THX tune-up features custom video test patterns, carefully selected photos and tutorials to help you adjust and confirm the best picture settings on your display based on your room lighting. Using special test sounds, THX tune-up also lets you check your external speakers to make sure they are working in phase and are connected properly for 2-channel stereo or 5.1 surround sound systems.
THX tune-up is completely interactive and you will be able to go through it at your own pace and in any order. Use your iPad 2 (or later) or iPhone 4S (or later) to connect to your display or sound system with an AppleTM Digital AV Adapter and HDMI cable or through a wireless Apple TV. NOTE: 5.1 audio tests are only supported with an HDMI connection.
To get started, locate the adjustment buttons on your television and audio video receiver (AVR) remote controls and then simply follow the THX app tutorials which will walk you through your “THX tune-up.” The app offers tips about your remote control, room lighting, viewing distance and other helpful advice.

THX tune-up uses your iPad or iPhone camera to set color and tint with a special built in color filter. Just point your device camera at the TV screen and see if your color or tint is adjusted correctly.
