. Perhaps it's just getting old?

Is it worth to try and repair it? Or should I just wait it out until I can no longer get it to work and then just buy a new monitor?

Answer:Monitor flicker + black screen on startup

lcd monitors have very few replaceable parts. infact one of the few replaceable parts is the back light in some models.
however its a tricky job and normally costs more than a new monitor.
older lcd monitors use a type of fluorescent light, these tend to have a life span. the fact youve noticed there's a corrilation between temp could point to a dying capacitor that only works efficiently when warm.

if you shine a torch on the monitor when it is flashing/dark you should just about be able to see whats being displayed. this will point the finger at the back light being the culprit.

personally id treat yourself to a nice new monitor.
when you can get the liyama E2278HD-GB1 for around ?100 ($100 as us brits get stiffed on import taxes) youll not only gain 5 inces but also get a cracking budget monitor with the quality of a more costly one

Hi, I recently purchased a Dell Inspiron 7559 for school, my first laptop ever. It took me about 6 months to finally decide on a laptop, and I'm very happy with's beautiful. But, I've had two problems with the display. First, there is some slight yellow discoloration on the right half, not a big deal, just my ocd, probably just some backlight bleed or something. But the big issue is that the screen brightness flickers constantly. I can only really notice it on the lower brightnesses, but I use those so its a problem. I've tried EVERYTHING. Tons of driver fiddling, power option fiddling. I cant tell if it flickers in the bios screen or lcd bist, but I've disabled both NVidia and intel HD graphics drivers and no matter what I do, it still flickers. This makes me think that this Is a hardware issue. If anyone has some insight, I would really appreciate it. Should I send it in for repair, or just wait a bit as I read online somewhere that the lcd backlight needs to "settle in" for it to stop flickering with takes a decent amount of screen on time. Sorry for the long post, but this is my first pc and I'm a little bit picky about the function of my things. Thanks.

When I start my PC and turn on monitor, the right half of my monitor comes up as not viewable.  It isn't blank or dark, but a myriad of colors that cover that side of the screen.  The left side is fine.  To become viewable, I must go to a internet startup page that is virtually all white.  Then I power off my monitor, then back on.  The right side flickers for quite a while, gradually "settling" into the white screen but if I try to move to a new program or open up a page online, the screen flicks back to the unusable colored screen.  It takes several attempts and about 30 minutes before my repeated attempts finally work and the screen settles to where the full monitor is viewable. I have disconnected and reconnected all cables to the monitor, and that hasn't resolved the problem. What is the problem I am having and how do I fix it?

Hello, I would love to ask for some help!
I've recently purchased the newer Dell XPS 13 9360 Non-touch (not the 2 in 1) and am having some trouble with using an external monitor. The screen (on the external monitor) keeps on flickering and has a very unstable connection. 
I've searched and found that apparently lowering the power output of the WIFI network adapter can fix this problem. 
The problem is that the current XPS's wifi adapter doesn't allow the power output to be changed. The previous fixes were geared towards intel wifi adapters.
The general power settings for the computers doesn't show wifi card power controls.

I have updated all the drivers for the computer including the wireless adapter. Still the options doesn't change.

Has anyone found a way to get a stable external monitor to work with the Killer Wireless Adapter cards?
Any help would be greatly appreciated!

Answer:XPS 13 9360 External Monitor Flicker with USB C - HDMI Adapter [Killer Wireless Adapter]

For what it's worth: For me (XPS 13 9360, QHD, i7, 16 GB, Killer WiFi), external screens are perfectly stable, even with wireless being on relatively high throughput load, albeit not high power (energy) load.
I am connecting both HDMI and DisplayPort displays, each with cheap native USB-C adapters (i.e. through Thunderbolt). I also have full success with a Dell DA200, through its built-in HDMI graphics adapter.

