Hi Christopher. Answering your questions in turn:
1) All I can say for the moment is that it was OK in Ubuntu 17.10 and not OK in 18.04. 2) The monitor is actually a Samsung television, model no. UE40EH5000. However, I want to be clear that the issue is with the screen in the laptop itself, not anything external. The issue occurs whether or not an external monitor (television) is connected. 3) Straight HDMI cable. To be clear, the behavior as I see it is exactly as bug 1300349. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777257 Title: Dell Inspiron 17r 5737 Ubuntu 18.04 Video Looks Very Strange To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1777257/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
