XPS 13 9360 vs Dynamic Contrast/Brightness

Question: XPS 13 9360 vs Dynamic Contrast/Brightness

Recently I bought XPS 13 9360. I'm strongly annoyed by Dynamic Contrast/Brightness in the screen.
I downloaded "Firmware Update for enabling or disabling Dynamic Brightness Control" from link. After starting the program, I got an error

Preferred Solution: XPS 13 9360 vs Dynamic Contrast/Brightness

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.)

Hi, everybody,I'm very happy with my P70 in general, but there are a few things that really drive me mad, the most annoying one being the dynamic contrast or brightness control that I just cannot get to stop interfering with my work. The problem is that the brightness and contrast become WAY WORSE whenever the screen is predominantly dark -- which is all the time, because I'm using a software IDE with a dark color scheme. And it's really not my imagination, because you can literally see colors blooming and brightness getting up when I change to something more bright, say my browser window with the Lenovo forum page.I had had this issue a few weeks ago, but it vanished after updating all Lenovo software and the BIOS last week. However, now I enabled the "Schwellenwert für Akkuladung" (~ threshold value for battery charging) and now all of a sudden the problem is back again and remains even when I disable the threshold value setting again...I have tried different power settings (in Windows) and deactivated basically any option that even remotely resembles the terms "dynamic", "smart" or "adaptive". Since I'm running with the discrete Nvidia graphics card (Intel card deactivated in BIOS) and suspected it might have something to do with a "smart" Intel technology, I even reactivated the Intel card, updated the driver and some Intel software, deactivated everything I could find, restarted a few times, then deactivated the card and the BIOS again, uninstalled Intel software -- but...

My laptop is a y560 model; I got it about a week ago. I know that the monitor settings and whatnot have this 'dynamic contrast' thing going on, which apparently makes the screen dim/brighten whenever it deems the time to do it, DESPITE whatever power settings you have that say to not dim the screen, ever. I'm sure there are people out there who really enjoy this setting, but it's frankly one of the most annoying things that I have ever experienced.  I've looked over the manual and looked over internet searches and a bit through the controls that I can easily find, and I am still unable to figure out how to turn this 'dynamic contrast' off, permanently. I don't want it to happen anymore. I'm all for setting the screen to dim during certain POWER situations, but having it just randomly start to dim while I'm in the middle of reading/typing/watching something is rather, rather annoying.  How do I get to the settings that will turn this feature off? And once there, how do I turn it off?

For the onboard monitor on an X230. (ips) latest intel drivers. When i noticed it, i checked all video settings and found it had "dynamic contrast" enabled.

I purchased a U510 back in August for school because the display on my old laptop had died and it was from the stone age, so it was time for a new one. I love the U510 with a few exceptions the main one being that there is a Dynamic Contrast Ratio function built into the display in some way or another, this is often found in modern monitors and easily disabled through their On-Screen Controls. However my laptop does not have OSC for the display, as far as I can tell, and I have no way of getting in an disabling this function. Is there anyone that knows how I can disable it, it's driving me absolutely nuts!No, it is not the adaptive contrast/brightness being monitored from the camera.No, it is not an option within the Intel 4000 Graphics settings. I've spent HOURS trying to resolve this. The other thing is the low battery beep, please allow us to disable it with a bios update, thanks.

I cannot disable Dynamic Contrast on this laptop, be I running on DC or AC power:

Dynamic Contrast: the backlight on the monitor changes brightness based on the graphics shown on-screen; lots of dark pixels lead to backlight dimming, lots of bright pixels lead to backlight brightening. This happens continuously, when switching windows or applications, when manipulating CAD models, when scrolling through web pages, etc.

(This is not to be confused with Adaptive Brightness, which changes the backlight brightness based on the brightness of the external environment of the laptop, i.e., dark room vs. high noon outside. I have successfully disabled Adaptive Brightness.)

