    Laptop monitor auto-dimming when starting games (can't be turned up).


    Hello everyone,

    I created this account, as I have looked for answers for this infuriating issue for days, without being able to solve it.

    I have an ASUS Zenbook UX303UB, with an integrated graphic card (Intel HD graphics 520) and discrete card (Nvidia geforce 940m). This problem is well documented all over the web but yet no real solution has been found.

    The problem is that, when I start a game, the brightness automatically dims to very low levels. I have tried to go through every possible setting but to no avail. I noted that the problem occurs only when I start games. Otherwise the brightness functions totally normally and fine, and doesn't "adjust". I thus suspect that entering the game triggers a "power saving" function that lowers the brightness (it also for some reason turns up my backlit keyboard, weird!).

    Here is what I tried:

    - Disabling adaptive brightness: There is no option to do so under the "advanced power options", but in the windows 10 display settings, I turned it off ("change brightness automatically when lightning changes). No change.

    - Some people say that the problem is the Intel integrated card, which "manages" the monitor. Specifically the "intel power saving technology" which needs to be disabled. I tried the "turn it off through the registry" option as I do not have an "intel power saving technology" option in my Intel control panel. That did nothing either.

    - In power options, and in the intel graphics control panel, I turned the power setting to "maximum performance". Changes nothing.

    - Updated drivers of Nvidia and Intel card. No change.

    I am at a loss. However I found ONE FIX which is problematic. Disabling the "generic PnP monitor" under device Manager fixes the issue! The monitor no longer adjusts brightness when entering a game or at all! However the problem with this fix, which will be obvious to all, is that this disables all brightness controls on the PC! I no longer have a brightness slider in the taskbar, nor do the function shortcuts work. Disabling the Generic PnP Monitor disables everything! Here is where I found the fix: Screen brightness dims when starting game | Tom's Hardware Forum

    I have a feeling, that the problem is some kind of power saving setting in the computer. And specifically with the Intel Card as apparently in laptops, it "manages" the monitor.

    :)

    Window 10 brightness/dimming cant turn off

    i have been looking for a fix for this for a few days and everyone else that ask has been asking for laptop and non for desktop. i want to disable to the auto brightness/dimming on windows 10. it is extremely annoying when i'm playing a game and it comes
    to the dark part the whole screen start to dim which makes it harder to see. i tried going to system and changing it in the power advance setting where i found dimming been removed but instead brightness has been place there. i tried disabling it and it didn't
    stop the auto dimming. does any one have any ideals? i was able to disable it in windows 8 but since i upgrade i cant turn it off.

  3. Upgraded to Windows 10 now Samsung laptop is dimmed; upgraded all drivers for monitor, display and other devices

    The error I get is LCDModeChecker fail intel: CLSIDFromProgID. I have updated all the drivers for the monitor, display and other devices, as well as adjusted auto dim. I have contacted Samsung support, they had me download there most automatic updates,
    but the files were blocked because of windows, and suggested that I contact microsoft support.

    Has anyone had this issue with their Samsung laptops? I have a Samsung ativ book 9; was running windows 8.1 without any problems, until a few hours when I upgraded to window10 and got the dimming issue (screen is so dimmed can barely see anything ) and
    the error above.

    How do I fix this?

    If you are using a desktop, follow the steps below.

    • Navigate to Start>Settings>System>Display.
    • In the right pane, click on Advanced Display Settings.
    • Click on Color Calibration under Related Settings.
    • Provide password (if any) for the UAC prompt and click on OK.
    • Click on next and follow the on screen prompts to adjust the brightness and contrast.

    If the issue still persists, suggest you to change the display settings of the monitor using the option keys provided in the monitor.

    Hope the information is helpful. Keep us posted on the status.
