With Linux 4.17 and 4.18 at least GDM 3.28 and 3.30 are correctly displayed over the full screen. Could you please retest? PS: The monitor, unfortunately, only gives problems with the free drivers (Intel and AMDGPU) and firmware (UEFI of MSI B350M MORTAR (MS-7A37)). I believe it’s the monitor firmware, but my colleagues say, they do *not* have any problems with the proprietary Nvidia drivers and Microsoft Windows. So, it’s either a bug in the free drivers, or the proprietary drivers work around it somehow. Here are my bug reports for that. I do not know if these are specific drivers bugs or in the generic DRM code. [1]: https://bugs.freedesktop.org/show_bug.cgi?id=107607 [2]: https://bugs.freedesktop.org/show_bug.cgi?id=107845
