Mine does.
I've done a lot of DSP work and 4:2:2 is by all accounts the better format.Lady_Linux wrote: »... YCbCr ... uses less bandwith than RGB pixel format
You can read about it here about an article trying to fix HDMI colour issues;
Has colour charts for the various formats and informations on the signals for both Nvida and AMD cards.

Hmm, i can't say i share that experience.
One of the projects i worked on that involved 4:2:2 was to inject text into a video stream (think along the lines of closed captioning) and there were no visual artifacts around the text to background borders.

Since this "color cast/fringing/aberration" does not occur when using YCbCr 4:4:4, I assume it has something to do with the chroma subsampling that's happening with YCbCr 4:2:2, but maybe other monitors do a better job at converting sub-sampled YCbCr back to RGB than mine.

HOW? Would you please tell me sometime. It's easy in windows but in linux i havent found the answer. Was forced to got to amd on reddit in search of a clue. Still waiting for a reply on reddit.
Lemmy see if i can dig up some old screenshots from our App ...


The above are screen captures from an App that runs on a proprietary hardware box that is in-between a set top box and a TV.
It gets its source signal from a set top box, adds additional text (info about real time logo detection in the stream) and then passes the altered signal to the TV. Everything is done in 4:2:2 ...

How do I know? Refer to stadia for ESO yes or no. Plz no one who actually is legit names themselves with Linux. Even with 6 figure pre bonus salary at Amazon people run windows. So *** what if your resolution is different. 4K *** is overrated.
4k past 60fps is impressive but this console junk they pass as 4k is laughable... I play eso in 4k over 100fps in some areas and its impressive to say the least, specially with post processing effects software
