Maybe not all lines are connected to the VGA connector (which is used for monitor ID, among other things). These additional connections are not required in 99% of cases. It works with computer video outputs and I do it with multiple machines. For the money this is a bargain. Metal body, beautiful positive switches and pure iron. I don't see any of the resolution issues that are common with software and/or more complex switches. I have several different switches and if you just want to switch monitors this couldn't be better.
