SGI monitors to PCs

I recently researched this and heres the scoop:

GOOD NEWS FOR O2 USERS: "The monitor that SGI ships with the O2 has an
HD-15 Super VGA-type connector on it and can be connected to most SVGA
boards." (Thanks to the SGI FAQ group at Texas A&M
<sgi-faq@viz.tamu.edu>)

For other models, here's what the experts have to say:

* "This depends on the SGI monitor. PCs want multifrequency/
multiscanning/multisyncing monitors. Earlier SGI platforms supplied
fixed frequency or dual scan mode monitors. These will not work on PCs.
Some current SGI machines (Indy, Indigo2, Onyx) ship with multiscan
monitors. These will most likely work with a PC, but make sure that the
monitor gets the proper sync signal." (Thanks to Rick McLeod
<mcleod@esprit.esd.sgi.com>)

* "The GDM-17E11 works on my PC with a Diamond Speedstar 24x. I
used a VGA connector that brought out the RGB V and H sync lines from
the card into BNC connectors (commonly avaliable at a local computer
store). I connected the V sync H sync and Green lines together and
connected this line and the Red and Blue lines to a BNC-to-DB13W3
connector (bought at a workstation supply vendor) which went to the
monitor. I then set up the Diamond Speedstar 24X card to provide -/-
sync voltages and selected the highest vertical and horizontal scan
rates I available. The monitor refused to display 640x480 (out of pride
perhaps?) but did well at 800x600, 1024x768 and 1280x1024. There was a
slight greenish tint to the black areas of the screen. It seems as
though connecting the sync lines to the Green may have added a DC bias,
but the effect is minor." (Thanks to Clinton Keith <clint@art.ray.com>)

As was stated earlier, there are companies which make graphics cards
which drive SGI monitors (both fixed- and multi-frequency) on PCs. They
include:
