Hi. Since installing AMD Radeon 17.7.2 and changing the pixel format to Full RGB, my pc continuously crashes when I attempt to watch a video - and I also experience slow response times also. As of right now, I have set the pixel format to YCbCr 4:4:4, as I am not experiencing any problems using this format. Is there a solution to this, and if not is YCbCr that much of a downgrade in terms of image quality? Thanks in advance .
