How to connect one pc to my tv and dual monitor with both computers?

Im trying to set up my computer to watch movies on my TV and dual monitor. I do not have an S-video hookup in the back of either computer, just the vga ports to hook up my monitor. I will only have one computer connected to the TV, but want to dual monitor with both computers.

One of the computers that I鈥檓 running is a HP pavilion a1540 and the graphics card is an Integrated Nvidia Geforce 6150n le, this would be my main computer. I do not wish to remove the graphics card, I do not wish to loose performance, but need a s-video output.

The other computer is a Gateway with a Geforce2 MX 100/200 graphics card.

From what I understand, I need a video card with a TV output , so I can connect a s-video cable from my computer to my TV. I would also need a graphics card that supports dual monitoring.

I only need a s-video port on the Hp computer, that鈥檚 the computer I will watch movies on. So, the question is can I purchase a cheap video card with a tv out port, just to hookup the s-video cable and keep the graphics card that I have? I need both graphics cards to match in each computer for them to dual monitor right?

You can use a VGA to video converter that has a s-video output. The VGA signal is passed through so you can still use your monitor at the same time. Its almost cheaper to get a new video card that has a s-video port on it. If you really don't want to do that, this is the way to go.
