Hi. So I'm not entirely sure what I did but I was using AMD Catalyst control center and I clicked on something and my monitor began displaying "Input not supported". I restarted my computer and once windows loaded up it began displaying it again. Ive been trying for some time now to find a solution. I found that safe mode does in fact work. If I go into safe mode I can delete my video drivers and restart my computer. At that point my computer will start normally and run normally for the most part(It seems I can't play games in this state). It will automatically reinstall my video drivers. Once the drivers are reinstalled and the computer restarts the problem begins again.
