Yes I have looked at that several times and tried using multiple configuartions with dual and single vid cards. I ordered a few
adapters and they worked well. Having 4x 1080p monitors plugged in I was able to get 2x2 surround working.
Now for pulling off the final hurdle of 2x2 with Samsung's curved TVs which are all 4k now. Before you scream about not being able to run a full 8k display (I wouldnt expect any computer to handle gaming at 8k yet) I only want a 4k total display across 3 TVs (1080 each). Problem is Nvidia wants to jump straight to something past 8k total.
All TVs plugged in, 4k comes up on all displays (so many pixels!). I put them in the correct tiled layout and drop the resolution to 1080p per display. All looks great! Now I just need this in surround with bezel corrections so I can fullscreen.
So same gig, go to surround mode, 2x2 topology, 30 hz.... no resolution options. Only 8192x4320? I thought 4x was 7680 x 4320... where did we get an extra 512 pixels? Attempting to enable it just gives me no signal error on TVs. Latest drivers (352.86) were installed today on a fresh install of windows 7 64. I need to be able to get to regular 8k and drop the resolution or enable surround with going straight to 1080 per display.
I belive I may be at the limits of the 780 cards and have ordered a 980. Hopefully we'll see if that helps in a few days.
