I have a Dell U3225QE with a built-in KVM and 2 macs.

One connects with Thunderbolt only. The other connects with Display Port for video and USB-C for the rest of the built-in dock.

It's OK most of the time with the nipple switch. My one piece of advice is *avoid HDMI*. I learned after getting this monitor that the HDMI protocol is a petulant unstable little shit that does not tolerate renegotiation well. Get yourself a USB-C to DisplayPort cable.

I have had exact opposite experience WRT display technologies. I normally use USB-C <-> DP, but they are far more finicky than HDMI. I only use the former because the hub I have for my Mac doesn’t do 4K@120 Hz over HDMI.

EDIT: sorry, the reason is because the monitor has HDMI 2.0, so it can’t do 4K@120 Hz over HDMI. Otherwise, I’d use the Mac’s native HDMI port and be done with it.
