Dell Laptop Screen Horizontal lines at boot or wake up

Question: Dell Laptop Screen Horizontal lines at boot or wake up

Recently my Dell XPS laptop on boot up or waking from hibernation has a few horizontal lines scrolling upwards; sometimes it has a gray screen with lots of horizontal lines on it. If I move the laptop lid back and forth the screen is fine.
I have run Dell diagnostics and all is reported as OK. I have taken the back off and all seems OK. I assume there is a connector between screen and computer but I cannot locate that. I assume that if a display setting has changed, the screen would be constantly poor?
Any ideas?

Preferred Solution: Dell Laptop Screen Horizontal lines at boot or wake up

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

My daughter's hp pavilion dv6-6163cl entertainment notebook has begun to show a gray screen with horizontal lines at start up and after sleep (opening the laptop cover). This lasts for a few moments, then her log in screen appears. There is no sound when the screen appears and no mouse visible. It does not happen every time the computer starts or wakes from sleep.

No new software installed; nothing downloaded. Microsoft Windows is updated.

What I have done already:

updated to latest Intel graphics driver
hp diagnostics test on hard drive and memory (via BIOS screen): both passed
Windows Defender Offline scan
Microsoft Security Essentials virus scan
sfc /scannow
chkdsk /r
safe mode and restart
"windows repair" after pressing f8
selective start up
malwarebytes scan
Spybot Search & Destroy scan
uninstalled McAfee and installed Microsoft Security Essentials
System restore to earlier time
BIOS driver updated

Haven't been able to tell if the problem happens in safe mode because it happens so intermittently.

Any thoughts are appreciated.

Answer:gray screen with horizontal lines at start up or wake from sleep

I think it is a connection problem between the laptop monitor and the base--my daughter just showed me the display flickers when she moves the monitor. I've read about faulty or loose wiring between the monitor and the keyboard/base of the laptop.

I'll try to see if we can get this fixed.

My laptop model is dell inspiron 15 7559 i7 4k touchscreen, i am facing a screen issue on my dell 4k UHD touch display, when i play any game the screen starts to show these horizontal lines (video link at the bottom)

I have a Dell E6410 and of late I have noticed that my system locks up with horizontal lines on my screen. No keys work and I have to hit the power button to shut down and restart.

It's a Core i5 with Intel Graphics running Windows 7 64bit.

It's under Dell cover and they already replaced the screen and motherboard but the problem continues.

I have ran Dell Diagnostics as well which ran without any problems.

I have a screenshot here. Any ideas on what could be causing this?

I recently noticed that my 2 month old M3800 laptop has 2 horizontal lines / bands running across the laptop display.  I have 2 dell monitors setup with no issues, the lines / bands only appear on the laptop screen.
Anyone else encounter this same issue? 
I am ready to contact Dell for a replacement / fix...

Answer:Dell M3800 Display with horizontal bands/lines across screen

This seems to be an issues with many M3800's I've had 5 different machines displaying this issue. The horizontal lines come at 1/3, 2/3, and at the bottom of the screen (the one at the bottom is easy to miss.) If you run the built in display test, the lines don't seem to appear but they show up quite readily if you use 3rd party screen testing programs (I use PassMark MonitorTest), specifically on Grey and Green colors and screens with horizontal gradients where the color changes along the lines.
Definitely get it replaced, but don't be surprised if the replacement ends up doing the same thing. (I've had two different 'fixed' units have recurrences of this issue.)

So what do you guys think it could be? I was thinking maybe a bad inverter, or ribbon cable? I'm not sure and would appreciate any info so that I can order a whole new screen, or a specific part, thank you.

Hi BC,
A (relatively new) Windows 8 (x64) Toshiba laptop has recently started to get horizontal lines across the screen making it illegible. This happens nearly every time the laptop wakes from sleep/hibernation mode or after being idle for a while.
The screen reverts to normal upon system reboot, so I assume it's software related... Any help/advise solving this problem would be most appreciated!

Answer:Horizontal lines across laptop screen :(

Please post the exact model number of your laptop in next reply. Also enter BIOS setup and inspect whether the lines can be seen from there. Usually you can enter the BIOS setup by pressing F2 during powering on.
If you can post a screen shot of the issue, that will also be helpful .

