So although everything is working fine in windows and ubuntu 19.10; i swapped my onkyo receiver for a newer Denon hdmi 2.0 receiver - the AVR-X1400H; same issue. i connected to pc directly to the screen; same issue i switched to a different brand of premium hdmi 2.0 cable; same issue.
i've also installed the ubuntu budgie flavor beta; same issue. I think it's pretty safe to say, this not a local hardware issue at this point. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1870637 Title: 20.04beta: Cannot set 3840x2160 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1870637/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
