I've never used resolutions that high under Linux, but...

... I'm not convinced these issues are related directly to a problem setting the resolution at the "xrandr level".
It sounds more as if something in the plasma stuff doesn't have the correct idea of the resolution it should be working at.

Maybe, maybe not. It can't hurt if the resolution is already set properly (or if it's at least in the list of known resolutions) when the KDE environment starts up.

There's also a plasma ML which may be a better place to ask for assistance if this continues to be a problem.
