> If you have multiple screens and a single screen KVM (fairly common) it will do the re-arrangement that you've experienced. With EDID support it keeps both output alive resulting in no re-arrangement.

Can you tell me some KVM switches that have a working implementation of that feature? I'm looking for one.

I'm still using a DVI KVM, because when I tried to upgrade to Displayport (years ago), I ran into the problem you describe and gave up.

I have a TESmart (TES-HDK0402A1U-USBK) from https://www.amazon.com/gp/product/B08259QL5J/ref=ppx_yo_dt_b... which works fine in this regard. This was probably the 4th DisplayPort KVM I tried due to keyboard issues with the others.

I'm looking too, but that one linked has HDMI out only, with DP and HDMI in. Don't you lose the benefit of DP with this setup?

It has been OK for my needs, but I think you are best getting the KVM and returning if it doesn't meet your needs. I'd probably be more concerned if this was for my photography or gaming machine. For a work setup it has been fine for me.
