Yeah… Not sure of your model (I have the U4025QW), but mine is so close to perfect as a KVM between a Mac and 2 PC’s, if only the KVM had one more USB output port.

It takes 3 video inputs, but only 1 dedicated USB output. But oh, one of the video inputs is really Thunderbolt, so you get USB over the same cable and it works… but only if your machine supports this (for many laptops this is fine.)

But that’s 2 machines max in the KVM, while the monitor has 3 selectable inputs…

It would have been nicer if they could’ve added one more USB output, so you could have KVM match the display input for 3 machines with a single toggle.

(I have a Mac, a work desktop, and a gaming desktop, and I can toggle between the Mac (thunderbolt) and one of the PC’s, and the kvm input will follow the display’s. But I have to pick which PC I want to plug the downstream USB cable into… so I bought a little $15 USB A/B switch to help. So Mac keyboard always works, but when switching between gaming PC (hdmi) and work PC (DP) I just have to remember to toggle the A/B switch along with it to make the keyboard go to the right host.)