Demonstration: I'm displaying a mostly black web page, maximized. I have a large white Notepad window that I can drag around to add lots of white pixels to the screen. To not let my phone's auto brightness/contrast muddy the perceived behavior, I have zoomed into the top left corner & I am dragging the Notepad window up & down to essentially turn the right half of the monitor white. When Notepad is up & the monitor is half white, the backlight brightness increases dramatically, distractingly changing the dark pixels because of pixels on the other side of the screen changing brightness.

Find out what the maxium refresh your monitor supports and set your refresh setting to it and that will produce less eye strain.

Good morning:

I have a Dell computer with windows XP. The external controls for brightness and contrast on my monitor are maxed out. I remembered from windows 98 that there is a program one can go into to further adjust these settings. Does XP have such a feature? If so how do I go about finding that and getting into this program? I would appreciate any help that someone might give me.

Thanks, larry_373

Answer:Brightness and contrast controls.

Hi larry373!

Check that you have the lastest driver for your video card.
Also see if there is any software on the internet that may be specific to your monitor.

Depending on the manfacturer of your card, you may be able to access extra video settings as follows;

Right-Click a blank area of the Desktop.
Select 'Properties'
Click 'Settings'
Click 'Advanced'

I believe some video cards also extend the "Display" Control Panel with additional features.

Umm, it's hard to explain the problem thats happening with my monitor
As I turned it on one day, the brightness Contrast menu, on my dell demension 4700, keeps going up and down. Even as I type this down, it's in the middle of the screen, and it's impossible to see whats behind it. I've umplugged and replugged the moniter in. Restarted my computer, and holded down all off the buttons, but it seems never to go away. It occassionally leaves, sometimes, but it comes back randomly. I can no longer visit the dell moniter menu. and even sometimes, it takes away the contrast making me screen pitch black, but it's still on. But it comes back as randomly as it happened. Please help me .

I thought this would be in software section, but it's hardware for the most, since if I take my computer umplugged this moniter keeps doing the same thing.

Here's the video, so you can see what I'm talking about. Basically, XPS 13 9360 QHD, has this issue when in a dimly light room, the brightness will be automatically set to the max, and won't be changed by either bios settings (you can adjust brightness level there for battery/AC), latest driver settings, or by keyboard keys.

It'd work normally, but then it'd start going bonkers, but then it'd go back to functioning normal.
Or just stay at max brightness.
I tried disabling DBC, installing latest graphics driver from Dell website, or Intel website using this method, installing latest bios, and other recommended drivers, disabling sensor monitoring service in "services.msc", didn't help.

If the power supply is cut off for about 5 minutes the problem is fixed but it always comes back. problem didnt occur before i got this Gatway EV500 moniter

Answer:Moniter contrast/brightness problems

Can be a lot things.

The best thing to do first is swap in another known to be good monitor. Put that monitor on another PC, see if the problems continue, try to determine which has the underlying problem or is it something more related to them working as a pair.

It can be bad pins in a connecting video cable or a connector that is not fully seated or something to do with the cable itself, like being too long, excessive twisted or looped, etc. Try to run the cable thru your fingers and watch for a dramatic change in the screen. Could have a nicked cable or broken wire. You might be kicking it with your feet. Get it away from any power cords.

Try pulling the plug on the monitor to give it a hard Reset, wait about a minute and repower it.

Try degaussing the screen.

The fact the color purity drifts tends to point to a video feed quality type problem. Can try tweaking the video card settings.

Also check around for any interfering magnetic devices, other monitors to close, speakers, other electrical appliances.

Usually this is not a hardware type problem in the monitor itself. Would more likely be the video card if it is hardware related.

Virus's /spyware can't affect your monitor's OSD from popping up. That is controlled purely by the monitor. Probably, wither the OSD button is stuck pressed and comes up every once in a while, or there is some dirt in the button, producing the same effect.

Answer:Auto Contrast/Brightness correction?

Brightness and contrast likely will not be automatic nor a feature of your video card. Depending what program you run you an adjust these levels, an example would be call of duty. You will also be able to find these settings in your control panel. There is one other way to gain access to your brightness and contrast, and that is the manual settings on your screen.

