Xorg Scaling Issues

[Stephen Morris]

Hi,
     I have config file in /etc/X11/xorg.conf.d that is listing 
modelines for all resolutions that xrandr indicates is supported by the 
vmware video driver. With that file existing can anyone suggest why 
Gnome in Xorg will scale to 4k resolution when the desktop is scaled, 
but Plasma in X11 will not scale?

regards,
Steve
