How to implement DVI-I switching by means of a relay?

Question

Arduino

Kind time of the day, tell me the idea of ​​\u200b\u200bimplementation. The bottom line is, there are 2 PCs (system units), Arduino, peripherals (monitor, mouse, keyboard, speakers). Both PCs are on, you need to switch between them on the fly. The idea was in relay switching using Arduino according to the scheme:

But I can’t even imagine how many relays will be needed, is there anything compact?

Answer 1

Relay? For rent burn your iron.
Can KVM be easier to buy?

Answer 2

Both PCs are on, you need to switch between them on the fly.

And there is also "terminal access" - connection from one computer to another, TimWiver, RAdmin and similar programs.
It is also quite possible to use it, depending on what tasks are spinning on the computers.
