--- Comment #17 from Andy Pillip <andy at madspunky.net> --- This is not a cable issue. I just figured out that for me the issue only occurs on a dual screen setup. Now I'm running the 3840 resolution on my external screen while switching off the internal one â without any issues. Tvrtko, do you have a dual or single setup? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