The second is through the control panel for your graphics card which should be accessible by right clicking on the desktop. If it isn't there is should be in the Start menu, that or you don't have the driver installed and are running on the default driver installed by Windows.

Try a "restore point" to a time when it worked. See vista's help and support pages for info on that. If that fails then maybe the keyboard is bad.1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

Thanks in advance

Answer:Cannot change contrast, brightness etc. on Satellite Pro 4600. Help please.

Hi Andrea,

normally you could change this settigs in the control panel, but to explain the way to change it would be nice to know which OS you have installed.

If you have the perinstalled Os it could be that you have Win2000.


Go to control panel - Display - Advanced and then you could choose between Television, Color or Video.

The Brightess could be changed in the Power Saver because the brightness depends on your power setting.
In battery mode higher brightness could decrease your battery power!!!

Bye Bob

Answer:Satellite Pro 440cdx - How can i alter the brightness or contrast


The display brightness can be changed pressing the FN + F6 or FN + F7 button combination.
The contrast cannot be changed on notebooks displays? this is set automatically.

But if it?s very difficult to see anything on the display, then a FL inverter might be defect.
The fl inverter is a tiny part which controls the display brightness.
Maybe it?s need to be replaced.

When I turn my laptop on and when the desktop comes on, the screen is low contrast/mid-brightness.
It remains like this for about 10 seconds and then it flickers and changes to a high contrast/high brightness screen.

I want to get my screen looking like how it does for the first 10 seconds when the desktop comes on. My screen at the moment is very high contrast which makes it difficult to look at some photos (particularly ones taken indoors like in a club). As far as I know, there is no button to adjust contrast on the laptop.

I have tried to play with the brightness button but it doesn't help. I've also tried display settings in control panel and also tried to right click the desktop which gets me to the graphics properties. But I can't get that low contrast/mid-brightness screen I first see.

I recall vaguely when I first setting up my computer that there was an option for high/low contrast and if i remember correctly, i chose high contrast which on hindsight was a mistake. how do i go back and change this.

i've spoken to toshiba, not much of help. they've suggested i reinstall the display driver? how do i go about doing this?

and does this sound like a graphics card problem?

cheers :)

I?m not sure if you are meaning the same by display contrast/min brightness but usually you could change the display brightness using the button combination FN+F6 or FN+F7

This key combination is present for all Toshiba notebooks and you could find the info in user manual as well.

Answer:Solved: HP laptop screen brightness & contrast

There's usually a key combination using the Function key and an F1-F12 key to increase the brightness and a different F1-F12 key to decrease it. Have a look at the F keys,for a 'sun' icon.

Usually the problem is brightness gets lower ! If it is definitely increasing there could be a hardware problem.

Answer:How to adjust Brightness & Contrast for HP Omni 120-1125.

I'm not aware of any buttons to change the display settings on this computer. However, I think I can help you find Hardware and Sound in the Control Panel. Hopefully all you will need to do is change the "View by" setting. I suspect that right now it is set to one of the icon views. Open the Control Panel, and in the top right corner click the drop-down menu next to "View by:".Select "Category."You should now see a list of categories, including Hardware and Sound.  And now hopefully the steps I posted before will work for you. Please let me know if you run into any trouble.

I bought this PC recently and have been very pleased with it. Adapting to Windows 8 was quick and effortless for me, and I have very few qualms about it.

However, I shut down last night and when I booted up this morning, my display is different than it was before. In fact, it's quite confusion. Some areas are darker than they should be, and other areas are washed out or too light. This points it to being that somehow my contrast has changed - but how? I can find no contrast controls anywhere. There are no buttons my PC for these settings - as this is an all-in-one PC. The brightness slider changes nothing.

Some things look "normal" while other things are just too saturated, too washed out, or too contrasted.

Is there a way to set it back to default? A way to change my contrast? I'm an artist and this change in screen depth is unsettling for me - as in all calibration tests, I can see the difference between shades of black, but white is simply... white. There are no shades of white on this screen, now.

