M1.9p is correct of course ...
You can disable the card like this ...

Click the image to see it full size ...


Then run the other 2 SLI.

If that don't work ... phone Matrox as M1.9p says ...

Nice 'MS Paint'-work Paddy :wink:

I have disabled my third grafix card. Even then I cannot get the matrox to work.

Do we have to do something special to make 24" monitors to work, because matrox cut me off telling me to use 19" monitors.

because matrox cut me off telling me to use 19" monitors.

... crazy.

Do we have to do something special to make 24" monitors to work,

Apart from set the resolution ... no.

Are you still getting ... no DDC communication ? ... is it detecting your graphics cards ?

Yes, My hardware is still not getting detected. Weird!!!

All very ... very weird ...
Try un-installing the Matrox PowerDesk software in Add and Remove Programs in Control Panel ...
Then re-install it ... make sure you have the latest one from here ... http://www.matrox.com/graphics/en/support/drivers/download/?id=278

Congrats! I changed my OS and my hardware is detected, but only 1 monitor works at a time. I can swap between the three on the Matrox TH2Go. The maximum resolution is not close to what you get. Let me get you a screen shot.

Also, Everytime it asks me to restart because my GXm resolutions aren't supported.

Now when I restarted it. Things are back to square one.

So I connected my 19 ", Guess what even those don't work

This is surprising

But this was worse.

On opening the GXM setup , it requests me to extend the desktop onto all the screens and I click Yes. The result is I get a black screen with GXM written on it blinking thrice.

All very strange !

I think you should call Matrox ... http://www.matrox.com/graphics/en/support/contact/

Quote from iRacing forum

I spoke to Matrox (where I quickly got to someone very knowledgeable. Amazing in this day and age and a real positive for Matrox. We should all support mfgr's who provide great service!)

I have learned that many of the larger monitors lack "scalier" circuitry which adjusts the signal for different resolutions. The monitor manufacturers assumes the graphics card (or other device) is responsible for scaling. I am not certain why this is true (performance, cost?) but most smaller monitors tend to include this capability. The large monitors only run in native mode unless some other device is scaling down for them.

The problem is that the TH2Go doesn't do scaling on each of the 3 channels but assumes the monitors will scale appropriately. This is unfortunately not true with Samsung 305T monitors. The 305T native mode is 2560x1600, and the TH2Go is asking each monitor to run 1280x1024, but neither the TH2Go nor the 305T has the capability to scale the signal appropriately.

So a word to the wise if you are going to use a TH2Go to be certain your monitors have an on board scaling capability. Matrox is aware of the issue and may be able to provide a solution in the future.

Just something for you to think about, not sure if it applies to your Dells, but something to check.

Thanks for the heads up but I don't think that is the issue here ... Mach1.9pants uses the same Dell 2407 screen for his centre screen and 2 E2408 for the sidescreens ... all is working fine for him.

Yep the Dells are not the problem...they scale really well including the 30" from what I have read.

Can I use others cables instead of the ones provided by Matrox?

Yes ... so long as the cable from the computer to the TH2G unit is dual-link DVI ...
The 3 cables from the TH2G to the three monitors can be single-link.

Thank you very much guys. I seem to have finally cracked it. Looks like my cable was faulty :D . If I haev any further problems, Ill be back for your guidance.

Thanks a ton.

Yippie ... :w00t ... we have ... :surroundsmiley ... :triplewide

Pop by from time to time ... you don't have to have a problem to be welcome ... 8)

Hehe... good job Paddy!!!!! You da man!!!!!

Do you guys know if I can make 30" work??? :roll:

Do you guys know if I can make 30" work???

I´m also interested in that (hybrid th2go + softth). If supported and playable (older games), I´ll use native resolution 3x2560x1680. If game is not supported/not playable, then th2go with 3x1680x1050@57Hz. I think switching between both could be done in the fly, thanks to the many inputs of the 3008wfp. Am I wrong?

Can you test 1680x1050@57Hz with the Dell 30"?

It´s not in the official resolutions list, but should work because the upscaler, but I need to be sure.




Thanks
