George,
I am in the same situation as you were/are. I was wondering if you came up with a solution? In order to get the 2 monitor + NTSC output I currently use 2 540’s however I’m not too thrilled with the quaility of the NTSC signal and I can’t upgrade to Open GL 2.0. I was thinking of one of 2 solutions, either a 1700 and ditrching the 2 monitors for big one or a 1700 plus a black magic decklink card. Let me know how you solved your predicament.
Thanks
Mike Mohr
