3 monitors plus HDTV with SLI

Hey,

I'm thinking of getting a triple monitor setup using two nvidia 470s in SLI, but i would also like to run an additional 26" HDTV on the side to run Windows Media centre. Is this possible in an SLI setup where three monitors are in surround, while an addition LCD is not? If not, would an addition lower-end nvidia card that is powering the hdtv separately work?

Thanks!!

You can only drive up to three monitors in SLI, however you can drive 4 with it off and yes you could drive 4 with a card outside of the SLI array.

So if I had SLI on for the triple monitors with an additional card running the 4th, it is possible?

Correct.

Just to confirm what's already been said, here's Nvidia's page listing display options for surround view with an additional 4th display.
