I am using an old gm2200 its my brothers old monitor but it had dvi and because my old monitor had vga I changed to it and in games the signal is good but the pixels change to weird colors.Its not probably my gpu because on my previous monitor I didnt had any problem.My specs r9 280,i5 6600k,ssd 250gb,2tb hd max gpu temps 75 and cpu 50.Screenshots
