Bug ID: 106999 Summary: [raven] 2160p@60Hz no longer available Product: DRI Version: DRI git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: mike@fireburn.co.uk
I'm not sure what's changed, if this is an X, DDX or Kernel issue but the number of modes has decreased on my 2400G and 60Hz is no longer available

--- Comment #9 from Mike Lothian mike@fireburn.co.uk --- I have a feeling that Kwin was trying to modeset back to 60Hz which was causing Xorg to crash and the error to appear in the dmesg
I'll post the Xorg.0.logs if I manage to reproduce the issue

--- Comment #10 from Michel Dänzer michel@daenzer.net --- Is this different from bug 106959?
https://bugs.freedesktop.org/show_bug.cgi?id=106999
--- Comment #11 from Mike Lothian mike@fireburn.co.uk --- It might be the same, the EDID says the TV is capable of both 10bit and 12bit colour, I was under the impression that HDMI 2 was able to do 2160p@60Hz at those colour depths
https://bugs.freedesktop.org/show_bug.cgi?id=106999
--- Comment #12 from Alex Deucher alexdeucher@gmail.com ---
From what I can see the HDMI 2.0 spec only supports 4k@60 at 8 bpc. I think
you need HDMI 2.1 for 4k@60 with 10 bpc or greater.

--- Comment #13 from Mike Lothian mike@fireburn.co.uk --- What is Raven capable of? I know my SkyQ box outputs at 2160@60Hz in 10bit colour

--- Comment #14 from Ilia Mirkin imirkin@alum.mit.edu --- (In reply to Mike Lothian from comment #13)
I know my SkyQ box outputs at 2160@60Hz in 10bit colour
https://en.wikipedia.org/wiki/HDMI#Refresh_frequency_limits_for_HDR10_video
4k@60@10bpc needs YUV 4:2:2 for HDMI 2.0, so it can't handle RGB (or YUV 4:4:4). That's probably the discrepancy - there's currently no great way for userspace to select which encoding variant is to be used (or what bpc to send it at).
