The iMac has an amazing screen measuring up to 27 inches on the latest model. A new adapter has been created by Belkin that lets you use the iMac display for your Xbox 360 or PS3.
The adapter is called the Belkin AV360 and features HDMI on one side for input and miniDisplayPort on the other side for output to the iMac display. The box in-between takes care of converting signals where necessary.
To get the AV360 converter working, you need to have a spare USB port to provide power to it, or an external USB power source. Once the console, display adapter and iMac display are connected together you can go ahead and play games on your iMac screen.
The adapter does have it's downsides though in that it does accept full HD at 1080p but can only output at 720p. The other downside is that it costs a hefty $150 which is silly money really unless an iMac screen is your only option for some reason.