Hello, all,

Today, three times while I was playing games on my PC, the computer began behaving strangely (red dot artifacts appeared on the screen) and restarted. This was after I enabled automatic overclocking through my motherboard's BIOS. However, even after resetting the MB settings, I am suffering from system crashes. I can no longer boot into Normal mode - the computer restarts shortly after the Microsoft logo pops up. In addition, there are colored (mostly red) horizontal lines populating my screen, even in Safe mode.

I have tried uninstalling the display drivers and doing a system restore, but to no avail. I opened up the PC case and cleaned the dust from the graphics card fan, but I didn't notice anything in particular out of the ordinary with the unit. I strongly suspect that is a display issue, but before I resign myself to buying another GPU, I'd like to know if the cause lies with the drivers/software or more likely with the physical hardware itself.

Answer:[SOLVED] Can't Boot Normally, Horizontal Lines on Screen

A quick update: I tried moving the GPU to a secondary PCI-E slot on the motherboard. I was able to successfully boot into Normal mode the first time with no issue; however, after Windows began automatically downloading certain drivers, I noticed the red horizontal lines had returned. I downloaded and installed the latest set of Nvidia drivers, but upon restarting to complete the installation, the computer crashed once again. Thankfully, I was able to run perfmon /report before restarting.

I have a Toshiba Equium P200D-139 laptop and the screen stopped working. It lights up but the display consists of vertical lines, which slowly fade into a black screen.
I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.
After trying a new inverter with no success, I bought another second hand screen. However, the new screen has the exact same problem with the ‘horizonal lines’ display. Just occassionally, I catch a glimpse of a partial Vista screensaver for a split second but then its back to black. I’m not a technophobe, so any info would be very much appreciated.
Please help, as it is driving me up the wall!

Answer:Horizontal Lines on Toshiba Laptop Screen


No as that is a place to say hi, the software, hardware forum areas are where to ask questions on technical matters, but I have moved your post to the Hardware forum as its closest to your issue at present.

What Windows version do you have installed?
What model Toshiba is it?
Did you install any new software before this happened?
If you boot in to safe mode (F8 at boot) do you get the same lines?

At worst it could be the LCD panel on its way out, has the laptop been dropped at all?

Answer:Half laptop screen has horizontal rainbow lines

That's pretty much common in laptops/notebooks, it's a hardware issue. Try to connect the laptop to an external monitor; if everything is displayed correctly on the external screen, then your room-mate's laptop has a faulty LCD screen and/or inventer.

I've a Dell inspiron 15r se laptop which is 1.1years old( model - 7520). It was working fine until last couple of days. Last week it started giving a horizontal white dot line on the very top of screen( like this ............. in white) for the entire width of the screen. From yesterday or so a similar line started appearing at the bottom too. Both of these line will come and go every 2 or 3 sec. And screen will jump a bit (like say 5 pixel or so roughly) and it will also shake sometimes which makes letters difficult to read.
The problem exists everywhere, even in boot screen. In short when I press power button and screen start displaying something problem also starts.
Today I connected an external lcd monitor via vga cable and it works fine. No line and no flickering. So I guess GPU is ok?? What could be the problem?? Could it be just loose contact or something in laptop screen cable?

I have a Dell Monitor model # 1908fwpt and we have used it as an external for a few laptops now, and on the last two hook-ups it has constant, non-flickering white horizontal lines across the screen. The only resolution that doesn't is 1280x1024 for some reason. I have changed the cables, used both VGA and DVI, and run the self-diagnostics and updated all drivers. I have chased this issue up and down and not been able to come up with a way to fix it. The monitor is not old, it hasn't been used very much, and I really don't want to replace it...

Any thoughts? Since its done it on a few different computers I tend to think its not a driver issue, or a cable issue... And the one resolution it works on is all stretched out and flat.

I wasn't able to read what it says before the computer restarted.
Little back story, the computer had started running loudly which escalated to making a noise that almost sounded like grinding(or a piece of cardboard stuck in the fan). Couldn't figure it out so I gave up, last time I used it was January, but between last August and then it was only sporadic usage. A few weeks ago I turned it on again and there has been no abnormal noises, and out of no where I get the BSOD, computer still seems to be running fine.
Going to bed now, but will be on tomorrow afternoon to run any scans or give and needed info.

