Adapters can be absolutely fascinating when they work I find, this looks perfect for someone like me, I want to have a dual PC setup exactly like this so I can render on one machine then game while I wait for the frames to finish. My only issue is potentially dealing with monitor switching as I have two monitors currently but presumably this sort of adaptor takes care of that? Would definitely save a lot of money in the long run not having to do silly things like buy an extra monitor just to play games on.

Answered my question about monitors, It handles HDMI as well as USBs.
I had a KVM switch 20 years ago when I was a PC tech. That one had both USB and PS/2 for keyboards even. It worked great for hooking up whatever PC(s) I was working on at the time and letting them do their installing, etc.
I find it funny they call it a "game changer." KVM is old tech.
What I prefer now though? A wireless keyboard with a USB and a Bluetooth mode. I hook up the work laptop and my personal PC both to the monitor and just switch the keyboard. I used to switch the mouse too, but I ended up just getting two of them. It's way quicker. Extra bonus, these monitors are so USB feature laden it will charge my work laptop on the same cable as the video, so it's a single wire connection.
