Hi
I’m wondering if the fancy Nvidia Tesla boxes work with Touch? Apparently they can leverage 4 cards and appear as only 1 to the host computer with the SLI mosaic mode
(nvidia.com/page/quadroplex.html)
otherwise does anyone have any experience/ideas on how to output across a ridiculous number of flat panels? (We are thinking of a wall of flat panel screens 12 + )
cheers

Hi doom
Get an nvidia i790 board this should give you three pci-express16X slots
then get three Geforce GTX 280s for gpu power, the ati HD4870 1GB might also be able provide enough, but haven’t used ati cards extensively so… Then get 6X matrox TrippleHead2Go digital(that is with DVI connectors)
and theoretically you could go up to 18 monitors at 1280X1024.
There also mainboards like the msi P6N Diamond that have 4Xpci-express, two 16X, two 8X all of them can accomodate 16X cards-actually I have tested this one with four nvidias gf 7950gt and works fine. So combine it with TrippleHeads and you go up to 24 mons 
Sounds ecstatic.
However, from what I’ve read at the wiki I dont think Touch can handle it, multi-monitor support has a bit of development ahead of it in my opinion.
There is other software that can you get there.
Good Luck
P.S. The Tesla boxes that you mention do not have actual outputs they transfer the data back to the main memory and then to an actual framebuffer. The most you can get from a quadro is 8 dual-link DVIs with the Plex 2100 D4 which then you can SLi it with a second one and go up to 16 DVIs. Also nvidia mentions a feature on their high end drivers that they call SLImosaic which supposedly unifies the connected physical cards to single logical one so the OS and apps see virtually a single framebuffer. That is also the safest and simplest way to overlay video( either played back or from camera feeds) in multiple monitors from the hardware side of things. Otherwise you need some elaborate patching-programming to do it.
In the case of quadruple graphics cards keep in mind that in most cases as in the case of the MSI mainboard you will have to opt for single slot graphics cards.
And the full blown smily is there by hastiness.
I prefer the simpler more minimal approach
Although we haven’t tested Touch with SLI, it works great with Matrox Dualhead2Go and Triplehead2Go adaptors. You could get 6 outputs using a TripleHead2Go with a single card that has dual outputs.
cheers thanks guys
i have used the dual and tripleheads extensively and they are great - might have to use them
however start running into problems with running out of video memory - as each screen is 1024 x 768 or so, its effectively a 6 megapixel image, 50 times a second, and any TOP operations start spanking me quite quickly
I was thinking, with a mega huge scene like this, is there anyway to cleverly synchronise across several machines in effect so that i have have 4 cameras in the scene set up and then 4 computers each rendering a camera?
so all the computation and whatnot happens on the central machine, but the rendering and output happens on the others?

Hi,
I’m going to be doing a project using a Mac Pro(running win7 64bit bootcamp) and I would like to run 4 video outputs (3 projectors and a monitor). Would it be possible to achieve this with 2 graphics cards? if so, which graphics cards would you recomend. I’m trying to avoid using a triplehead at this stage.
Cheers,
Adam
If you are using more than one graphics card you pretty much must use Quadros with GPU affinity (look in the wiki for more information). Otherwise the driver will do a very poor job of keeping all the drawing commands and data segregated between the GPUs.
Thanks Malcolm
I’m thinking of buying two of these
nVidia Quadro PCIE FX 580 512MB GDDR3 128-bit
do you think it might worK?
cheers,
Adam