Hi everyone.
I have joined a new company and they provide 4K monitors to designers. So we had 4 items in the office, each being DELL P2415Q. I have hooked one up and it looked great. Then I got another one and I noticed the second one has faint grey static horizontal lines across the screen. The were visible closer to the center, but almost throughout the whole screen. More noticable when looking at it from top down. When I move my head from top to bottom I see they move comparing to the items on screen as if they were lifted a tiny little bit from the screen surface. I tried different cables, both DisplayPort and HDMI, I tried different PCs, even Mac. Turned out 3 out of 4 monitors had those gray lines and I was just lucky to get fine one as the first one. We ordered 3 more as a replacement and all 3 of them came with same grey lines. It's hard to believe 6 out of 7 items are defective. Did anyone have this before? Is there anything I can do about it? It's very annoying to have a super sharp monitor just to see grey lines all across eveything I look at. Mosty visible on white background.

Hello all.

I have a Dell Latitude D600 and at random times the display will flicker with horizontal lines. I can sometimes agitate it by gently twisting the LCD and it will flicker. I've done some research before and thought the problem would be the flex video cable, which I ordered and installed, but it still flickers. The LCD looks cosmetically perfect, as well as the inverter. The display backlight isn't flickering, rather there are white lines that flicker randomly, so I don't think it's the inverter.

I hooked it up via VGA to an external machine and only the laptop suffered the flicking so I believe that the graphics card is fine.

Here's a video on what I'm talking about.

I have a Dell Vostro 3450 running Windows 10 and I have a issue with my laptop screen (please see the attached photo)  .

This issue comes only when I use my laptop screen sometimes and it goes away after some time but when I connect it to a external monitor the screen display works perfectly. I tried taking a screenshot of the laptop screen when this issue happens but the screenshot doesn't show this issue. What may be the problem and can this issue be fixed ?

Answer:Display problem in Dell Vostro 3450 (Horizontal colored lines)

Based on the troubleshooting performed if the display is good on external screen then the systemboard works fine. Now that the issue is seen only with the laptop screen I would ask you to initiate the LCD BIST( Built in Self Test) on the system.
To initiate LCD BIST restart the system along with the FN key pressed or restart the system and keep tapping the D-Key. During the test solid colours will be displayed on the screen if the distortion is displayed during the test its confirmed that the screen is faulty.

Go to Start/Settings/Control Panel/Display and check that all your setting are correct. If they are then it may be either your graphics card or your monitor. To find which one is at fault test your system with another monitor.

Horizontal lines have started appearing on our Toshiba laptop (about four (4) years old). They start by shading (screen can still be seen through the lines, but very faintly) about one-quarter of the bottom of the screen and move slowly up until the screen is nearly covered.

Have tried everything including a complete hard drive erase and rewrite - nothing has worked.

I'm running XP, I started having horizontal "shadow" lines across my screen. Especially when using Word, or something with a light background and dark text lines. There is just a shadow all the way across the screen where the text(or dark object) is.

I bought a new Samsung 190s monitor. It still does it. Any clues?

Answer:horizontal lines across screen

If you already replaced the monitor, then your video adapter drivers are the next most likely suspect.

Locate the driver for your video adapter, whether on your motherboard cd, from the website or just let XP do it. Go into Device Manager, click on Video Adapter then remove. Reboot. XP will see your video adapter and more than likely install drivers. If you would rather use a different driver go back to your Video Adapter in Device Manager, highlight it and click on Properties>Update Driver and install the better driver from there.

Sometimes nothing appears on the screen just  flicker of Green & pink lines & black Screen After that.Where i should  to remove my battery  & place it ,to turn on my laptop in this case.
Problem is not related to software, if that was the case flicker should not be at dell logo screen.
But FYI my Graphic Card Drivers are already up to date.
I Guess the problem is at the hinges or with the monitor or maybe related to mother board itself.
when my laptop screen is less than 90 degree i can see few flicker,when it 90 degrees or more than that ,continuous flicker & black screen later as like monitor looses power nothing .

Any Other Information Required let me know.

Hi, I've been trying to fix my computer.  I have horizontal lines on the display/monitor in various colors.  I have already updated my drivers 'ati" and also updated my media card reader driver.  I have tried the various adjustments to my display with no results.  I believe I received a virus from a email.  I still have the email one was photo's the other part of it was a snip of music.  Any information would be highly appreciated.

Answer:Laptop Display has horizontal lines

With abuse, laptop monitors can do that. It pretty much means the connectors between the monitor and the laptop's motherboard.If you see these lines on the screen before windows loads, it's not a virus.How old is this laptop?

