Since the DVI has HDCP you can get the common HDMI to DVI cable and switch as needed.
I have a Dell ST2421L monitor connected to my HP desktop using the HDMI interface. I would like to connect a different HP desktop to the same monitor using one of the other connector options. Could I do this and simply switch between the input options using the monitor control panel so I could view whichever computer I am working on at the moment?
