the issue is to get running surround gaming games (that are displayed on 3 displays) with 2 nvidia vga cards non sli and without matrox triplehead2go.
1 display, the middle one sould be connected to 1 card and the 2 other displays (richt and left) are connected on the other card.

I talked about this with Judas but I did not get it set up properly.

The started game does only run on the vga card set as primary.

Here card with display 1 is primary and the (2 other) displays 2+3 connected to card 2 are in Dual Head mode:



Here card with display 1 is primary and the (2 other) displays connected to card 2 are in horizontal span:


@Judas: How did you set up your working system?

@all: Does anyone have another idea?

I used the Nvidia Drivers Gui to span across 3 monitors (SPAN).

However i'm come to the understand that i had somehow gooffed up the nvidia drivers or had a set that were a fluke in getting it working.

ATM i have zero nvidia cards to play with and i'm not sure when i will..

but this was with 2 nvideo 7900's on a Asus A8N32-SLI with the latest bios. And i think before nvidia put the smack down on the ULi chipset patch trick.

In any case, you can't do the spanning within the normal Windows Display manager, you need to get into nvidia's... and go from there... (dammit i wish i had an nvidia machine atm to see if i could get it working)...

BTW, what happens when you running in windows mode and drag it across.. or just windows mode on that spanned monitors....?

The Problem is that I can set horizontal span only on the vga card, that is connected to 2 displays.
How do I set it?
Does windows saw your 3 displays as one 3840x1024 or 3072x1024 ?

I havent tested that!

Which game did you test?

I thought and I am pretty sure I read that Fullscreen Direct X games always default the the Primary monitor...That advice is good I think You may be able to put the game in a window and stretch it..other than that I think your out of luck...don't quote mer on that though..hope that helps.

the problem with ATI drivers.. is that when stretching it.. the CCC itself is limited to only seeing and selecting monitors on a single video card (2). Where Nvidia, i don't think i had this problem as it showed all the monitors connected in a similare to windows display manager stype and right clicking on them resulted in bring up the span availablity option for each display.

Now saying about the ATI driver, if stretch mode is enabled across 2 displays, running in windows mode acts like it's running 1fps. Which results in pretty unbeleiveably uselessness. However running full screen across the 2 is perfectly fine. Those are the limits with the ATI setup in which you can find in the Radeon Driver Forum dubbed "Catalyst Maker, Can I...".

Now for the nvidia side, i never had a problem running in windowed mode, (am i lucky?)... And i had no problem stretching it either (Age of Mythology) across all 3.

Try UT2004 in D3D mode then hit ALT+ENTER to go from full to windowed mode. Then manually stretch it.

If it's chopppy as hell, shut it down, fire it up again in full screen, turn it to OPENGL mode and then repeat and see if it's still choppy as all sin..

Now, ALT+ENTER doesn't work for all games... but majority of them they do. Fiddle with it.

All displays MUST BE the same resolution (3x 1280x1024 for example so that total is 3840x1024) Course when running windowed mode, you do not always take full 3840x1024 screenshots due to running a windowed mode.

additionally... Try various options.... anything that looks triggerable....

If leaving fullscreen mode the game seems to be not 3d accelerated and the frame rates are really bad.
Some games do not allow to be manually stretched.


Does Ati (now) have a functional horizontal span when running only with 2 displays?
