Along with looking at
https://www.kernel.org/doc/Documentation/EDID/
as pointed to by Tom, you should also look at

Basically, because you have a KVM that doesn't relay the EDID data from the monitor
to the kernel faithfully you'll need to override it. The link above gives
information on how to do that. The hard part can be getting the actual EDID
information from your monitor to place in /usr/lib/firmware/edid . I only have
experience doing that with nVidia binary drivers where it is easy to do with their
nvidia-settings utility. There is a monitor-edid package available which supplies
monitor-get-edid which may or may not work. If you install it, you'll probably find
it gets a selinux error which you can fix easily. But it won't work for me after
that but that may be due to my choice of drivers.
Anyway, something like this happened to me quite some time ago. I found the least
painful thing to do was to research and then go out and buy a good KVM. I no longer
have the need for KVM so I can't recommend a product. But that is what I would do.
Not only would it solve the problem for me with the least amount of pain/effort I
wouldn't have to go through the same process in the event of a fresh install or
another reason.
