Hi All,
Firstly, I hope this is relevant to this thread as I was following it prior to getting my iMac and Atlona AT-DP200. This is my account of how to get the results I was hoping for
I was previously using a Benq V2400W @ 1920x1200 via hdmi which distorted vertically
I can confirm that the iMac 27" CAN be used as a screen for an XBOX 360 ( at 720p ) on an HDMI version of the Xbox 360 in FULL SCREEN ( no black surrounds as I had earlier feared )
I bit the bullet and today I received the Atlona DVI to Mini DisplayPort Converter ( AT-DP200 ) from MacFixIt.com.au AU$219

You also need the equivalent of BELKIN MDP TO MDP 1.5M CABLE from Apple

You also need to get from Male HDMI ( HDMI cable coming out of Xbox 360 ) to a DVI female so the Atlona converter can plug into it
I did this with a Male HDMI to female DVI connector $18

Now it took me a while to develop a working process, so here is the shorthand version.
Step 1. Set the resolution of your xbox 360 to 1280x720 before you disconnect your old screen / monitor ( REALLY IMPORTANT )
Step 2. Connect the Atlona Adaptor MDP adaptor to the 'frankencable' ( See pic )

Step 3. Connect USB cable from Atlona converter to a powered USB port ( front or back of xbox should be OK )
Step 4. Turn on Xbox using controller
Step 5. Wait until xbox has booted
Step 6. Connect Belkin MDP cable between iMac and Atlona adaptor
Step 7. Pray
I did not have to press Command - F2 for the Xbox screen to appear it took 10 seconds to register and it did flick once to an xbox image then back to black before stabalising
To get your iMac's screen back, either unplug the USB or the Belkin cable from either the iMac or the Atlona
To get the xbox displaying again you must disconnect the Belkin MDP cable then reconnect it. I could not get the xbox to re-display without doing this - ever.
The picture quality is pretty damn good and DVD's played well too.
I hope this is useful to some if not all
