My laptop is an ASUS with two GPUs:

  • (Integrated) Intel hd graphics 520. I think this manages the monitor.
  • (Discrete) Nvidia geforce 940M. For games. Both have the latest drivers.

What happens is when I start a game, the screen dims and I am unable to increase the brightness. Some notes:

  • The backlight keyboard also acts up. Turns itself on.
  • It only occurs in fullscreen mode.
  • I have "adaptive brightness" turned off in display settings (I have no adaptive brightness option in power options).
  • Some people on other threads mention the "Intel Power Saving technology". I have no such setting in my Intel control panel.

Everything is absolutely fine outside programs. But only when I start games in fullscreen, this happens. It's quite annoying.

I think my issue is the same as this: Can't disable auto screen dimming on ASUS laptop Windows 10 However I do not see an option to turn off power saving tech in my control panel (Intel command center).

You need to disable both Panel Self Refresh (PSR) and Display Power Saving Technology in the Intel Graphics control center, then reboot and retest.

Some vendors don't implement these advanced features correctly, resulting in similar bugs.

I am struggling with the same. I found out that a part of the problem is the ATK package. If you go to process and disable Hcontrol.exe then your games wont act up.

Are you able to find a solution, knowing the ATK package is part of the cause? I havn't found a real solution yet.
