Description of problem:

dear Mesa gang, dear AMD gang

I have a Panasonic 4k 55" which is wrongly detected as 58" and detected/default resolution is set to 4096x2160 (this remind me another bug I reported ~3years ago, precisely about wrongly detected/calculated size/resolution, back then it was just FHD)

AMD A10 PRO-7800B R7, 12 Compute Cores 4C+8G   
ASRock FM2A88X-ITX+

What is urgent here is the an attempt to change the resolution to correct one (whether Wayland or X11) kills everything(black screen), cold power cycle is what's left.

please let me know if I can get you any more info.