Hello! A week ago I bought the Dell 7567 and since the first day I've had it, the display shows a couple of horizontal lines across the top of the display. It doesn't seem to be an issue with the internal hardware because I have an external monitor connected to the laptop which does not show the lines but maybe I'm mistaken. Is this an issue with the laptop's panel itself or drivers? How do I resolve this issue?
I would love to hear a response, thank you
I have an image to show the horizontal lines: 

Answer:Horizontal Lines Across Laptop Display

Hi AimeeFritz,Thanks for posting.It's possible the problem lies in the LCD itself but here are some troubleshooting steps that may help.- First, connect an external monitor to the laptop then press the Windows key + P at the same time then select Duplicate display and see if the same problem will persist on the external display.- If you'll still see the horizontal lines on the external display that could mean the the problem is the GPU itself.- Do a clean install of the graphics card driver that may solve the issue.- Go to Device Manager and uninstall the graphics card driver.- Next, open Programs and Features then uninstall anything related to the graphics card.-Once that's done, download and install the latest driver from the manufacturer's site of the GPU.- Reboot the laptop once the latest driver has been installed.- After the reboot and if the same problem persists, then I would suggest contacting Dell Tech support in your country for a repair if it's still under the factory warranty.- Also, if the line does not appear on the external display, try to open the laptop and check the ribbon cable that connects the LCD to the motherboard. If it's still not working after reseating the ribbon cable, the last option would be to replace the LCD completely.

Answer:Random Horizontal Lines On Laptop

It sounds like a bad LCD panel, video cable or the connection. Power on the computer and keep tapping the F8 key then select Safe Mode with Networking. See if the problem appears on screen. You can also choose Low Resolution VGA mode (or something like that) from the F8 menu. That will help determine whether it's hardware or software related.

Would appreciate any feedback i could get on this. recently computers been freezing with horizontal lines. I thought this was just happening when trying to load an Internet page, but now it seems to be happening regardless of that.
When running in safe mode, there's no crash at all. I've tried running with low pixel / color definition in regular startup... Still crashes.
- Cleaned out dust / grime on board etc
- reapplied thermal grease
- updated all drivers
- system restore
- memcheck
It's an ms-7309 mobo, win xp home, 2g ram, plenty of memory, Athlon 64 x2 dualcore processor.
I'm thinking there's an issue with the onboard graphics card... Is that a safe assumption?

Answer:Xp freezing with horizontal lines on screen

One assumption is as good as another...the trick is to test whatever can be tested and see if it corrects or identifies the problem .
I would start with uninstalling the current video drivers, via device Manager, then rebooting and reinstalling the video drivers from the motherboard CD.

hi awais96,
Welcome to the Forums.

Since you've already tried the Intel graphics driver from the lenovo site but didn't work, can you consider uninstalling that and installing the driver directly from the Intel's site and observe.

Hey everyone... again I just wanted to ask about something I've been noticing with my LCD monitor. I see these faint, horizontal lines that run across the screen... they're really barely noticeable, but I know on my Windows log on screen with the blue background, I can see them pretty clearly.I just put in a new video card a couple weeks ago. I'm not sure if the lines have been there since putting in the new video card or if they started some time after putting it in, but I know they weren't there with my old video card.Something that I thought might be contributing to this, though - my video card doesn't have a VGA port. I had to get a DVI-VGA adapter for it so I could plug my monitor in. Do you think this could be causing the faint lines? I've checked and reseated the cable running both to the monitor and to the card, but the lines still appear.It's really not a big deal for me - like I said, the lines are barely noticeable, but I just want to make sure that something more serious isn't going on as my luck with computers is pretty awful lol I've searched around online and can't really find anything related to this issue, so I wanted to check with you guys and see if you had any ideas, suggestions, etc Thanks in advance for any help!Monitor: ViewSonic Optiquest Q19wbVideo Card: ATI Radeon HD 5670Oh, and my temps are and have been fine.

Hello,I just bought a new Pavilion dv6 (LW272UA#ABC) ten days ago and I've noticed that after the screen turns off due to inactivity, or because I close the lid to let the notebook sleep, two to three horizontal white lines flicker on and off  at the top of the screen every few seconds until I restart the computer. Should I be worried ? Should I ask for a replacement from the store tomorrow or should I wait to see if the problem becomes worse or until HP/NVIDIA release a driver update ?

