https://bugs.freedesktop.org/show_bug.cgi?id=107607 --- Comment #5 from Jerry Zuo --- Thank you. You connect both HDMI and DP to UP3214 with DP1.2 enabled, switch back and forth, and the warning is showing up. When the warning is observed, a delay is also observed. Am I right? -- 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

The monitor has several inputs. Over the OSD (on-screen display) you can tell the monitor what input signal it should display (or the monitor auto-senses it itself). Hopefully, that makes sense. -- 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
