QUESTION:

"Is there some equipment I can hook up to a mac mini that will let me output the control screen to a monitor and the video to the projector?"

ANSWER:

1. Matrox DualHead 2 Go or Matrox TripleHead 2 Go
   1. This is probably the best easy option for the Mac Mini.
   2. Dual Head to go $140 Plus shipping
   3. TripleHead 2 Go $250 Plus shipping
2. A scan converter with zoom feature
   1. You still have One "monitor" output, but you put the Video off to the side, say in 1/4 of the screen, and use the scan converter to zoom into that quarter of the screen,
   2. Then you have to build the controls in the other quadrants.
   3. If you run the monitor @ 1280x1024 the Quarter screen resolution will be 640x512 which is a bit higher resolution than composite video so you don't suffer that much loss. (unless you are using HD content)
   4. Problems with this are that
      1. Most scan converters suck on some level.
      2. They don't recall the zoom and pan settings when you power them down so you have to reset them each time.
   5. Scan Converter $60 - $170 for low end. ($500 - $2000 for high end)
