Brightness/gamma control doesn't work suddenly #253

Closed clidx closed 1 year ago

clidx commented 1 year ago

Version

2.4.5

Details

I rebooted and the gamma control doesn't work anymore. I got a warning saying I needed to launch the app as admin to get extended gamma range, clicked OK and nothing happened. I then opened the app with admin rights but it still doesn't work. There is no difference between 0 and 100% brightness anymore. I have disabled pause when fullscreen, but nothing. The application whitelist is also disabled. It's 22:12 here, sunset is set to 20:00 and sunrise is 07:00 (manual). Not sure why it's not working.

Steps to reproduce

Run program

Can you check the value of this registry entry?

HKLM\Software\Microsoft\Windows NT\CurrentVersion\ICM\GdiICMGammaRange

It should be 256.

It seems that registry tweak requires another reboot. Probably should have tried that.. but hey ho! Thanks.
