HDTV just died, so I am looking monitors, help!

I have a 360 and want to buy a monitor instead of an HDTV. What do I need to hook the picture and sound from my 360 to the monitor?

With the proper cable you should be able to run the xbox through the 2.1 set with no problems. Do they have an aux input or anything like that on the back or is it just the one input from the computer? An A/V receiver is a piece of equipment that takes numerous inputs from audio or video sources and outputs them to a single device.

Captain_Tripps: the majority of people don't have amps or receivers and just use their TV speakers through SCART, phono or HDMI etc.

Something like this might be in order if he wants to use the 2.1 set he has: http://www.amazon.co.uk/Phono-Female-3-5mm-Audio-Cable/dp/B000Q8KSS0

I bet more people than not with HDTVs do have receivers. You could probably also use your PC speakers directly with your xbox with the right adapter. (2 channel analog only though)
