I had a switch like that, it would change between 2 full set of
keyboard, mouse and monitor (vga only, not dvi). I had a simple
mechanical switch, but professional ones with electronic control exist
and are frequently used in racks of servers. 

As for problems to the PC, if the operating system or graphical
subsystems communicats with the monitor to get screen resolution and
supported modes (it's called EDID data, iirc), it may default to some
safe low res (640x480 at 60Hz, maybe) if the monitor is disconnected when
the system starts. Or it may fail to start at all, you have to test that
to see what your OS does.
