NVIDIA's revealed more details on 3D Vision Surround on their
nTersect Blog. As I reported earlier, 3D Vision Surround offers 3D Vision support spanned across 3 displays, effectively allowing you to run three 3D displays simultaneously. NVIDIA says you can also use Surround in 2D mode also. In addition to supporting GF100 Fermi, NVIDIA also confirmed that existing GT200 cards will also support 3D Vision Surround.
I'll be interesting to see how they integrate the tech into GT200 cards though, considering boards only ship with 2 DVI outputs.
