Title pretty much says it all.

I just want to play my xbox and use my iMac 21.5" as the 'Tv'.

Cheers for any help.
 
Get one of the TV tuners (people like Elgato) and use the video in feature. Unfortunately, this method has lag :(
 
The elgato one last time I checked doesn't do any sort of HD, though it might have changed, I believe the software however has a gaming mode that actually has minimal lag that isn't noticeable.
