Tried another test. In the monitor settings menu under Display there is a option called "DP 1.2", by default it is set to Enabled. If I set it to Disabled I get the PIP behaviour - Ubuntu detects the correct native resolution and the image appears.
If I set it back to Enabled the bug comes back. Is their a bug in the DisplayPort 1.2 implementation that doesn't affect earlier revision modes? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1494095 Title: Dell U3414W screen not turning on in 3440 x 1440 mode To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1494095/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
