For some reason I assumed this was a TV, but I just googled that model #, and it's a PC monitor, not a TV, so it's definately not S-video or Composite, just a plain old 19" VGA monitor. If you go looking for one, make sure you're in the right part of the store!
BTW, a 19" PC monitor is not as big as a 19" arcade monitor. 19" arcade monitors have a screen about the same size as 21" PC monitors.
