I changed my resolution from AMD Catalyst Control Center to somewhere 1990 x something. which i forgot and then i get colors on my screen and i can't do anything. there is rainbow lined colors. then i restarted the pc trying to get into safe mode which I did but im stupid enough to change it to 1990 resolution again which Removed up again.... and my monitor is showing "input not supported" why is this happening to me. i can't do anything.. ireally need help here.

i have a amd radeon sapphire 6950 series and intel i5 2300k......

my monitor highest resolution is only 1440.... idk why i did that..

Thnks
