https://bugs.freedesktop.org/show_bug.cgi?id=101026 --- Comment #2 from dwagner--- I just wanted to mention here that I currently use an RX 460 GPU to drive an HDMI display at 3840x2160 60Hz, this became possible some time ago when DC code was merged into the open source amdgpu driver. (BTW: HDMI audio also works for me.) I use a kernel compiled from https://cgit.freedesktop.org/~agd5f/linux/log/?h=amd-staging-drm-next as of "commit 94097b0f7f1bfa54b3b1f8b0d74bbd271a0564e4". So I think this bug-report could be closed with "works with bleeding edge amdgpu version, now". -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugs.freedesktop.org/show_bug.cgi?id=101026 --- Comment #1 from Harry Wentland--- Hi Liam, I haven't tried it myself but I don't think this will work with the upstream amdgpu driver. You can try Alex's amd-staging-4.9 or amd-staging-4.11 trees and enable CONFIG_DRM_AMD_DC to get support for our new display driver which is not upstream yet. That should give you support for 4k60 over HDMI. I don't think Mesa has anything to do with this.

https://bugs.freedesktop.org/show_bug.cgi?id=101026 Bug ID: 101026 Summary: RX 550 HDMI 4k 60fps not working, DisplayPort is. Product: Mesa Version: git Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component: Drivers/Gallium/radeonsi Assignee: dri-devel@lists.freedesktop.org Reporter: liammur...@fastmail.com QA Contact: dri-devel@lists.freedesktop.org Hello everyone, Please let me know what logs/command outputs I can give, not sure what would help you all out. I recently bought an AMD RX 550, first GPU with the Polaris architecture (so I assume growing pains here), and am experiencing a bug where HDMI at 4k 60 fps is not working, but DisplayPort does. HDMI 4k60fps is working for me under Windows, so to me it's safe to say this is a Mesa problem. This was happening on Mesa 17.0.5 and 17.2 git on OpenSUSE Tumbleweed, in addition to Mesa 17 on Ubuntu 17.04. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
