Right. I'm going to have one bit to select the monitor type. With a
little "adapter" board it'll switch the low-voltage inputs automatically.
Using a few more lines I can control a pair of digital potentiometers with
a couple op-amps that act as a width and height control that can be set
 from the menu system. Kinda neat. The same board can be used as a Wells
Gardner adapter board as well...
