My three screens are all connected via HDMI. And they’re all standard “full HD” (1920x1080.) In other words, nothing fancy. If they weren’t monitors but TV screens, it would be exactly the same. Unlike with ATI cards, nVidia Surround technology does NOT necessarily need display ports. In fact the three screens can all be attached to HDMI ports. BTW, the resolution is 5760x1080 @ 60 Hz. My GPU is the amazing GTX780ti. Definitely pricey ($700 street), but well worth it. Oh, and this monster is also incredibly quiet. If you have a good computer case with great noise reduction (like the Antec Sonata III), you don’t even hear it until you put your ear to the case.
