[SPARKY70]

hi, i was wondering about the actual size of an arcade monitor.  does a 25 inch arcade monitor have 25 inches of viewing, like a tv would. or is it like a computer monitor (my 19 inch monitor has 18 inches of viewing)....thanks///sparky

The size refers to the diagonal measurement.  The viewable area is slightly smaller than the total on any tube.
