Hi, I have a Dell computer with a trinitron 19" monitor and a Westinghouse 19" LCD-TV that I would like to hook up so I can use the TV as a second monitor.The tower is a Dell 8100 Dimension with an S-Video port and a 15 pin VGA port.Graphics card is a NVIDIA GeFORCE2 MX/MX 400. The TV has an S-Video, D-Sub, and a DVI-D port. The trinitron has only the VGA port. I have already hooked them up with the S-video cable but the best resolution I can get is 640 x 350 @70hz. The manual says the tv is capable of 1440 x 900. Will I be able to hook up the two through the VGA port on the computer? Which ports should I use on the TV other than S-Video? What cables/adapters will I need? Will the sound still come through if I use the source D-sub or DVI-D port? Thanks

The VGA port will only drive 1 monitor at a time. Theoretically, you could possibly create a split VGA cable and hook up 2 of the exact kind of monitor, but what would be the point? They would both display the exact same thing, there would be no usable increase in "desktop" space. You would have to connect to a HDMI, DVI, or RGB(VGA) input port on the TV to achieve a 1440x900 resolution, none of the other inputs on the TV have that high of resolution. You need a video adapter in your computer which has the correct output capabilities and then a matching cable. There isn't any adapter which can take a S-video output and turn it into a 1440x900 resolution. Don't know anything about the sound capabilities of a D-sub or DVI-D port.

Thanks Pyrolitic, Looks like I need a new graphics card with two VGA ports, or one vga and one dvi port. What specs do I need to look at to match with my computer? Any suggestions?
