I want to set up multiple monitors to one computer but in a bit of a strange way and I need some help. I currently have an Nvidia Geforce 9500GT with 2 DVI ports and an S-Video. I've got two LCD screens connected to the DVI ports and the S-Video is running to my DLP HDTV. For reasons beyond my understanding, the card will only let me run two monitors at once (so a work around is I've got a nifty AutoHotKey script that switches from the dual monitors to the TV and back).
What I want to do is get a third monitor and turn it vertical for web browsing and keep the other ones horizontal for gaming and movies. Also for obvious reasons, I'd like to connect my HDTV through DVI -> HDMI instead of S-Video. I'd like to be able to run all 4 displays at the same time (TV isn't too big of a concern, but the 3 monitors must absolutely work at the same time). So my question is how would I go about achieving this? My video card supports SLI but Nvidia doesn't do a great job explaining how to use it. Also at my work we have video cards in our computers with one DVI port but splitters going to two different monitors. The computer recognizes both as separate monitors. One guy adds a third to the motherboard's onboard video. Is that another option I can use for at home (even though it's VGA)?