Answer:Horizontal lines a cross screen!!!


You might have a bad power inverter board. This is the board that powers back light to the lcd.


This is what it sounds like.. Check your RAM. You might need to reset it or it could be bad. If you have two sticks of ram in your machine you might want to try booting your machine with just one of the sticks and then swap it with the other if the problem persists. Remember that you can only touch the RAM when the machine is off... Otherwise you could damage you machine by shorting it.

You can connect the laptop to an external display to check if the same line appears.
I would also encourage you to do a back up plan as early as today while the warranty of your machine is up.
With all other issues happening, it would be better to call in technical support and have this reported.

Hi, apologies if i am posting in the wrong section, it is my first post.

I start up my computer, the bios runs as normal detecting drives etc. then it gets to "loading operating system..", from here it either stays that way or changes to a screen with horizontal blue lines and if you wait a little longer still, other colored lines appear aside these blue lines. This all happens at the top of the monitor.
I have tried to restart my PC several times and the same thing happens with these lines. I have also tried changing monitors, unplugging all inputs. Nothing.

IF there is any extra details you want, just ask.

What is the problem here, and what is the easiest way to fix it?

Answer:On boot, horizontal blue lines. No startup.

Hello guppyfish and welcome to Seven Forums.

When a computer fails to start it can be software related (perhaps a damaged or corrupt operating system) or hardware related (a failing hard drive, video card, etc.) Another posibility is the computer became infected with some kind of malware that has damaged or corrupted the boot files. It can be very time consuming to try to isolate the problem.

Can you boot your computer into Safe Mode by using Advanced Boot Options? If yes, you may be able to roll back your computer to a date/time before the problem began with a restore point.

Safe Mode

System Restore

If there are damaged or corrupt system files you may be able to repair them by running a system file checker scan from an elevated command prompt (option two.) If problems are found, run the scan 3 times and reboot your computer after each scan.

SFC /SCANNOW Command - System File Checker

If the problem continues, one of the Forum experts prepared this troubleshooting guide. Many people have been able to fix their computer issues by following the steps exactly.

The flickering is intermittent, it can be gone for weeks or longer without a flicker. Then it will develop and worsen over time until I can’t even see the screen to shut down the computer. It doesn’t seem to matter to the flickering if the computer has been on for a minute or a day.

When I plug in an external monitor, it has perfect display, even when the laptop monitor is unreadable.

While playing a DVD on ‘Intervideo WinDVD 4’, it displayed perfectly if I didn’t open the player window to full-screen. Once I enlarged the player window past a certain point it would go from clear to (not just lines) huge blocks of rapidly scrolling graphical chunks. Totally scrambled. Before this last use of the player, I could maximize the player window without problems.

I have a hp dv6000 running vista that has recently put a lot of horizontal lines in the monitor. They are lines that are discolored and make it very hard to read, like it's every other line of resolution. I have raised my font to get through a project, but need to get this fixed or get a new laptop. A local repair shop said it was probably the monitor ribbon cable, that's where they would start. They wanted around one hundred dollars for the cable and time, and it may not solve the problem. My thought, is that the cable would be an intermittent problem, power would be black screen, and vid card would be black screen. The laptop runs as usual, its just missing half the info on the monitor. Does anyone have any suggestions or thoughts? The laptop is disassembled because I was going to order a new LCD for it, but came here before clicking on buy.

Answer:Solved: Laptop monitor has horizontal lines

Hi and welcome to TSG.

Any repair place worth its salt should have a look at the machine and do some tests (which may cost an hour of time) before suggesting a replacement part, which may not even be the faulty component.

If you can get the laptop back together and do a simple test (below) it can help to narrow down where the fault lies. It could be the LCD, the Graphics Card, RAM or a cable / connector, drivers or something else, hard to say at this point.

Plug the laptop into an external screen and see if the problem occurs there. If it doesn't then it could be the LCD itself or a cable / connector between the GPU and LCD. If the problem occurs on the external monitor it is more likely to be a problem with the GPU itself which would likely require the entire motherboard being replaced.

My system:
DELL XPS 15 Laptop 9530

About three weeks after I purchased this machine, flickering horizontal lines began appearing across the screen.  They are transparent, a little less than 1cm in height and traverse the whole width of the screen.  Each line is separated from the next by about a quarter of the screen height.  There are three of them currently and they always appear at the same height on the screen.  They are barely noticeable on a white background but can be prominent and annoying on dark backgrounds or photos etc. 
Have run all the diagnostic protocols on the DELL website – everything working perfectly. 
Not sure whether this is a hardware or software problem.
Any help appreciated.

