I have the exact same problem with the same monitor, both the HDMI and Displayport/USB C thunderbolt 3 adapter didn't work. I have a Dell XPS 15 9560, and called Dell support, who wanted me to return it.
Does anybody know a solution to this? I checked both the HDMI and Displayport cable work completely fine with other monitors? But the screen doesn't work with the other computer. Maybe it could be Intel HD graphics, which are on laptops/desktops hinders the connection? It is a G-sync monitor, 165 hz, 2560x1440 https://sarkariresult.onl/ , https://pnrstatus.vip/ & https://192168ll.onl/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1362326 Title: LCD panel sometimes says "No signal" and is blank, the driver thinks it is active To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/fglrx-installer-updates/+bug/1362326/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
