Suns use different pins for sync than SGIs (and Suns usually use
composite sync, while SGI use separate H and V), and SGIs also use some
pins for monitor type sensing. However, quite a lot of Suns and most
SGIs also provide sync-on-green, so if the monitor supports that, and
the other signals don't cause confusion, it should work.
Contrary to popular belief, most SGIs from the Indigo onwards do not
require a SOG monitor.
Sorry, I don't know what the pinouts are for HPs or IBMs (apart from
R,G, and B). If anyone cares to tell me, I'll add the info to my crib
sheet:
13W3-SGI
================
pin A1 - Red/R-Gnd
pin A2 - Green/G-Gnd
pin A3 - Blue/B-Gnd
pin 1 - monitor type 3 (ground this on old machines, leave open on
Indy etc)
pin 2 - monitor type 0 (LSB)
pin 3 - Composite Sync
pin 4 - H Drive
pin 5 - V Drive
pin 6 - monitor type 1
pin 7 - monitor type 2 (MSB)
pin 8 - digital gnd
pin 9 - digital gnd
pin 10 - digital gnd or Sync 2
13W3-SUN
================
pin A1 - Red/R-Gnd
pin A2 - Green/G-Gnd
pin A3 - Blue/B-Gnd
pin 1 - n/c
pin 2 - n/c
pin 3 - sense 2
pin 4 - sense ret
pin 5 - Composite Sync
pin 6 - n/c
pin 7 - n/c
pin 8 - sense 1
pin 9 - sense 0
pin 10 - C-Sync ret
For Indy, Indigo2:
MonID monitor guessed
111 no monitor (defaults to lowest res, lowest refresh)
110 Single Scan 1024x768 60Hz 15"
101 Dual Scan 1280x1024 & 1024x768 60Hz 16"
100 Idem 19"
011 MultiScan 1280x1024 & 1024x768 21"
010 1280x1024, 76Hz, 16" (82 kHz line freq.)
001 DM-20 MultiScan 1280x1024 76Hz 19" or Single Scan Sony
1280x1024 72Hz
000 1280x1024 60Hz only
for older hi-End:
MonID
111 No monitor
110 Single Scan 1024x768 60Hz 15"
010 MultiScan 16"
