When I launched GOG Galaxy to download The Witcher 3 my main monitor went from 120 Hz to 60 Hz and my 3rd monitor stopped getting signal and no longer works even with different cable. I don’t know what does the Witcher 3 installer sets that disabled 3 monitor setup or change desktop resolution.
My 3 monitor setup is borked now thanks to running this installer. Any clues appreciated, Please help
