✭✭something else?I'm still rocking an original xb1 so for me the 4k tv upscales the 1080p. Looks pretty good though."It is a lovely language, but it takes a very long time saying anything in it, because we do not say anything in it, unless it is worth taking a long time to say, and to listen to." - Treebeard3 -

and older article but the info about pixel formats is still relevant
YUV is analog version of YCbCr which is digital. uses less bandwith than RGB pixel format.Edited by Lady_Linux on November 21, 2019 6:50AMI simply must protest. There are no Penguin avatars for me to use in the forums.

Lady_Linux✭✭✭✭✭YCbCr 4:2:2honestly i run ycbcr 422 in windows but rgb 444 in linux. amdgpu doesnt seem to have the option to switch pixel format. and someone suggested that since my card does rgb and my tv does rgb both natively that switching to ycbcr422 would require each to translate the signals.. which is something i hadnt realized
from another forum
"No, afaik the graphics card native output is RGB anyways.
So actually it would need to convert it to YCbCr, send it over the cable and then the TV converts it back to RGB before displaying it.
in terms of bandwidth needed:
RGB vs YCbCr 4:4:4 = same data rate
vs YCbCr 4:2:2 = 2/3 of the RGB data rate
vs YCbCr 4:2:0 = 1/2 of the RGB data rate
Since your GPU / TV seem to be HDMI 2.0 compliant there is enough bandwidth for 4K 60Hz with RGB."
My thought was that if you changed the pixel format you could lower the bandwidth and reduce the load on the gpu and thereby increase performanceEdited by Lady_Linux on November 21, 2019 7:29PMI simply must protest. There are no Penguin avatars for me to use in the forums.

spekdah✭✭✭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.

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
Easy to work with as a developer while using less bandwidth yet retaining the full visual quality.

that's windws only. not linux article. i have no issue with either really i have 4k60 in both but amdgpu driver for linux i cant find documentation to compel it to use ycbcr422 on linux.I simply must protest. There are no Penguin avatars for me to use in the forums.

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.

Hmm, this is the result I get when using YCbCr 4:2:2: https://imgur.com/a/7lUUKmj (RGB left, YCbCr right).
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.1 -

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 ...

Strange indeed... I couldn't really find any information on this on google either, except this article from a guy that experienced the same fringing behavior. So I'll just blame it on my monitor too, which probably supports YCbCr mostly for compatibility, but is happier with a RGB signal.0 -

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
