Anything that can do better than 1080p is insanely expensive or cheap and flakey. I gave up looking and just got a new monitor with a KVM built in.
Most have one USB-C with 65w+ PD which includes the keyboard and mouse and then add 1-3 more slots that have HDMI and/or DisplatPort + USB-A for the keyboard and mouse.
Keen to know what you’ve tried. Or if anyone has found something good that isn’t silly expensive or cheap and dodgy.
Be the change you want to see.
And to answer your question, about as long as it takes to have 2 or 3 of people like them as your boss/lead.