Hi ,
Thank you for writing to the Dell Community Forum .
In this case do confirm if you have performed these steps and advise ,
*Have you checked the system's performance in safe mode ,because safe mode uses very minimal drivers and graphics if the issue is seen in safe mode then its a hardware issue.
*What happens when an external monitor is connected to the system ?If the lines are not seen on the external screen then the system board works fine  .
*Have you tried to initiate LCD BIST ( by restarting the system and pressing the D-Key on startup ,solid colours should be visible clearly if the test passes )
*May I know how were the diagnostics initiated on the system.
Hoping to hear from you soon with the service tag of the system (send it via private message only ) so that I can check the specifications of the system .

HI guys,

I don't have the model on me now, but recently I worked on a Compaq Desktop computer. At random times (could be any program open), it would go to a grey screen with weird horizontal lines. I upgraded the video drivers, ran a video stress test and it went over 2 hours with no problems.

The customer just reported to me that it happened again so I am thinking that maybe it is a faulty motherboard (video built onto motherboard). What do you guys think? I didn't wanna give the customer the run around saying "Let's try 1) putting in a new video card then 2) lets try reformatting and lastly 3) lets replace the motherboard)"


Answer:Compaq going to a grey screen with horizontal lines

Sounds like a possible bad connection at the monitor
or video card.
Might try disconnecting and reconnecting the video cable
or just try a replacement.

I recently installed Windows 7 Ultimate a week ago and in the past two days, when I have started my laptop up, after 10 minutes or so, I suddenly get horizontal coloured lines in blocks on my screen (screen goes blue or black with coloured lines flickering all over it), or it flickers and goes white.

I have no choice but to force it to shut down and then it usually takes 3 to 4 forced shutdowns before it works normally with no problems. It was a clean install and I have updated the display driver, but still have the same problem. The guy who installed Windows 7 won't get back to me, so I can't talk with him to see if he knows what happened.

It?s a satellite A350 laptop, and is only 7 months old. I had no problem with Vista, so it seems to me as if it's something to do with Windows 7. Can I still keep Windows 7 and stop this problem or do I have to revert back to Vista and if so how?

My computer didn't come with any recovery disks etc. If anyone has the same problem or knows how to fix it please let me know, I need my laptop for exams so the sooner I get this fixed the better.

Answer:Windows 7 causes screen problems - horizontal lines

My guess would be some corrupt display drivers. What model do you have? Make sure you install the latest drivers for you OS.

It's either that, or you graphics card is overheating.

Hello All

I have a dual screen setup, with my desktop extended to a second monitor. A week or so after updating windows 10 with the creators update my dual screen set up is experiencing a large horizontal line traveling up one of my displays with shaking below. I have attached an image.
This first happened on my primary display (29" Asus connect with display port). After rebooting the tearing then moved over to my secondary display where it has remained for the last week intermittently. (Samsung 22" connected with a VGA to DVI adapter). Both Monitors are connected to my ATI R9 270.

I have ruled out the display hardware as this issue goes away in safe mode. If I set my computer to only use one display either the 22" or 29", the issue is gone. I have also connected to another computer (mac book pro) and the tearing does not persist.

Other things I have tried:

RebootShut downPulled power cords from monitors and pc for 30 minutesUpdate graphics card driverReinstall graphic card driverTry different connectorsUninstall display device in hardware manager

Any and all help is appreciated as this one is really driving my nuts!

Upon starting the laptop a white screen appears with horizontal lines (NOT VERTICAL). This seems to freeze on this screen unless I move the screen back and forwards or press the bezel on either side at the bottom. So I have done all the obvious things including updating all drivers, cleaning out any accumulated debris, pulling the screen apart to check the cables are OK and all appears to be good. Now this doesn't happen every time and the LCD seems to work perfectly with no other problems that are obvious so don't think the screen is cactus. About to see if I can check the GPU is seated properly. Any suggestions are much appreciated but please don't suggest things like malware as this has all been checked out and the laptop runs smoothly in every other respect. I am wondering if it is something to do with the bios not properly initiating the GPU but its just a guess?

