I have a 20" aluminum iMac running OS X 10.5(leopard) and would like to add an additional display to it. But what i want to do mainly is use the additional monitor for use with my Xbox 360 (my tv is way to small to use for xbox) - Is it possible? How would i connect the two? Also, once i get it all hooked up, how would it appear on the monitor? (meaning like would the graphics from the xbox be in like a window or something?) Assume i dont know anything as far as adding an additional display goes. i would think it would be possible, but dont know how to do it. Thanks for your help!
