Hello, I have XFX Radeon RX 5600XT Thicc III and I can't change gamma settings in any software like quickgamma, Calibrize or DisplayCAL (I need the right gamma to work). F.lux won't work also, it's really annoying. I was trying 3 or 4 different driver versions (20.4.2, 20.4.2, 20.10.1) and still nothing. Additionaly in games slider of brightness/gamma is not working. My operating system is Windows 7 x64. My spec: ASRock AB350M-HDV R3.0 (with newest bios), Ryzen 5 2600, 2x8GB Patriot Viper 3200MHz. Does anywone knows solution?
