Is there a KVM switch with three ports and switching not only PCs, but also terminals?

Question

KVM

I ask you to advise a KVM switch with a tricky device: there are two PCs (under Linux, so software switches may not work), each of these PCs has a monitor, and there is a Win7 gaming computer without a monitor. You need a device that will allow you to use either your PC or a gaming computer using a monitor / keyboard / mouse in each of the two places.
Usually, KVM switches are designed for one user and many machines (usually servers). Is there what we need, and at a not very expensive price?
Would like to buy a switch on aliexpress

Answer 1

What's the problem? 2 dual-port KVMs. 2 video outputs of a gaming computer - Clone mode, USB keyboard and mouse

The comment reminded me of an old joke: A man approaches a policeman and says:
- Let me tell you a political anecdote?
- Don't you see - I'm a policeman!!!
- Nothing, I'll tell you slowly and twice.
So, the second time, and slowly:
We take 2 (two) such 2-port switches. We connect the first switch to the first computer with Linux, and to the first video output of the gaming computer, the second switch to the second Linux and the second video output of the gaming computer. We translate the video outputs of the gaming computer into the "clone" mode. It turns out what they wanted - on any of the 2 places you can connect either to your Linux or to a gaming computer.
