Hi List,
what's the best hardware approach to render 12 screens with Gem? A computer with a quad head GFX card and four triple head2go? or better for synced computers? The screens display multiple movies at the same time which change their positions and the bezels of the screen shall be subtracted from the image (gemframebuffer)...
Anyone has done that before?

What size display?
Some commercial LCD and Plasma screens have built-in video wall capabilities so you can use a VGA DA to mult the signal to a bunch of screens and then have the display carve it up. This also allows working at lower resolutions for better performance. A dozen 1920x1080 screens is a lot of pixels!

we've been using up to 8 projectors, using 3 triplehead2gos the main problem we had was, that our gfx-card was only able to render max.textures of 8192x8192, which means, you cannot create a gemwindow that is bigger than that. (note that both width and height are absolute boundaries, so you cannot use a 10000x1000 window with the above setting).
another option would be to use chromium [1], to distribute the output rendering to serveral client machines, but i never tried this in a real-world application (and afair, you might not be able to use modern things like shaders)
