On Wed, 10 Mar 1999, I posted a summary with the following subject:
"SUMMARY: Attach Digital monitor to PC"
Since then, I have received some additional suggestions for one out
of the three issues the summary was referring to:
> <wesley_at_yelsew.com> mentioned that he is using a VRC21-HA attached to a
> linux x86 PC, using a 15-pin D-shaped connector at one end, and BNC
> connectors at the other (widely available in electronic stores).
>
> <eddie_at_thruput.co.uk> mentioned that he is using a VRC21-HA on a
> standard VGA card.
>
> Older Digital monitors were fixed-frequency jobs that will work only on
> one setting. Finding that setting may be a problem unless you've got the
> technical specs for either the monitor or the system.
> A couple of pages containing info on connecting fixed-frequency monitors

The VRC21 is indeed a multisync monitor and it will support most
frequencies up to 1280x1024 with 72Hz refresh. My VRC21 do have both BNC
connections and a standard PC 15pin dsub contact.
Unforunately I can't find the doc's but I did find a documentation for
a frame buffer card (ZLX-E2) that states that a VRC21-HA can use the
following settings
1280x1024 72HZ
1280x1024 66Hz
1280x1024 60Hz
1152x900 66Hz
1024x768 72Hz
1024x864 60Hz
800x600 72Hz
800x600 60Hz
640x480 73Hz
640x480 60Hz
These are the settings of the graphics card but the monitor might
accept other frequencies too.

I am writing this sitting in front of my VRC21-HA on my PC. I have
tested various resolutions/refresh rates on it and I am currently running
1600x1200 at 65Hz. I have also tested and used it at 1280x1024 and lower at
75Hz (much better regards flicker). I am running it off a Matrox Millennium PCI
card, but I see no reason that any other card running within these figures
should not work. As regards cables I have used a number of 15pin VGA -> 5xBNC
leads, all of which seem to work, but the picture is affected by the quality of
the lead. At 1600x1200 I have to use a good cable to stop ghosting and
misalignment etc..
Sadly the manual doesn't have the specs for max Horz and Vert refresh
rates. From my tests I estimate the maximum refresh rates to be;- Vert > 75Hz
and Horz 81kHz. The LED combinations for setting the picture geometry (taken
from the manual) are given in the following table:-
1 means LED on
0 means LED off
* means LED Flashing
1 0 0 0 0 Horz Position
0 1 0 0 0 Horz Size
0 0 1 0 0 Vert Position
0 0 0 1 0 Vert Size
* 0 0 0 1 (1) Colour 1 9300K white temperature
0 * 0 0 1 (1) Colour 2 6500K white temperature
0 0 * 0 1 (1) Colour 3 Adjustable white balance
1 1 0 0 1 Colour 3 (Green gain)
0 1 1 0 1 Colour 3 (Blue gain)
0 0 1 1 1 Colour 3 (Red gain)
1 0 1 0 1 Rotation
1 1 0 0 0 PCC-Amp-Fine
1 1 1 0 0 PCC-Amp
1 1 1 1 0 PCC-Phase
1 1 1 1 1 Key Balance
0 0 0 0 0 Pin Balance
(1) Select between these items with the + and - keys.
The monitor accepts sync on green, composite or separate H and V sync and is
compatible with EPA VESA DPMS. Regarding connections, the manual says that the
15-pin D-sub is not supported and should not be used.
