Since your system has hybrid graphics (both Intel and Nvidia GPUs) it's unclear which monitor connectors are connected to which GPU. The answer varies between laptop models...
If we assume the answer is that your HDMI port is connected to the Intel GPU (which would be pretty normal) then this is a duplicate of bug 1606103. If your HDMI is connected directly to the Nvidia GPU then that's an Nvidia bug. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1638565 Title: HP Envy 34c resolution maxes out at 1920x1200 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1638565/+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
