THX tune-up is a new app from the folks behind modern-day cinematic sound, THX, which hopes to help you calibrate your HDTV to its best visual and aural settings. Connect your iPhone 4 or iPad 2 and up to your TV with an HDMI cable or AppleTV/AirPlay and point the camera at your screen to have THX tune-up help you get the best of each.

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 4 (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.
