#158696 - Not simple for quality signals
Responding to: ???'s previous message
Are you talking about an digital or analog switch?

A screened relay built for video signals is not cheap.

And a silicon video multiplexer chip also costs money (including shipping costs).

In the end, a DIY video switch will probably be quite expensive or producing lackluster video quality.

The signals in a DVI-D cable are digital. But that does not make it trivial to switch them. It isn't TTL signals but low-voltage differential signals. And the signal frequency is quite high. You have about 1V peak-to-peak, and I think you have 1.65Gbit/s transfer rate.
