Vertical height is often adjustable, and even on quite pricey systems
you shouldn't think of taking measurements directly off the display.

640x200 is all that a IIGS provides in its display circuitry, unless
you add more display memory and other circuitry as in Apple's Video
Overlay Card (which uses interlacing that apparently many people think
flickers excessively on the standard Apple RGB monitor).  I don't see
how Duet could really have made any other choice, although it would be
nice if it could utilize the VOC when one happens to be present.

I fully agree that 640x400 is a sensible display resolution for a GS-like
system.  (I said that when the GS was first introduced!)
