RX560 Pixel Format Changing - 17.12.2

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

Re: Pixel format issue...

So what's the problem? Full RGB is superior to 4:2:0.

Re: Pixel format issue...

Yea.. but I got 4:2:0 in 'standard'. Just need to switch HDMI with computer on, to another one. Then I get full RGB 4:4:4

Also after 'sleep' mode back from 4:4:4 (after HDMI switch) to 4:2:0.

So main problem is, that I got 4:2:0 instead 4:4:4 (this mode don't even display in option). Before I switch HDMI port on 'live'.
