Yeap! This is my setup for MacOS and Linux with display port: KVM Switch Dual Monitor DisplayPort 1.4 8K@30Hz 4K@144Hz 2 in 2 Out,DP1.4 KVM Switch and 4 USB3.0 for 2 Computers,Backnward Compatible DP1.2 with DP+UBS Cables and Wired Controller https://a.co/d/5A3IG5P

Under the Extend mode, it says it requires dual-graphics card. What does that mean? Guessing it's an odd translation.

I think it just means if you want to kvm with two monitors over DP you need two DP ports on each computer.

yeap, this is how my setup is. Two DP ports are occupied.

The only ones I know of are the ConnectPRO ones. I have a UDP2-14AP, but it's really finicky. It works great with some systems and monitors, even at high resolutions and refresh rates. But other systems (for me, my MacBook) involve several blank-and-move-all-your-windows-around cycles before it settles and becomes usable after switching to it. I suspect this might be a monitor compatibility thing with the Mac, but I'm not sure.

Anyway, it's pricey and picky about compatibility, so it's hard to recommend, but I'm not aware of anything comparable in terms EDID emulation and support for high res/refresh modes.

Edit: Based on a sibling comment, the situation may have changed and there may be comparable ones around!

TIL, thanks. I think they should make that doable in one click, though.
