    Nope.

    That did not solve the problem...

    Kodiak,

    Well, with "Adaptive Brightness" and "Dim Display" turned off, it's shouldn't be dimming automatically anymore.

    You might check to see if Asus may have any included software installed that may also be controlling the dim and brightness of the display.

    Hi.

    I know this would be difficult to understand because my OS is in Portuguese but I'm now testing these settings:



    I don't have any asus software installed

    Will see how this goes and then will post back the results.

    Thanks for your help

    You didn't set "Dim Display" (obscurecer ecra apos) to "Never". Instead you have it set to do so after 100 minutes.

    Hi Brink

    This is what I'm testing now.

    I've done Dim Display to Never already and that did not solve.

    As a test, change all of the brightness settings to 100%, and dim settings to 0% to see if that may help if something else may be dimming the display. This way it will still be at full brightness if it uses these settings to dim by.

    Sorry but I don't like to work with the brightness so high. It "hurts" my eyes

    You could set it to what you like instead for it to still work. The main thing is to have them all set to how you like so that it wouldn't matter if the dim or brightness changes since it would only change to what you have the % set to.

    Windows 8


    Hey all,

    I am new to Windows 8 64bit. I am primarily a gamer and I have built my system for this specifically. I have been investigating this issue for about a week now almost every post that I see about this is related to a laptop.

    I am running a desktop (always plugged in) computer. Windows 8 seems to be geared more towards the mobile experience and has really put me in a place where I feel like I have made a mistake in transitioning to Windows 8 and Microsoft is unwilling to help without an additional financial investment.

    My issue: Adaptive Brightness will not turn off. I have disabled this in all the power profiles and even created a custom power profile with it disabled. This desktop doesnt have any "light sensors" but I went in and disabled the Sensor Monitoring Service as well.

    The adaptive brightness "feature" continues to dim and brighten my display based on the "brightness" of the image that I am viewing. For example, when I am playing Call of Duty: Black Ops 2: Zombies, you can imagine that it is a very dark game to begin with. Well, Windows 8 wants to dim the monitor anytime the in game lighting gets low. I move into a dark area, you can see everything dim, text, hud, OSD. As soon as the image onscreen brightens, you can see the whole monitor increase power usage.

    This happens in Guild Wars 2, World of Tanks, Neverwinter, COD, browsers/websites (including this one), picture viewers, absolutely everything. The darker images cause the entire monitor to decrease its brightness. I have tried re-enabling this feature and then disabling it again. It just doesnt want to turn off.

    I have updated drivers, modified video settings, changed video cards, nothing seems to stop it. I have loaded Windows 7 as an alternate OS for dual boot, this doesnt happen in Windows 7 but I only have a 32bit Windows 7. The only thing I havent tried is wiping the drive and starting over but I am certainly hesitant to do so.

    ASUS Sabertooth L77
    Intel Core i7 3.4ghz Quad Core
    16gb DDR3
    2x 128gb OCZ SATA3 SSDs.
    ASUS Radeon 5830 Dark Knight

    I am hoping for someone to come save me from going insane from Win8 which I really like and which runs like an absolute dream on my computer, except for this one, very annoying thing.

    Hello Kirk, and welcome to Eight Forums.

    This doesn't sound like the "Adaptive Brightness" feature is doing this to me. Especially since you turned it off and disabled it's service.

    See if doing a clean startup to troubleshoot may help ID what may be causing this.

    How to perform a clean boot to troubleshoot a problem in Windows Vista, Windows 7, or Windows 8

    Hope this helps for now,
