My setup is the following:Last I checked, NVIDIA only supports 4:2:0 with 3840x2160 @ 50/60 Hz and higher, and GPU scaling won't work with 4:2:0, so what you want can't be done. Are you not able to get 3840x2160 @ 60 Hz with 4:2:2? That's only 12 Gbps. YCbCr is supposed to be always limited range. What happens if you try lower resolutions with RGB instead of YCbCr? The first detailed resolution is what GPU scaling will scale to, so try making that 1920x1080 @ 60 Hz to avoid the black screen. The best solution might be to get an HDMI signal booster and two 5m cables. Thanks for the tips. Yeah, I can't use 422, the bandwidth limits me. And the whole mess with resolutions and 420 now makes sense (except for the TV, which shows 420 limited as full, but 1080@422 as limited - probably some stuff in the TV firmware itself). I've ordered what you advised - repeater and 2 nice 5m cables. Thanks again! |
