I have an older 4K TV and it only supports 4K@60Hz at 4:2:0.
I bought a CAC-1070 mainly because I read online that it supports 4:4:4 to 4:2:0 downconversion but it dosen’t seem to be working, how do I activate it? (Can only select 30Hz on anything above 1080P on an older NVidia card)
I had a look inside and found it uses the PS176 chip which ive read is supposed to support this function.
Is it the NVidia driver being overly clever? or is this function not active in your adapter?
