* Connection as shown wil allow multiple resolutions up to 1152x870. Reverse diode to limit resolutions to 1024x768. The Mac Centris, Quadra, and later systems frame buffer determines what type of display is attached to the video connector by examining the state of 3 sense line pins.
The Mac Quadras, Centris series, and later models should support any display, whether from Apple or from another vendor, that meets one of the following specifications:
STANDARD SENSE CODES (1 or more of the sense pins grounded):
Notes:
1) Sense pins 4, 7, and 10 are referred to as MON.ID1, MON.ID2, and MON.ID3 in the Macintosh pinout table or SENSE0, SENSE1, and SENSE2 in pinout tables for the video connectors. A sense pin value of 0 means that pin should be grounded to the C&VSYNC.GND signal (pin 11); a value of 1 means do not connect the pin.
2) Extended sense codes will be examined if the following sense code is detected: 1 1 1 (no sense pins grounded).
NOTE for extended sense codes: Sense pin pair value of 0 means those pins should be tied together (as opposed to grounding 10, 7, or 4 to pin 11); value of 1 means leave open. DONT wire any of these pins to ground.
