You're going to want a VGA, Component (red green blue), or HDMI imput on the monitor for the xbox 360 HDMI of course only if your have an Xbox that has that. And I dont know if they make DVI ones, but you can get a VGA converter. I have mine hooked up to my monitor via component, then i have my computer hooked up through DVI. Here's my monitor... but I don't think you wanna blow the cash on it :P http://accessories.us.dell.com/sna/prod ... u=320-6272 I dont know if your going to get a 17-20'' monitor thats quality and has the inputs needed. I'd suggest getting a LCD tv with all the hookups. especially since you wanna hang it on the wall, a lot of monitors are thrown out the window in terms of choice since many dont have removable backs. And you dont want composite, thats old technology. VGA and Component are my suggestions
