Pete's OpenGL and multi monitor

**Kane** · March 24th, 2003

I run my machine with an nVidia geForce 3 with a Voodoo 5 in tow in multi moitor mode.
The problem is that this means that although I can use his d3d plugin fine, the OpenGL plugin fails to initialise in full-screen properly. I get audio, and the desktop res has changed, but I get no picture. If I disable the second monitor it's fine.
Any idea if there's another way to get around this?

This won’t help much, but OpenGL does work fine on my three monitor / two ATI card setup. So it’s at least possible to use OpenGL with multiple displays.

Have you tried disabling hardware acceleration on the second monitor? That’s worth a shot.

**Kane** · March 24th, 2003

Update on this, it only does it if it's set to a rez other than my current desktop rez...

0_0. you answered this on ur own website. just start up OGL in windowed mode and use alt+enter.

**Kane** · March 27th, 2003

...That fix is for ATi card with previous drivers on Pete's OpenGL 1.68 and 1.69. It does not help with my problem, kthx bye.

LOL. Okay if I'm gonna help you let me get something strait. So you are only using 1 moniter right?

No. My GeForce is strapped to my 19" and my Voodoo to my 17"

well i'm lost already. sorry dude. (not too smart in the brains department)

There is no solution for OpenGL with MSWindows multi-monitor mode. I've descriped that in my very first fairy tale (can still be found on my homepage), and there is also a MS knowledgebase article about it. As long as the multi-monitor mode is enabled, Windows falls back to the MS software OpenGL drivers.

Snu · March 27th, 2003

ATI seems to have found some way around the problem — OpenGL works fine with my three monitor setup, even if the desktop and game resolutions differ. The picture can only go on the main monitor, but that’s okay with me.

**Kane** · March 27th, 2003

Oh OK. Thanks for the info Pete, however, I'm not sure that is correct on XP as I can run Quake and Tenebrae no problems. If possible, could you give us a link to the Knowledge base article, as I couldn't seem to spot anything.

**Pete Bernert** · March 27th, 2003

>I'm not sure that is correct on XP

ah, no, as far as I know WinNT/2000/XP should be able to do OpenGL hw/accelerated in multi monitor mode (if the gfx card drivers support it). Only Win95/98/Me had the software fallback (and there was no way around it).

edit:
funny enough, here's a FAQ entry from nVidia:

why dont you just get a better video card kane? like a radeon.

cause i can run dual monitor mode with ePSXe perfectly fine :/

**Kane** · March 27th, 2003

>why dont you just get a better video card kane? like a radeon.

Because I don't like ATi after they badly screwed me at least once already
if I were to replace this card I would get an nVidia
Because I don't need a new card
Your ATi is multi monitor on a single card, and I expect you would have similar issues if you had another card like the Voodoo 5 PCI

Snu · March 28th, 2003

I should have said — Yes, my operating system is Windows XP Home SP1.

Getting ATI cards isn’t a cure to all multimonitor ills. My experience is that the ATI cards do have better odds of working together than nVidia’s. (Old Matrox cards have the best record — Both Matrox PCI cards I’ve used work just fine with any AGP cards I tried.) But I’d strongly recommend that anyone planning to use multiple video cards make sure to get the card from someplace with a 100% money back policy. That way you can return it if it doesn’t work well with your setup.

Kane,

Did you try disabling acceleration on the secondary monitor? That has solved a lot of problems for me in the past.

Kinda defts the object of me running with a Voodoo 5 in there, doesn't it? If I were gonna do that, I'd plonk one of my plethoria of S3 trios in there and use the Voodoo in my backup machine. It takes just a moment to disable the second card, but it'd just be nice if I didn't have to.
