Hello, in this pic:http://img142.imageshack.us/img142/4847/14150141062yr.jpg
for the 1st cable, the one on the very left i was wondering what it did. Would i be able to plug my xbox 360 into it and play my xbox on the monitor?
Your graphics card has to have vivo(video in, video out) capabilities. The guy posting above giving you advice is a n00b.
Most of the time, the s-video plug you see on graphics cards is for TV output, not for any type of input.
No vivo - no plugging in your console.
