thank you very much has all

I'm running into the same issue. Will the next version of XbmcBuntu be updated to support these resolutions?

yes, it is necessary to wait has a correct price
the hardware graphite 4K
has 60 Hz

For now you guys will need to include those modelines yourself in the xorg.conf by following Configuring resolution via xorg.conf (wiki) for how to do this and adapting that to the 4K modelines/validation
After searching some-more I found https://devtalk.nvidia.com/default/topic...-screens-/ and https://devtalk.nvidia.com/default/topic...tx-650-ti/
That's 3 modes right there with the validation changes required to get them to work.
Haven't found any info on 60Hz modes for 4k yet and I wont be looking anymore as I dont have a 4k tv to test I also suspect not many developers do either. So you guys need to test this anyway.

Don't forget that there are Kepler nVidia cards, at least under Windows, that will output the HDMI 2.0 3840x2160/60p 4:2:0 resolution over HDMI 1.4 (as the bandwidth of HDMI 1.4 can carry 4:2:0 2160/60p content)
No idea if the Linux driver support is there as well. This is only really useful for video content as the chroma is subsampled to 1920x1080 so 4:4:4 content will have reduced quality, but almost all video is 4:2:0 by the time it gets to us consumers...

Supposedly FULL HEVC decode and HDMI 2.0 arrives with the Geforce 960 in a few weeks time. No idea if Linux support will be made available on release day.

Looks like livdpau now has HEVC V1.0 support. I guess a Geforce 9XX driver and FFMPEG driver is still a ways off. Have access to this Sat test stream but it looks rather bleeding edge, VLC 3.0 reports this:
Codec: MPEG-H Part2/HEVC (H.265) (hevc)
Res: 3840x2160
Decoded Format: Planar 4:2:0 YUV 10-bit LE
How far off do you think support for this type of stream is?
