Supported PC-Graphic chipsets

S3 Vision 864

I have used this monitor with an S3 Vision 864 Card (manufactured by DEC) with 2 MB of graphics memory installed and it runs smoothly with no problems.
Operating system: Linux with XFree 3.3.3.4 on a DEC Alpha.

S3 Virge DX

I have also used this monitor together with two different 4MB Virge DX cards and it worked with no problems. The screen was stable and flicker-free in most resolutions.
Operating system: Linux with XFree 3.3.3.4 and Windows98 (worked in 1024x768@75Hz with the help of this excellent tool).

Matrox Mystique 4MB/170MHz RAMDAC

Thorsten Kuhn has figured out that you can drive the 6091 with some (probably any) Matrox MGA card under Windows NT. All you need is his patches MGA.MON file. To install it, do the following. If you have any questions about that thing, don't ask me but him!!!
Remark: I've tested this with Windows 98 and it worked - the monitor displays a large (fullscreen) stable picture.
Die Datei MGA.MON aus C:\Programme\Matrox MGA Powerdesk\Mon\mga.mon (Default Pfad) durch die hier downloadbare MGA.MON ersetzen.
Danach Matrox Anzeigeeigenschaften öffnen (ICON Startleiste).
In der Monitor Auswahl auf MGA-Monitor umstellen (Monitor Datenbank wird neu
eingelesen).
Es müßte nun ein Benutzerdefinierter Monitor 1024x768 erscheinen.
Hier kann man dann alle Auflösungen testen.

English translation (ok!, it's rather poor ;-) ):
You have to put the file MGA.MON (download it here) in c:\Programme\Matrox MGA Powerdesk\Mon\mga.mon (or c:\Program Files\Matrox MGA Powerdesk\Mon\mga.mon) if you don't find it, simply search for the file mga.mon and replace it with the downloaded on.
After that open the dialogue "Matrox Displayproperties" and change the monitor selection to "MGA-Monitor". You should see an "User defined" (Benutzerdefinierter) Monitor. Select it and there you go.
 

Some alternative settings for the Matrox cards can be found here (http://www.lysator.liu.se/~jonass/mgamon.html).

i740

I recently got an e-mail from John Stewien (stewien@box.net.au), who told me that he is using the monitor with an generic i740 card under Windows NT.
Here are his emails describing it:
First e-mail:
Hi there Sven,

just letting you know that I'm running Windows NT, and I'm driving an
IBM 6091 19 off of a generic i740 based card. I'm achieving this with
the aid of a little utility called Powerstrip, written by Entech Taiwan.
I've it running by telling Power strip that I have a LG Electronics 2010
monitor, with +ve Horizonal polarity, and +ve vertical polarity (the
adapter cable I got a a little box on it through that may switch the
Horizontal, cause from what I understand I think the IBM 6091 likes -ve
horizontal polarity). Anyway, I get 1280x1024x60Hz, and 1024x768x77Hz
(using the mode 2 switch position). Its a pity windows NT doesn't easily
allow tweaking of the video modes.

Regards

John

Second e-mail:
Yeah sorry, I didn't have the URL handy before, so I didn't include
it, but I've got it now, its http://www.entechtaiwan.com/ps.htm
[..]
It supports most video cards, and they have a beta version out for the
Voodoo3, TNT2, Savage4 and Rage128.

Bit tricky to set up though, as at the moment I need to boot NT, run
PowerStrip, choose my settings and then apply them to the screen settings.
I've got an old 14" monitor sitting here, I'm looking for an adapter than
will let me plug it into the 5 BNC outputs on the back of the 6091.
Alternatively, I've also got an old Diamond Stealth 64 installed in the
machine, but even though NT is meant to support multi-monitor, I can't work
out how to get both video cards working at the same time, I can either boot
up on one or the other, but not both at once.

I guess I'll work out something.

- John
 

You can download the mentioned tool Power Strip from http://www.entechtaiwan.com/ps.htm .

Other cards that may work

The following cards should work, too (though it has not been tested by me):
• miroCrystal 20SV (S3 Vision 964)
• Cirrus Logic 5440
• ATI Graphics Turbo pro
• Tseng ET4000w32p
• Matrox Millenium ( of course :-) )
• Diamond Stealth v-64
• Elsa Victory 3DX
• ATI Mach64
• Asus AGP-V3400TNT (at 1152x864@75Hz in WinNT)

Summary: Tools that may be helpful for Windows

• Power Strip http://www.entechtaiwan.com/ps.htm .
• IBM sync for Windows by Per Lindh (to use this: select 1024x768 at 75 Hz refresh rate and after changing to that resolution start this little program. You may have to run it again, after some application has changed the resolution (eg. DOS-Box or DirectX Game)).
