I'm no electronics buff.. but i guess it depends on the outputs of the dvd player and the inputs of the monitor you have or intend to get.
Personally I bought a 46" flat TV some years ago and matched it's RGB input to my PC's RGB output (probably be HDMI now) so I can watch DVD's with the PC's player, watch internet streamed stuff and back in the day actually see the numbers on a many columned spreadsheet.
Terrestrial reception here is pants so we don't bother or have a licence and the legacy sat dish here isn't connected.
There's also a good chance your laptop has appropriate outputs for a monitor
