I found two SGI "granite" monitors

morning. Does anyone know if these will work with the SGI Indigo?
(XS-24 video card.) I tried them but I'm not getting any video and
I'm not sure if these are both bad or if they're even supposed work
with the Indigo. I checked the SGI and Indigo FAQs and can't find
anything about exactly what systems the monitors are compatible with.
Yeah, those should work just fine on the Indigo.
I assume your Indigo is known operational, and that you have a suitable
cable. Do the monitors just not display a picture, or do they not even
exit power-save?
I don't think it's even exiting power save. When I turn it on the power light
comes on and there's a click from inside the monitor. After a few seconds the yellow
power save light comes on and then I hear another click from inside the monitor. When I
turn the Indigo on, it powers up and plays it's tune so I know that it's started
but nothing changes on the monitor.
I disconnected the video cable at the monitor and looked for sync on pin 3 and found
that there was no sync* unless I started the Indigo with no monitor connected. (The sync
was 63.something kHz). If I then connected the video cable to the monitor both the yellow
power save and green power lights started blinking.
*I don't think the lack of sync on pin 3 indicates a problem. This monitor is
suppossed to Sync-on-Green. In fact, the lack of sync on 3 when I boot the computer with
the monitor connected may well indicate that the computer recognizes that this monitor
doesn't use a separate sync signal.
The computer is definitely working. After trying these monitors I plugged the video
cable into my usual monitor and everything worked exactly as it's supposed to.
I was wondering, if I use a logic pulser and pulse the green input on the monitor will
it generate random garbage on the screen? Any thoughts on that?
