Thanks. If the OSD doesn't show decimal places in "60Hz" then it doesn't prove anything.
Since this seems to be fundamentally a signal synchronization problem I can only recommend installing an official Nvidia graphics driver. According the the Nvidia website, your GeForce GTX 1660 SUPER should be supported by all our current drivers so please open the 'Additional Drivers' app and use it to install one. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2074559 Title: [nouveau][Samsung SyncMaster] Top margin of secondary monitor covered with black flickering rectangle To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2074559/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
