Touch designer not working when TH2GO DP connected

Indeed, I was able to turn off the third output somewhere in the Matrox Power desk!

That's great news. I wasn't sure if you could use only two monitors with a triplehead. Did you end up figuring out the other issues?

Quadro cards will only output a maximum resolution of 2560 by 1600 out of a single port

hey keith, are you sure that this is the maximum? I know this is what nvidia puts in their datasheets, but i think people have been using dual/tripleheads with 2xHD on each output for years.

I'm looking into using 2 quadro 6000 in sli mosaic, and split each output (using a triplehead2go DP edition) into two HD signals for a total of 8 outputs from a single system

Can anyone confirm that this will work?

You're correct Achim. The 2560 by 1600 limit is simply the wording of the marketing dept at Nvidia. In reality a DVI-D output is limited by it's 300Mhz clock. 2560x1600x60hz = 245,760,000. So even there is some room to grow. Assuming you have a device that can read it, any width/height/fps combo can be used (up to the max texture width/height supported by the card). You can get higher resolutions if you reduce the refresh rate of the output. I've done 7680x1080x30hz before.
I haven't tried but I wouldn't be surprised if DisplayPort outputs could do even more since they have a higher possible pixel clock.
So it's not limited by the card, simply the specification of the cables you are using.
Remember if you are going from a DisplayPort output to DVI at higher than 150mhz (DualLink DVI) via a dongle you need to use an Active DisplayPort converter with a USB power:

that's great news,I thought that seemed a little low.

Achim, I just quickly tested my two dual heads on a 5000. 3840 by 1200 came up as a default res as well 3360by1080. I was able to choose 3840 by 1200 on both outputs of the card and able to make a mosiac desktop at 7680 by 1200 (with only one actual 1920 by 1080 monitor hooked up to 1 of the dualheads). I quickly tried to make a 3840 by 1080 custom res for the dualheads but it didn't work. I only set resolution settings no timing also I don't have the matrox drivers installed so I couldn't choose any matrox settings. I imagine it could be done with a little more effort. If someone knows some timing settings I could them a try.

Keith I think I am sorted, thanks. At least I've reached a point where I'm not configuring the T-head anymore. So I guess no news is good news.
