Thanks. Actually that edid-decode command merged your two monitors' EDIDs in a confusing way so I regenerated just the LG EDID from the original data. It shows no 2880x1620 mode so that must have been created in software.
Separately, it confirms 3840x2160x60Hz is supported by the monitor. But since the port on the laptop doesn't go that high then the availability of that mode will be intermittent and unreliable. ** Attachment added: "lg-edid2.txt" https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2162070/+attachment/5990484/+files/lg-edid2.txt ** Changed in: mutter (Ubuntu) Status: Incomplete => Triaged ** Changed in: mutter (Ubuntu) Importance: Low => Medium -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2162070 Title: Fake modes are not centered/scaled correctly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2162070/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
