Hi, On the videocard a premium hdmi2.0 is plugged in which connects to my hdmi2.0 Onkyo TX-NR646 amp, which acts as a switch for my windows pc and my ubuntu pc's.
The Onkyo hdmi2.0 out is connected to my Philips 49inch 4K TV. I will try to connect ubuntu 20.04 to my tv directly and report back here this evening. This however is no solution for me since i have 1 4K screen and two pc's and want my amp to act as the switch for both pc's -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in 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 _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