Having a very strange (and annoying) issue with the display. I can only see the display on my Twist after connecting it to an external monitor first. If I do not, all I see is a black screen. No cursor, no anything. If I connect it to an external display via the display port to VGA adapter, it works fine. If connect it to an external display and then disconnect my external display, the display will remain on the Twist. However, if I reboot, I lose the screen again until I connect it to an external monitor. I made sure that "PC Screen Only" is chosen in the Fn+F7 option. This is obviously a serious problem. This is for company use and our users will not have a VGA monitor handy with them where ever they go. I checked the hardware manager and all the drivers are installed with no warnings.

Answer:Lenovo Twist display issues - No display unless I connect to an external monitor

Figured out a work around and narrowed down the problem. If I hit the Second Screen key (F7) after booting, it will go PC Only as the first choice and bring up the display on the laptop after a few seconds. The puzzling thing is why it seems to choose the external monitor as the default monitor on boot, even if it is not conected. I've tried running System Updater to make sure that I have all the latest drivers. All the display settings appear to be correct.

I have Dell Inspiron 5547 laptop (Touch Screen, 15 inches, 16 GB RAM and i7 4th Gen processor, Out of Warranty). Some days back, suddenly the display went dim and anything is hardly visible. After some initial investigation, the display chip (may be VGA or LED display chip) on the motherboard appears to be burnt out (may be due to voltage surge). Even the numbers printed on the chip is not readable because of which it is difficult for the local repairing shops to repair this problem.
I think Dell India Service Center doesn't deal with chip level repair and hence replacing motherboard is the only way they can fix this. This will be very costly (considering that the laptop is not under warranty so will have to pay for warranty extension, motherboard replacement and repair service) and time consuming.
Hence, to avoid all this I have come here to seek some assistance.
If there are anyone using the same laptop (Inspiron 5000 series 5547 Touch Screen Display with i7 4th Gen Processor and 16 GB RAM) then could you please take a clear picture of your laptop's motherboard or if you recognize the display chip then only that should be sufficient. In this case, I can read the chip related number from the image and try to repair it.
What are the charges for buying a warranty for the laptop, motherboard of my laptop and repairing charge? 

Request your response and help.

Answer:Display Issue - Dim Display for Dell Inspiron 5000 (Model 5547) - Touch Screen Display with i7 4th Gen Processor and 16 GB RAM

You'll have to call Dell about the possibility of a warranty extension;  in the US, it's sometimes possible but will likely run over $300 -- or about what a board replacement would cost.
If you're getting video, the GPU is OK -- and it's more likely the power circuit to the backlight that's bad.  It'll likely cost as much to repair as to replace the board -- though you'll still be putting $300-400 into an out of warranty system, so replacing the system may be a better idea (if you do this, consider buying a 3-year warranty with the next system).

Hi, I have two major issues. I'm connected to an external monitor using a display port to hdmi converter, and an hdmi to dvi cable.When I am on "Energy Saving" (switchable graphics) mode, the external nomitor blinks every 5-10 seconds, but it is perfectly fine when I am under "High Performance" (switchable graphics) mode, so I'm not sure that it's the cables/adapters/monitor that I am using. The second is I cannot change my brightness using fn+home/end when I go through this process: In "Maximum Performance" (power plan) mode (while plugged into ac)unplug acGo into "Maximum Battery Life" (power plan) modeplug in acplug in external display to displayportGo into "High Performance" (switchable graphics) modeuntil I change back into "Maximum Performance"(power plan) mode then back into "Maximum Battery Life" (power plan)mode then back into "High Performance" (switchable graphics) mode. This is a bit annoying, but at least I found the steps to temporarially work around the problem ... edit: Okay it happend to me again, but i can't fix it (haven't tried a reset though, but i don't want to bc I just started the computer and that's ridiculus).Also, I can change the brightness fine when the computer is in Energy Saving" (switchable graphics), but I get the blinking problem, which is why I mentioned it earlier.

After the recent Windows 10 update, my wife's laptop no longer displays on the external monitor. All was well before the update.

I am comfortable that Windows sees the monitor because clicking on Display Settings shows two displays. If I unplug the HDMI cable, only one display is shown.

I have confirmed that the monitor works by trying it with another laptop. I have also changed the HDMI cable between the laptop and the external monitor.

Device manager reports that I have the latest display driver installed.

I would appreciate any and all suggestions.
