HI
Yes I have same experience.
I beleive its because the DDC/ EDID info sent from screen over
the connection cable
is lost if the KVM and screen is not connected to the computer
at start up.
If I make sure that the screen is attached to the computer when
the computer powers up
a Usable resoultion/timing is selected by the graphics card.
I don't think that this is limited to DP either.
I use a ugreen 4port HDMI KVM for Mac mini/workstation/old workstation/R
Pi. Sometimes if I boot a device and forget to switch the KVM to the
correct port then I get a black screen and have to ssh to whatever to
reboot it.
A+