Hello All

I have a dual screen setup, with my desktop extended to a second monitor. A week or so after updating windows 10 with the creators update my dual screen set up is experiencing a large horizontal line traveling up one of my displays with shaking below. I have attached an image.
This first happened on my primary display (29" Asus connect with display port). After rebooting the tearing then moved over to my secondary display where it has remained for the last week intermittently. (Samsung 22" connected with a VGA to DVI adapter). Both Monitors are connected to my ATI R9 270.

I have ruled out the display hardware as this issue goes away in safe mode. If I set my computer to only use one display either the 22" or 29", the issue is gone. I have also connected to another computer (mac book pro) and the tearing does not persist.

Other things I have tried:

RebootShut downPulled power cords from monitors and pc for 30 minutesUpdate graphics card driverReinstall graphic card driverTry different connectorsUninstall display device in hardware manager

Any and all help is appreciated as this one is really driving my nuts!

I believe you need a new screen.  It looks like bad connections on the contact tape.

To resolve this, you need access to the inside of your unit and reset/clean the contacts of the connectors from and to your display panel.

For the past few weeks my laptop (Fujitsu) screen has been flashing black with white horizontal lines from time to time. This lasted 2-3 seconds until I hit any key or the mouse and it stopped. Today however , as I was online it flashed black with the lines and stayed that way for hours despite my trying to re-start , unplugging etc... Then I turn it on twenty minutes ago and it's back to normal.Anyone know what could be wrong?

Hi, I have a HP Pavilion 24-B015A 24" Touchscreen All-in-One Desktop PC, which I have only had for about a month. I noticed a few days ago this perfectly straight horizontal line at the top of the screen that looks like little X's/crosses. I can also see them very faintly when the screen is on but also when the screen is turned off - which means it mustn't be a graphics problem. I just wanted to know what the exact issue/cause of this is as I couldn't find any information about it online. Please see attached image:

Hi Amrradwan , 
Welcome to the Community Forums. 
Since the issue would be intermittent , next time that it would happen to best take a picture of the image and likewise try to connect it with an external monitor to check if the same issue would appear. 
I would stilll recommend that you call in this issue for documentation purpose and further reference in the future , You may consult tech support for an action plan for this event . 
Update us how things go.

So recently my computer has been experiencing some issues. Black horizontal lines have been showing up all over the screen. At first they were intermittent but now they seems to be happening more often and it's getting worse. Could this be an issue with the graphics card or the graphics driver? The lines do not show up in a screenshot if that says anything. I have a Lenovo yoga 11s with windows 10 and have only had it for 2 years. I would really like not to have to replace my computer because of this.

Answer:Flickering Black Horizontal Lines Across Screen?

if you ve just upgraded to win10 visit the Lenovo support site to check whether driver updates are available. same also for the graphics card.

Purchased an open box Y70 Touch from Best Buy last week. I'm getting occassional thin horizontal lines flickering across the screen. It's only intermittent and so far I'm not able to figure out what triggers it. Until this morning, I had only see it happen when plugged in, but it happened for about 30 seconds on battery a little while ago too.  I can return the computer to Best Buy for another week, but I really don't want to because I love this computer and got a great deal on it because it was an open box. Is there any possibility this is a software or driver issue that I can resolve myself?  The problem looks very similar to this:

Answer:Y70 thin horizontal lines flicker across screen

This is an issue with the connection, I must re-set my connection once every month because it slowly becomes off a bit.. here is a video you guys here can check out.. it has nothing to do with software, updates cannot fix this. can thank me later lenovo for shining light on this topic, but when you do find the reason (which I am giving a fix for) I want you to tell them yourselves that we must re-seat the connection.This is a great example to back up my fix, Have you ever sent in your laptop for repair with this issue? did it come back "fixed" and then a few weeks later same symptoms appeared?Lenovo techs opened up your laptop and saw the connection was off a bit and so they re-seat it, but yet the connection never holds. Lenvovo needs to find a new clip to keep it in secure.. so thats what you should do lenovo hint [email protected] please follow the video provided and please report back here when its fixed , if you have any quesions just post here

Horizontal lines appear at the top of my A100 after using the picture preview slideshow or any photoshop programme. They can be removed when the desktop picture is changed.

The laptop was purchased in April this year. Geoff

Answer:Horizontal lines at top of screen - Satellite A100

From your post the only plausible explaination is that you don't have large VRAM wich means that the refreash rate is relatively low. Althow there coul be other problems, but these is the only conclusion I can draw from your topic.

