Not all Macintosh video sources support the Macintosh 12-Inch RGB Display. The following Apple video outputs support this monitor:
- Macintosh Display Card 4*8 and Macintosh Display Card 8*24
- Macintosh IIci built-in video
- Macintosh IIsi built-in video
- Macintosh LC built-in video
- Macintosh LC II built-in video
Notes:
All previous video cards do not work with the Macintosh 12-Inch RGB Display. At the time these cards were developed, the timing for the Macintosh 12-inch RGB Display was not known and, therefore, does not support the proper video signaling.
The Macintosh Display Card 8*24 GC does not work with the Macintosh 12-Inch RGB Display. The card is designed for high-end systems, and the Macintosh 12-Inch RGB Display is for inexpensive systems.
