I have found a manufacturer that seems to have an adaptor to allow me to use
my HP A2094 monitor with my standard PC for only $30.00.
Could this actually work ?
I am not a monitor expert so could someone tell me if this could work by
adding composite sync on pin 13, and on green pin 2 ?
Looks to me that It would only be MONO if this is done ?
Here is the information from their site:
PC Sync Adapter (Cost $30.00)
HD-15 Male to HD-15 Female adapter provides
composite sync (pin 13) and sync on green (pin 2).
Here is the standard pinouts for a VGA video card that I found:
VGA DB15-S Female DB9 Female
15-pin 9-pin assignment
1 1 Red
2 2 Green
3 3 Blue
4 - Monitor ID bit 2
5 - N/C
6 6 GND (red return)
7 7 GND (green return)
8 8 GND (blue return)
9 - N/C
10 - GND
11 - Monitor ID bit 0
12 - Minitor ID bit 1
13 4 Horizontal Sync
14 5 Vertical Sync
15 - N/C

It doesn't solve the timing problem, just the wiring. As long as you
can get your software to program the video card for the right timing,
it will be usable. Note that this means that you won't be able to see
standard VGA settings nor text modes (e.g., the BIOS settings, DOS
command-line-only, etc.)
There are special video cards that can support a fixed frequency monitor
even in text modes, but I'm told that they cost about $200.
As mentioned previously, even with a "standard" video card, XFree86 under
Linux or FreeBSD can be configured for any video timing you need. However,
you won't be able to use the display outside of X.

It will help you just as much as wrapping a rubber band around the
video cable. Sure, the rubber band wont do a damn thing for you, but
it will cost a lot less than $30.00 ;)

You dont need a sync adaptor. Your monitor has 5 BNC connectors, and can
thus accept separate sync. This is a GOOD thing. Especially since your
video card generates separate sync.
Now, you say that some source mentions that the monitor is not VGA
compatible. Most likely, this is because the monitor doesnt support
a 640X480 @ 60Hz mode. When IBM compatible computers boot up, they always
use this video mode, and later in the boot sequence they switch to
whatever mode you specify.
SO. IF this monitor is going to work at all, what you need is a video
cable with 5 BNC connectors on one end, and a HD15 connector on the
other. If the monitor doesnt support 640x480, then you would have to use
another monitor to set windows to the correct resolution and refresh
rate, and then switch monitors. Thereafter, when the machine is booted up,
the monitor would not sync up until the boot sequence reached the point where
it changes to the correct resolution and sync rate. Of course, if something
goes wrong, you wont have a clue whats wrong until you switch monitors...
Dont pay more than $15 for the video cable, and make sure it comes with
a toroid of some sort. As long as you're sure your IBM video card can be set
to that maximum resolution and refresh rate that the monitor can handle,
I would say this has an excellent chance of working.
