Thanks for this BTW. I had a similar situation: DisplayPort ports on computers, DisplayPort switch, DisplayPort monitor. And of course, the windows jumping around every time I switched the monitor.

I tried and tried to find a pass-through EDID adapter for DP to no avail. All I could find were headless plugs meant to fool some server's GPU that it was attached to a monitor. So I tried to duplicate your setup.

I ended up going with different hardwaretried to do DP -> DP-to-HDMI converter -> HDMI EDID pass-through adapter -> HDMI-to-DP converter -> DP switch -> monitor. This worked OK for 2560 x 1440, but I also took it a step furtherwas still unreliable, failing about 10-20% of the time, leaving me with the same moving windows. SinceWhat I wanted to keep my existingfinally did was this: ditch the DP switch, I brought the and use an HDMI back to DP before reaching the switch instead. Here's my setup:

So, it's computerComputers with DP output -> DP-to-HDMI converter -> long HDMI cable - HDMI EDID pass-through adapter -> HDMI-to-DP converter switch -> DP switchHDMI cable -> monitor. I'm not running 4K, butI have been using it works fine at 2560 x 1440. Andfor 11 months now with solid reliability for the windows stay where they are duringmonitors. (Sadly, my old PS2-plug keyboard from the monitor90s sometimes don't switch successfully, but toggle back and forth fixes that.)

Here are the parts I used from Amazon:
