- | Funny you ask this -- I was on the phone today with SGI Express about this
- | very issue. SGI does make a cable that is a "13W3-to-BNC" (Part number
- | 0188105001). I think the cost is about $100 (but don't quote me :)
- |
- | The small pins are used to code for the monitor type. They form a
- | passive circuit so they don't have to be connected BUT if they
- | aren't connected, the Indigo defaults to the 19 inch Hitachi.
- | If you have a smaller SONY monitor (like us) this is not good :-(
- | Someone from SGI correct me if I'm wrong, but I think I was told that
- | you CAN'T set the monitor type in software. (Doesn't sound right but
- | that's what I'm told).
-
- You can, by setting some environment variable, but I doubt that it
- is documented anywhere what it is for all the various monitors
- (and I don't know myself).