Hi,Dell Dimension 4100Windows MePentium III128 MB RAM80 GB hard driveOpitiquest Q9 flat panel displayATI Rage 128 Pro display adapterAbout one week ago, I noticed that short horizontal lines started appearing on my Dell M990 monitor screen. When I moved the cursor around, little white lines appeared as well. I bought a new Optiquest Q9 flat panel display to replace my old monitor, but the problem persists. When I reboot the computer the problem goes away for a while but then reoccurs. Half the time the problem does not occur at all after a reboot. I think there may be a problem with the ATI Rage 128 Pro display adapter but I'm not sure. Any advice would be greatly appreciated. Thank you!

Answer:Short horizontal lines on monitor screen

Display adapter problem for sure.  Start by trying the latest drivers from the manufacturer's web site.  If this does not cure your problem, you may need to replace the card.

I have a Toshiba Equium P200D-139 laptop and the screen stopped working.
It lights up but the display consists of vertical lines, which slowly fade into a black screen.

I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.
After trying a new inverter with no success, I bought another second hand screen.

However, the new screen has the exact same problem with the ?horizonal lines? display.
Just occassionally, I catch a glimpse of a partial Vista screensaver for a split second but then its back to black. I?m not a technophobe, so any info would be very much appreciated.

Please help, as it is driving me up the wall!

>I tried it on an external monitor and it worked fine, (so presumably cannot be a faulty graphics card/motherboard). So, I thought it was likely to be either be the inverter or the screen itself.

Right. I think the issue is related to the display

>However, the new screen has the exact same problem with the ?horizonal lines? display.
Well, it could be possible that the second screen is faulty too? if you bought this as second hand part then it could be possible that you bought a screen which does not work properly.

What to say; it?s difficult to say what you should do as next. Buying a new screen and to check this again? Well, I think I would visit the next computer repair store and would ask for checking the display.
I think this is the best solution in your case?

Answer:I keep getting weird horizontal and vertical lines on my screen

Hello Jinx23,
If this card has been in your system for a while, not a new install, then your GPU is going bad.  You might try updating drivers for the GPU and testing the memory, but it looks like a bad GPU chip.
No changes to your monitor? No chance the monitor cable from the unit is loose, checked the connections on both ends?
Run the Dell Diagnostics for hardware, on F12 Boot Sequence, drop down to Diagnostics, you can check the memtest, prepost, etc, but you need to drop down and do a hardware test or a system tree test.

When the system is turned on the screen is normal for about 10-15 seconds then the horazontal colored lines slowly take over the screen until it is just a blur after about 60-90 seconds.   I can use the HDMI output to view on my tv with no issues it is only on the laptop screen itself. I am capable of canging a screen if this is the issue but how can I detrmine that is the exact issue and ther is not something else wrong? This is my girl friends computer and I was informed that a can of soda punctured in the same bag as the computer so it did get a small amount of mosture on it.   I do not know how much and everything else is working just fine on it. Thanks in advance for any assistance. John

We're having a problem with our HP Pavilion laptop running Windows Vista where it crashes and all you see are horizontal lines on the screen. Below is a list of things we've tried to troubleshoot what the problem is, can anyone interpret from this list what the problem might be or have anything else we can try to narrow the problem down?

- crashes on battery and AC adapter
- updated bios, drivers, ran antivirus, downloaded windows updates, did system restore, still crashes
- when it crashes, music freezes as well, so it's not just video card
- didn't crash when it booted and ran from norton antivirus CD
- rebooted and ran linux from CD, crashed on linux
- removed/replaced battery and RAM, still crashes
- hard disk check completed without problems

I see horizontal green lines whenever i try to open my NVIDIA control panel. it goes away after i close the control panel or overlap it while opening a different dialog box. I tried updating my driver, but it just wont work. I have a screenshot of how the lines look like. (NOTE:the lines are only the problem, the words appear so because i have reduced the size of the picture) I use windows XP with built in NVIDIA geforce7100/nforce630! graphics.

After traveling, I took out laptop, powered it up and HP logo screen did not come up but white and colored static horizontal lines were floating/fluctuating across entire screen. I searched for an answer on another laptop and did a hard reset which happened to work. But after shutting it down, traveling back home and trying to power up again, it happened again but hard reset will not work now.
