How do I do that? Do you have a link I could go to and learn how to

I have a KVM and whenever I switch from Fedora to the other PCs, I start
getting a bunch of lines on the journal complaining that the system could
not get the EDID info:
Search for EDID in the kernel command line parameters doc:
https://www.kernel.org/doc/html/v4.14/admin-guide/kernel-parameters.html
That tells you where to put the edid blob and how to point to it
on the kernel command line. If you boot when the monitor is correctly
connected, there should be a file like this:
/sys/class/drm/card0-HDMI-A-1/edid
That is the edid it read from the monitor which you can copy
and point at on the command line. That card* directory is
different depending on where the monitor is connected.
There is also a read-edid tool that can dig up the same info.
