We are trying to hook our TV up to our computer to use it as a monitor. What cords do we need to do this besides the normal monitor cord?

If you want audio as well, it will depend on what kind of audio connection your tv has next to the VGA (computer monitor) connection. If it looks like the normal RCA audio, (red and white plugs) you will need to get a male headphone jack (to plug into your computer headphone or speaker out jack) to stereo RCA cable so you would have a headphone jack on one side of the cable and a red and white plug on the other side. Now if your TV just has what look like a headphone jack next to the VGA (computer monitor plug) you will need to buy a male to male stereo headphone jack cable. for both of these, just make sure the cable you get it long enough, or buy an extension.
