Under Gnome, when the vm window is maximised to 3840x2160 (4K) the maximum available space
that Gnome can be scaled to without getting horizontal or vertical bars is 3840x2075, but
under KDE, for the same vm window size, the maximum resolution KDE can be scaled to is
3840x2069. The question now is why is there this sizing difference between Gnome and KDE?

resolutions (these were not required with Gnome).
> The other issue I encountered was that Fedora is not setting up valid video
resolutions for the monitor I have. Part of this could be that Fedora has no idea what the
monitor is because it doesn't have specific support for it, the other part is it is
making invalid assumptions about the monitor capabilities. A lot of the resolutions Fedora
is setting up are 16:10 resolutions, which for my monitor which is 16:9 are not valid.
The monitor is responsible for reporting it’s mode information to the operating system
using EDID packages. I don’t recall that kernel having any quirks for monitors, but it has
been a while since I worked closely with EDID.
If the mode lines are wrong then the monitor is first thing to suspect.
Look in dmesg for errors include edid in the line.
Under x11 you can use xrandr —verbose to get the EDID information.
There is tool ediddecode (?) that will decode the hex dump you get.
Thanks Barry,
I'll check that out. I am using a 4K monitor that has HDR
capabilities which, like windows, I won't get that functionality in
linux without a monitor specific driver, which doesn't exist for linux.
I'm not sure whether the issue I'm seeing is Fedora or the vmware video
driver, but I also get the same issues if I use Virtualbox instead of
Vmware Player. Before I put the xorg modelines in place xrandr would not
list the 4K resolution as being a resolution that was achievable.
