[SOLVED] Monitor is darker than before

[flightn]

I was playing a game and my PC froze, restarted it and now my main monitor and darker than my other 2, less colorful and everything

checked my nvidia control panel and all the settings are the same and i checked the brightness on the monitor and its all the way up

also now whenever i tab out of a game my screen goes back for 5+ seconds.

could be a damaged graphics processor, a corrupt driver, a bad\damaged cable, a bad output from the GPU, a bad input on the display.

you will have to do some troubleshooting like trying different arrangements of the displays and cables.
also try removing graphics drivers & settings with DDU and reinstalling the latest available package.
