The AppleColor High-Resolution RGB Monitor is a 13" (12.8" viewable) Trinitron aperture grille CRT that was manufactured by Apple Inc. from March 2, 1987, until October 19, 1992. The video cable uses a standard Macintosh DA-15 video connector and the maximum resolution is 640x480 but the Apple IIGS can not normally use this without a PC Transporter card (displays CGA graphics) or other video card. It could also use all the graphics modes of earlier Apple II computers. The complete list is as follows:

  • Low: 16 colors, 40 by 48 pixels.
  • High: 6 colors, 280 by 192.
  • Double-high: 16 colors, 560 by 192
  • Super-high: 4 colors, 640 by 200 or 16 colors 320 by 200. Can also use pallet swapping with up to 16 palettes with one pallet per line allowing 64 or 256 colors total on screen, but only 4 or 16 per line.
  • There also exists a technique for up to 3200 colors for a static image with 16 colors per line in 320x200 SHR mode.


  • Information on resolutions is taken from the Apple IIGS owner's manual.