Edit: It's especially anything yellow. There is very little shading between colors of yellow right now. On my color slider, everywhere there's a hint of yellow is just... yellow, with no gradual changes into the next color(s).

Edit again: I improved it only a little by turning the gamma down slightly and playing with color sliders, but it's still far from what it should be. I have no idea what changed my settings or how to get it back exactly as it was.

Dear all,

As stated in subject, the laptop in question is a recent Skylake XPS 13 9350 FHD. This is a wonderful laptop with one major defect ("feature"): content adaptive brightness/contrast.
My main use-case is development under Linux, and it becomes very irritating when switching between dark terminals and bright websites, e.g. when reading documentation.
There are several other websites, forum threads etc., that already exist on this issue, with unsatisfactory answers.
Therefore I would like to ask here how to turn this "feature" off; an answer of "this is not possible" will not be accepted, as I am aware that this is possible in the worst case by updating the firmware (with success stories on the QHD models).

Many thanks!

Answer:XPS 13 9350 FHD Content Adaptive Brightness/Contrast Turn Off

an answer of "this is not possible" will not be accepted, as I am aware that this is possible in the worst case by updating the firmware (with success stories on the QHD models)

Sorry, that is the answer you will get. Only the QHD models are fixable with a firmware update (provided from dell's download center). They have confirmed that the adaptive brightness on the FHD screens lacks this solution and from what i recall they are not actively working on trying to find a fix for the FHD as the adaptive brightness is "working as intended" at least.

I am a visually impaired user and I'm thinking of purchasing the Satellite L550-113, but before I do that I need to be sure that the screen brightness/contrast can be adjusted very easily, preferably via hardware controls as opposed to via the control panel. I also need to be sure that one can make the screen quite dull (i.e. too dull for a non-disabled user).

Could anyone give advice on how to adjust the screen contrast and brightness on the Toshiba L550-113? Also, does the screen have a glossy or matt finish?

Any general information on the quality and ease of use of the screen will be extremely useful and highly appreciated! Thank you.

Answer:Adjusting screen brightness and contrast on Satellite L550-113

Hi mate!

Yes, the screen brightness can easily adjust via FN keys. You have to press FN+F7 to increase the screen brightness and FN+F6 to reduce the screen brightness. Furthermore in Vista power management you can also adjust the screen brightness and save the settings for different power profiles and on batter or on power mode.

As far as I know Satellite L550 has a gloss finish screen as other Satellite notebooks.

I hope I could help you a little bit! :)

Please note that usually you can change the display brightness using the FN+F6 or FN+F7 buttons.
If you want to change the settings for contrast, color, etc? you have to check your graphic card properties.

But to be honest, I?ve never changed these settings because it was not necessary for me.
Everything is controlled automatically by graphic driver.

I have set adaptive brightness to off and also turned off Intel's Display Power Saving Technology. But I noticed that the entire screen changes brightness (or contrast) while I switch between 2 windows (pictures). Is this normal?

I posted a video so you can see the problem (or is it?) in action

If you also want to test it out yourself, here are the images used while switching windows.


I also want to mention another issue I'm having (which I think is related to the one above, that's why I'm worried). I purchased an Asus X454LD last 5/5, and for some reason it keeps on flickering static. Sometimes not entirely on the screen, and not an opaque static but a translucent one that overlays with the work area. Then I got the unit replaced with a new one last 5/10 and the issue's still there. There are no specific programs or time that triggers this problem, it just happens. I even reinstalled both the Intel HD graphics driver and the dedicated 820m driver. I posted a video that shows the problem in action as well.

