https://bugs.freedesktop.org/show_bug.cgi?id=107731 --- Comment #11 from L.S.S. --- So is there a possible workaround for monitors/KVMs that could cause this issue? Sadly for 4-port DisplayPort KVMs with working 4K@60 there are very few alternatives... most are either only DP 1.1 or only 4K@30. Although I have to admit that this KVM (ATEN CS1924) is notoriously picky when it comes to cables... only stock cables or some highly expensive DP1.4 cables could make 4K@60 output work stable, but stock cables are only about 2m and in reality I needed a few 3m cables (which cost me a handful to get the right cables for the job) as some of the PCs are placed a bit far away from the KVM. -- You are receiving this mail because: You are the assignee for the bug.
