Hi.
I've recently sold my monitor and had hooked up my GPU to my old TV via HDMI. The picture was complete ass so I searched and was told to use GPU Scaling and VSR. I did. VSR worked fine but made no difference to picture quality. GPU Scaling completely stopped display altogether. I'm left with a black screen and no way to revert it, at least "known" way to revert it. I have zero display whatsoever.
AMD RADEON RX 5700XT
Driver: 20.4.2 (most stable so far for me)
