Ycbcr support for 1080p/4k bluray playback

FluidCashew6982 · Nov 8, 2017

I would like the support of Ycbcr chroma subsampling added to the colour space in the video settings of the xbox one X. Because of the use of the RGB limited there is a small change in colours (because all movies are encoded in the YcbCr 4:2:0 8 /10 bit
colour space depending whether they use HDR and rec 2020 colour space instead of rec 709 ) when converting from the YcbCr 4:2:0 to RGB limited colour space - polish portal hdtvpolska.com in their review of the xbox one X actually measured this inaccuracy of
converting colours. Also this would be appreciated when it comes to playback of ultra bluray discs with HDR and 4k HDR games and 4k HDR netflix&amazon playback as many devices (mostly projectors with limited 4k HDR support) can't work correctly with your device
as their bandwith is usually limited to 10 gbs HDMI (so it will only accept 3840x2160p YcbCr 10 bit 4:2:0 chroma subsampling) and won't work with your current 3840x2160p YcbCr 10 bit RGB limited colour space as it requires more bandwith. I hope this problem
will be resolved as an update to the xbox one X and to the ultra bluray player app.

UHD Blu Rays

It doesn't support 4K UHD playback.

If you are referring to "Mastered in 4K" discs those are just 1080p titles made from a 4K master.

New hardware is required to playback UHD Blu-Ray.

i noticed the same when watching 4k ultra blu ray hdr movies 24hz setting on. X box one x outputs only rgb and picture is a mess with my optoma uhd65 projector. You need to fix it output ycbcr on 24hz setting on too!!

If i unselect 24hz x box outputs 60hz ycbcr and picture is pretty good.

hi

I have this same problem on 4 separate Xbox one S consoles.

Try disabling 4K video output support from system settings. This returned all the consoles to being able to playback 3D bluray but only with 1080p set as video output. Once 4K is turned back on the 3D stops.

Hope this helps

The HDMI IN on the XBOX ONE / ONE S / ONE X are all just 1080P there is no 4K pass through on those consoles.

The Xbox One S Supports 4K Bluray and 4K screen resolution - not 4K gaming

The Xbox One X Supports 4K Gaming, 4K Bluray and 4K screen resolution

- Game developer has to make the game 4K

- 4K pass-through is a hardware feature that does not exist within the console. You'd be better

off running your 4k Sky Q into the TV directly. (the xbox is doing what it's designed to do)

@cheesyhunter1

Isn't your Spiderman movie just mastered from a 4K source and still only output at 1080p ?

Those blurays aren't 4K

I have a collection of 4K demos, but the console's media player doesn't support them.

Looking forward to true 4K output on the console

House of cards on Netflix is great as is Breaking Bad in 4K. :eek:
