The above specs show only maximum resolution when used with a plain Apple
IIgs. It has an interlaced mode which allows you to display 640x400, though it
isn't going to be easy to look at for long periods of time. You can see the
interlaced mode if you have a VOC or Second Sight card.
The viewable area on an Apple IIgs is probably a fair bit less than 12"/
11.5" viewable when you take into account all the space reserved by the border
in all display modes. That probably makes it about 10" viewable or so. If you
hook up another video source (e.g. a SuperNintendo) then you can use the entire
11.5", including what would be the border area.
