I have one of these in my home office. Just press a button to switch from my work laptop to my PC, including all peripherals like speakers, webcam, mic, etc. My only complaint is that the audio behaves a little strangely. It buzzes and pops loudly when switching and during startup, and I’ve had to customize my audio configuration to account for some of the quirks, but it’s painless at this point.

This is the one I use https://www.avaccess.com/products/4ksw21-dm/

Do you know of any that support HDMI 2.1 properly for 8K 60 Hz monitors? I currently just have a USB switch and two HDMI 2.1 cables, and manually change the input on the screen each time.

Don't do that, do this: https://haim.dev/posts/2020-07-28-dual-monitor-kvm/ - free and works great!

I have the Aten CS1944DP, a dual screen, 4K60 DisplayPort KVM with the ability to drive 4 computers. I use two 27” 1440p144 monitors.

Cable management is a bit of mess, but it’s fantastic to be able to switch between personal, work, client and something else computers with the flick of a button (or keyboard shortcut).

I’ve not heard or seen any 8K KVM.

I've thought about these but don't want to mistakenly type something crazy meant for my friend groupchat into my work computer.
