Anything I can help with ?? more debug logs anything ??

It's really annoying having a large 4k monitor and have only 30Hz refresh rate.

I believe this is a tiled display. Correct me if I'm wrong. This means that
besides MST support (where we still have to iron out some bugs) this display
also requires tiled display support which we currently don't have.

I have no idea what a tiled display is.

If I use the Intel display port I get or more correctly used to get two
displays that I could then combine with xrandr into one larger. Now the kernel
driver presents just the combined one directly no need to manually do anything.

I believe it means, that there are actually two panels.

I have the same monitor. 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.
