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: liammurphy@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.
