I bought RX 560 and have this issue. On 4k@60Hz always got 4:2:0 when I fresh start computer.
Then I need unplug HDMI put it to another 1 and then I got full RGB 4:4:4 (!!!)
Even when I restart computer, this pixel format still be enabled.
It's so annoying!!!
As I checked you can't mange this problem (wrong proper pixel format) for almost 2 YEARS now!!!! What's wrong with you guys?!
You just push you fans into nVidia arms... I always bought yours cards like FOREVER!!
Also GREAT JOB with cutting units in RX 560.. MASTERMIND of bad marketing!!!
I bought new card, that is worse than was sold before....
I will buy nVidia card and check if this will also occur, if not.... AMD customer -1