Hi folks - This is my first Lenovo forum submission and I will do my best to describe the problem with my laptops' video/display. I'm all ears for your suggestions. *Issue* The display would occassionally dip down in brightness/contrast then change up to a very HIGH contrast level on its own. The desktop icons, background image & browser images become un-sightly bright BEYOND your normal Lenovo Power Manager settings. All the white hues turn even brighter, and some hues are NOT viewable at all on certain backdrops. Usually, it resolves itself after several minutes.Then it's business as usual. I do not believe it has anything to do with the Power Manager settings (e.g. Idle Time, brightness control, Battery vs AC power, etc.). It simply occurs on it's own then disappears. A reboot can help and so does closing the lid and re-logging into Windows. But who wants to practice that technique after paying over $1600 for a professional grade business laptop? I found only ONE forum message that came close to reporting the problem, found in the body of a message and NOT as a subject (SEARCH:  "screen image fades as if you lose contrast") Frequency ? - Atleast 4 times a month for the past 3-4 months since my purchase in summer 2010. OS: Windows 7 (64 bit)CPU: i5-540M 2.53GHZRAM: 4 GBLaptop model: T-510Laptop Product ID: 4313CTOGraphics: 15.6 HD+Battery: 6-cell Purchase date: summer 2010

Using the following link's content to gauge my contrast level on my brand-new x230t, my computer's vaunted display is actually very inadequate. I can't distinguish either end of the spectrum, no matter how I adjust my contrast using the Intel graphics and media control panel (why it won't let me set it any lower than "40," is puzzling to me). I have a former ASUS G50, with the same display (albeit it larger, with a Nvidia graphics card), as well as a Droid Razr and an ASUS Transformer Prime with smaller displays (just slightly) . There is another monitor in my house with again, the same display resolution, running on another computer with another driver, and the point I am getting to with all this is: I haven't seen a display with such contrast issues in a long time. Following is a desktop screenshot of what shipped of the "default" settings for contrast, brightness, hue, saturation, etc., in addition to a picture of what the background looks like on my other four displays (and does, on four other different displays) There is no reason a mobile phone should have a better contrast, brightness, hue, etc, than a $2,000 dollars rig.

I've had a lot of problems with this computer's graphics and stuff being way too dark despite my monitor settings(that I set with the little wheel thingy on the monitor) of brightness and contrast being all the way. I could not figure out how to make the picture better after a lot of searching, but I tried again recently and found where to go (see first pic).

So I adjusted that stuff until I got it good. Then I saved it and checked the apply at startup box. But the problem is, it wouldn't apply the settings at startup. They were saved and everything and the box would still be checked, but the picture wasn't what I saved it as. All I'd have to do though is just select what I saved from the drop-down box but shouldn't it already be applied all the time? I'm guessing I'll have to adjust something in my System Config Utility in System Information but I dunno so I'm asking you.

I got a XPS13 9360 with Ubuntu Linux last week and after some work this days I noticed some weird behaviour on brightness and contrast, more evident when using at the same time an external monitor. 

After some research I discovered there was a "feature" I cannot disable called "Dynamic Brightness Control" embebed on screen firmware.  I called technical support and they suggested me to format the laptop to install a Windows (illegal copy, I presume, as I haven't a legal one) and then reinstall Ubuntu with all my data. Looks like a joke but is not. 

So I've spent some hours trying to set up a Live Bootable USB drive with Windows just to execute this utility that seems to be the only way to disable this awful feature:

I think the best place to enable or disable the "feature" (let me quote that way because it's the worst thing i've ever seen: get up the bightness when there is more bright?. Do you want to burn my eyes at night?) would be on BIOS. But I've seen complaints for more than 2 years and nothing... Read more

So I've searched around and found various fixes to this and none of them seem to work when BOTH 750M GPU's are installed in the machine and it's on battery power. I need to find a solution to this or I'll have to return this laptop because this is incredibly annoying to have this problem every time I unplug this thing from the wall.The Problem:When BOTH 750M's are installed in the machine, the Intel Graphics HD software ceases to function and the auto backlight takes over and makes adjustments according to what you're seeing on the screen. An example is if you have a dark wallpaper, this "feature" scales the brightness way down and does the opposite for a bright wallpaper. So if I have a dark wallpaper and then open a windows explorer window the brightness scales way up because the background is white and when I close that way it scales way down because the background is dark again. I'm not sure about everyone else but this drives me insane. What I've done so far:- Uninstalled all drivers for NVIDIA- Removed the 2nd GPU- Installed Intel's HD graphics driver and turned off the auto backlight under the "Power" area. <-- At this point with 1 750M and the Intel chip, Optimus works and the problem is gone.- Re-installed the 2nd 750M and powered up <-- At this point the auto backlight still isn't functioning which is exactly what I want to happen.- Rebooted the laptop and when it turns on the auto backlight is back, SLI is working, the Intel HD graphics program...

