I am amazed that there is an ESP that can handle this and with just 32MB of RAM:

I own 3 JetKVMs, of which two of them stopped working, one of which doesn't boot at all and the other that never connects to network. The third I took out of service because the keyboard wouldn't send input when it was connected for more than a couple months. I'm sure the newer hardware is better, but I'm very unhappy with my JetKVMs.

It may be worth noting that this is not _that_ KVM, but this one: https://en.wikipedia.org/wiki/KVM_switch

I learnt this first myself from HN, a few months ago.

Are there any good KVMs for gaming? Right now, I use a capture card for video, connect the mouse directly to the destination, and use a piece of software called Deskflow to transmit my keyboard. But Deskflow occasionally crashes, so it'd be nice to have a hardware solution (also that can be used for BIOS/etc). And Deskflow also won't work if I install SteamOS, once Nvidia works.

I looked at making a solution myself, but for some reason, simulating a USB client device in software is extremely annoying, and requires specialized hardware that is also very expensive. So at that point, why not just get a KVM...

I frequently switch between 1080p and 4K for gaming since I don't like resampling artifacts. Never found a KVM that can handle 4K properly even for productivity. The mistake can be as basic as assuming a 100% scale factor.

I have an ATEN KVM [1] that gets a solid "it does the job" from me. Occasionally a connected computer won't pick up the K, V, or M, and I'll have to reconnect a few times.

I use it to switch between my work laptop and my personal PC, and for this situation 4K is a must have. That, and the choice of HDMI instead of DisplayPort, and things that would keep me from getting a JetKVM.
