Dual Monitor Set Up

Hey guys, This is my first time on this forum and i was just trying it out, i was looking for some help and i thought that a computer help forum would do the trick, i have a win 7 64 bit desktop computer the model is gateway SX2802 with a bunch of ports. I have 9 usb ports a 1394 port a hdmi port a esata port and 9 usb ports a vga port and a spdif. I'm looking for an inexpensive way to get a dual monitor setup. i have a flat screen tv that fits perfectly on my desk that i use for my xbox my wii and my xbox 360. i could also use it as a dual monitor until i get another monitor if thats possible. I need help finding what converters/ cables and things to buy and use. i also have 2 old laptops that i would be willing to use as well. a compaq presario c700 and a presario v6000. if someone could help with this that would be fantastic

 

What inputs are there on the TV Lax?

 

s video and the yellow white red and the antena thing used for cable
and the colors for hd plug in play thing

 

I'm Guessing by the sounds of it, that its the Old CRT type and not the LCD/Plasma type

If its CRT I would think your going to need a card,

if its LCD you should be able to connect straight to it using HDMI,VGA, or DVi-I.