UPDATE:If I open the NVIDIA Control Panel and Disable/Enable SLI, the problem is instantly gone until I reboot the computer. It doesn't even seem to matter if I am turning SLI On/Off, once that apply button is activated and you can click it, the problem is gone. - SO yea....that's getting somewhere I guess.

 I am having a ton of issues with the on screen brightness display and the brightness controls in general on my windows 7 e545.  The problem seems to happen anytime I open the computer up from sleep mode.  In order to regain brightness control I have to reboot the machine.  I have done a lot of google searching and have updated the bios and hotkey drivers that everyone recommends but this has not helped.  Anyone have any idea? I am still within my 30 day window and am seriously considering sending it back.

Hey hey, I have a new Ideapad U410 and I've discovered some problems involving the brightness settings and am looking for a solution. The brightness cannot be adjusted at all from windows 7. The slider that you have when you select "Adjust Brightness Settings" does not work. Also, in the power management options there is no change when switching between the various power management settings nor when switching between AC power and battery power. Finally, whenever I restart the computer the brightness is reset to the highest setting possible. This last issue is solved for some Thinkpads with a BIOS update but there is no bios update for the U410! (  I have called support and they have been unable to help with this situation. Luckily, the function keys on the keyboard still can adjust the brightness but I'm getting tired of adjusting the brightness manually every time I switch to battery! I hope that there is a solution out there! Thanks for the help, Jason

     I have Dell Inspiron13 7000 series laptop.Everything was working fine until 2 weeks back.
Suddenly I wasn't able to use F11/F12 keys to controll brightness.Even if I clicked I wasn't getting the actual brightness bar.I checked some blogs and youtube videos, which helped me and it fixed my issue.
Suddenly after almost a week or so, I am getting another issue.I can scroll up or down the brightness however it doesn't change any brightness level.Right now it is too bright but I can't change it.
Has anyone been facing this issue or resolved this?
Laptop was in perfectly operating condition before.I have been getting these issues recently after regular windows update.

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

After updating to W10 insider fast ring build 14393.10 on my Lenovo G580 notebook, the Fn+Up brightness control key combination has stopped working. To check if Fn+Down was working, I pressed them and the brightness went down to "0" and now the screen is always black both while plugged-in and unplugged. Hence, I'm not able to increase the brightness anymore.
FYI, the "Up" arrow button works normally but the combination "Fn+Up" doesn't work while "Fn+Down" does.
Safe Mode doesn't allow adjustment of brightness since it cannot load the display driver.
I tried installing a third-party brightness control software while in Safe Mode but then realized it won't work until I log in to my account, in normal mode, which I cannot do since the brightness is at zero.
Please help me asap!
PS:- I have managed to increase the brightness for now but still the combination isn't working. Fn+Left arrow key combination also not working for volume down while Fn+Right arrow for volume up is working.

Answer:Fn+Up brightness control not working after updating to W10 build 14393.10. Brightness is at zero.

you can change brightness settings from settings itself instead of using the keys - just to make things easier

Basically the title says it all, my computer is stuck on max brightness so the battery is suffering and using my laptop at night is now a pain. I already updated the display adapter and the option to change the brightness in my display settings is there but moving around the slider doesn't actually do anything.

Answer:My laptop (HP ENVY) isn't actually changing its brightness when I switch brightness.

Any changes that happened around the time this issue popped up? Like dropping the laptop or doing an upgrade or something?
