3 DualH2Go --> 4 screens accelerated in Vista ?

GSalden · Post by **GSalden** » 13 Dec 2008, 08:35

Hi all,

Just wondering if the following setup would work for FSX.

1 DualH2Go connected to the graphics card and the other 2 connected to the first DualH2Go.

Would this work in Vista ?

Nb
I know that when using XP you can connect 2 DualH2Go to one graphics card ( 1 DualH2Go connected to one DVI/VGA out ) and this really gives you 4 3d accelerated screens.

If you haven't bought the dualH2go yet then just get the triplehead2go to power the 3 monitors and then the 4th one will be connected to the second dvi out of your GPU. This is what I have too. So I'm using both DVIs of my GPU. I play FSX with 4 monitors using this set up.

If you have 2 dualh2go, I think you can connect them to each of the DVI. But I'm not sure though.

No need to have 3 dualh2gos.

If 3 dh2g work like that, it would let you show windows a single 3d accelerated window, 2 + 2nd dvi wouldn't, not for most games save for the few exceptions that care about multiple monitors like fsx.

Considering a single dh2g or th2g has problems working by itself, I wouldn't bet on 3 playing nice together though.

The 4 monitor setup will be used for Flight Simulator X.
Therefor all monitors need to be 3d accelerated.

When using a TH2Go + an extra monitor , the last one will not be accelerated and the framerates will drop at least by 30%.

I like my settings very high , so the extra monitor connected to the same card is not the way for me.

Because of that I was thinking about this 3x DH2Go setup.

Anyone has other suggestions ?

Run a separate window the 4th screen.

Like I wrote before : that windows would not be 3d accelerated.

Any other suggestions ?

The point of Surround Gaming is aspect ratio over resolution.

Whats the practical use of 4 screens? Have you considered 2 CRT projectors?

Why would you split the image of a double res virtual monitor down the middle? 1 DH2G is for example 2560x1024 to Windows, inputting that to 2 DH2G would give you at best 640 horizontal pixels stretched across 4 screens. Neither Windows or Matrox GXM knows about the 2 later DH2G in chain.

Without knowing what you expect on each screen, you arent going to get very useful suggestions.

hmmm. I think you're opting for a mini flight simulator. You're monitors will act as the windshield and the windows of the cockpit. If that's the case, I suggest you ask the flightsim community. I think they know better. I actually wanted that set up too.

So, what's the problem?

Adding an undocked window to make 4 screens will make you loose 3d acceleration and about 35-40% framerates.

And you've actually experienced this, or have heard others experience with this? Or is this an assumption you are making?

If you lost 3d acceleration all together, then FSX would have to run in software mode. I'm pretty sure that's not even possible.

I suspect it won't work because I don't think you can daisy-chain these units. Each has a set max input and output resolution. Your best bet (other than the undocked window) would be go back to XP and use span mode. At least that's what worked for me.
