Hmmm.... I've been doing some net searching on this. Nvidia has NO help at all on the subject, and I can't seem to find what I want to know. The pages I googled were all about TVs, games and DVDs. Basically, what do I need to do? Plug in the 2nd monitor and reboot, then shift screens around? The 6600GT has dual-monitor support, but I don't want to make some stupid blunder with a brand-new machine. mac
