You certainly seem to have the latest and greatest Intel GPU which should support 4K up to 120Hz:

If you can then please try to get a Thunderbolt-to-DisplayPort CABLE. The Thunderbolt end looks like USB-C but it's much more capable and can carry a full-speed DisplayPort signal. This is probably not a software bug, or if it is then probably not one we need to worry about if you just get a different cable. In the meantime you might want to try selecting 'Ubuntu on Wayland' from the login screen to see if the experience is any different there. ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Changed in: xorg-server (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1886729 Title: Dell displayport YJ3Y6 adapter doesn't drive 4K screen properly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1886729/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
