First off, I want to say that these forums have been a fantastic source of information, and that I have personally benefited from every answered question that I have asked here in the past. My thanks goes out to those who help. To those who are unfamiliar, these two devices are peripheral hardware units that convert and correctly scale HDMI input to Apple's Mini Display Port. This allows devices such as Xbox's, Playstations, Blu-Ray players and other sources that put out an HDMI signal to be connected to iMac's, therefore, enabling Apple computers to be used as extended displays. http://www.kanexlive.com/products/kanexXD.html http://www.atlona.com/ATLONA-HDMI-MINI-DISPLAYPORT-TO-MINI-DISPLAYPORT-SCALER-AND-SWITCHER.html I am considering purchasing one of the two, however, I do not know what the difference is. They both advertise that they do the same thing, and reviews on each respective product are similar. Albeit, the Atlona unit looks a bit more intricate, but the two products may be identical "under the hood." Can anyone clarify the difference? Thanks a ton.
