[comp.sys.sgi] 1024 x 768 video from Personal Iris?

jsp@milton.biostr.washington.edu (Jeff Prothero) (09/28/90)

Does anyone know how/if you produce 1024 x 768 video on a Personal
Iris?  I understand the PI is available with a Sony monitor which runs
at this resolution, but am unable to find anyone who has such a beast,
any manual reference to putting the PI into such a video mode, any
header file defining such a mode, or any hint that a special video
board is required/available.

(The problem is that the film recorder we bought for our Iris 3020
(remember them?) maxes out at 1024x768.  We're now using PIs
everywhere, and would like to use the film recorder with them.  We
can't afford a new 1280x1024 film recorder, and it looks like our 3020
is headed for the junkheap.  So a hardware and/or software hack to
temporarily (or even permanently) set a PI to produce 1024 x 768 video
would be very welcome just now...)

 Thanks in advance,

 -- Jeff

The PI with the 14 inch monitor has different video hardware.  I don't know
what is involved in changing from one to another.

Newer versions of the Personal Iris (those shipped since the middle of
1989) have a nine pin connector in addition to the standard RGB BNC jacks.
This nine pin connector is for the 14 inch monitor option, which is
1024 x 768.  So if you have a machine with one of these connectors, you
are in luck.

Alternatively, you could switch to 30Hz high-res mode which your film
recorder should be able to handle (of course you won't be able to
see an image on the 60Hz monitor at the same time).
