unable to obtain 2160p 4:4:4 or 4:4:2 full rgb at any refresh rate, in fact i'm stuck at 2160p 4:2:0 60hz.
If I drop to 1080p all options return. Now before anyone starts asking what my signal path looks like or whether I have all the right cables and settings on my PC, TV and receiever... If I put my RX580 back in I can happily achive all expected option ,e.g 2160p full RGB 8bit for deskop but also 4:4:2 and also 2160p full RGB 4:4:4 10 bit at 30 hz as I should be able to.
If this yet another fault with this god awful card?
I only noticed this today as I notrmally just use 1080p for reasons I wont bore you with but if my PC cant achive anything but this now this is really bad.
turns out this card desnt llike display port to HDMI converters, when I plugged my TV straight into the HDMI all optins came back so this is another driver bug i suspect, i'll change the title
