Using the 21.5inch iMac for Video input (eg Xbox 360)

[nacintosh]

I know about the 27 inch and how it can is can use its mini display port as a video input. But I was wondering if you could use the 21.5 inch to do the same. From what I am reading its seems though that it can't, is there a hack of some sort that could do this. This would be a great 1080p screen to use instead of buying a brand new TV. :)

Any answer would be great...

Thanks in Advance

The 21.5" doesn't support input, sorry :(
