  Rick McLeod <mcleod@esprit.esd.sgi.com> writes:  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.

  Clinton Keith <clint@art.ray.com> adds his implementation details:
  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
  24X 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 a workstation supply vendor) which went to the
  monitor.

  I then set up the 24X to provide -/- sync voltages and selected the
  highest vertical and horizontal scan rates I available.
  Unfortunately, the monitor refused to display 640x480 (pride?) 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.

  bkonjkav@aol.com adds: PCG makes an IBM-compatible graphics card that
  runs RGB (fixed frequency) SGI monitors on a PC. For more info call
  800-255-9893 or 310-452-8470 and ask for Ben at ext. 150.

  Joe McCarthy writes: Software Integrators has graphics cards for PCs
  which drive SGI monitors just fine. All SGI monitors are supported,
  both fixed frequency and multi frequency. The Mercury X1 and X2 cards
  can run sync on green and they supply the cable. You can call them at
  800-547-2349.
