I think it is going to be "difficult" to track down the actual culprit.  I say 
that because of my following experience.

1.  qemu VM, Gnome on Xorg, gdm display manager.  Display changes size 
depending on the qemu console window size.

2.  qemu VM, Plasma on Xorg, sddm display manager.  Display does not change as 
the qemu console is resized.
     I need to add modelines to get what I want and select it in 
System-Settings.

3.  qemu VM, Plasma on Xorg, gdm display manager.  Display changes size 
depending on the qemu console window size.

4.  VirtualBox VM, both Gnome on Xorg with gdm and Plasma on Xorg with sddm the 
Display changes size depending on the
      VirutalBox console window size.

When it comes to the qemu cases I thought it may have been due to the video 
driver.  But in all cases lsmod shows the
same set of virtio modules loaded.

Also, in VirtualBox the modules are all vmwgfx.

I suspect it may be somehow related to kwin_x11 and how it is integrated.

How did you you get the monitor-get-edid to work, when I switch to root with "sudo 
su -" and issue the command I get access denied, have I done something wrong?

I don't think you've done anything wrong.  I think it has to do with the 
drivers in use.  As I mentioned in another post, I can get
the correct output with nouveau but not with nVidia.  Also having to do with 
accessing /dev/mem.  It also works fine in a qemu/virtio
environment.  I forgot to check with VirtualBox.  I don't have VMware in order 
to test that.
