From looking through the forums it appears that I would be able to hook an xbox up to my Betson monitor with the help of a X2VGA adapter.  
I know with my PC hooked up I need to be careful of running resolutions above 800X600.  Is there the same type of concern with an xbox or is it a different type of signal input?  Anything else I'd need to be concerned with this type of setup?
I was thinking of possibly using a switch that I would mount on the side of my arcade so I could easily flip between the xbox and the pc.  Anyone done anything like this and if so what type of switch box did you use?  Thanks.
