Check out this video from Atlona that will show you how to connect you iPad or iPhone to your HDTV using Apple's VGA adapter and Atlona's AT-HDVieW VGA to HDMI converter. The AT-HDVieW, which is a plug and play device, will automatically sense the native resolution of the display and scale the device's output to match it. The converter will take audio signal from the device and embedded it into the HDMI signal output, so that user is able to enjoy both audio and video though one cable. The HDVieW is a scaler-converter, which means that it will always work without any adjustments to the video card software in addition to that the video quality will be dramatically increased due to the built-in high quality scaler. The Atlona converter is USB powered and therefore will not require additional power supplies.
