hello, i recently bought radeon r7 250. It works fine until i installed radeon software. When i installed it, i can't set higher resolution than 1920x1080 (i need 1920x1200 which is my monitor native resolution) and my screen is dark and pixelated. I checked drivers, i have latest one. I try reinstalling software, Changing cables, changing ports on card and monitor, and it still don't works. Sorry for my bad english, i hope you will undersand.
