Make sure that you have set the Apple TV to “Mirroring”. THX tune-up uses both your mobile device screen and your HDTV screen, making this an interactive 2nd screen application.
The setting for mirroring can be found by double clicking the home button on your iPhone/iPad. Then scroll to the far left and you will see the
icon. You can then select AirPlay, Apple TV, with Mirroring set to “ON.” The set up screen should look something like this:

THX tune-up does not work with the iPhone 4 and Apple TV. You must have a Digital AV Adapter and connect via HDMI with your iPhone 4 in order to see the images on your television.
The following set up will give the best results when using your Apple TV:
Use an HDMI cable to connect your Apple TV to your AVR or HDTV
Settings -> Audio & Video:
Select: Dolby Digital: On
Select: AirPlay Overscan: Off
Connect via AirPlay to your AppleTV
Turn “Mirroring” ON
THX tune-up is a 2 screen application. The Get Started movie is played by the Apple movie player, but you will note when you are connected to the TV, the movie only plays on the TV, you cannot see it on the iPhone or iPad screen.
In order to have the 2 screens simultaneously working for THX tune-up, you must turn Mirroring ON when you connect to Apple TV via AirPlay. Please note, the mobile screen contains user controls for interactivity. On the television only content needed to make the adjustment is displayed, and you control the app from the mobile device.
For 5.1 speaker assignment and phase adjustments you must do all of the following:
Try the following:
The new AV adapter model number is A1422 versus A1388 for the 1st gen. The new part number is MD098ZM/A (MC953ZM/A is the old part number).
Use at least a 2 meter (6 feet) cable. Depending on the location of your AVR/HDTV and your optimal/preferred viewing location, you may find that a 3-8 meter (10′-25′) cable may be needed.
Set your AVR to Direct mode (or “Digital Auto Detect” or equivalent) as this will allow the AVR to process the Dolby Digital (AC3) audio which is used for the 5.1 playback when using a HDMI connection.

It will vary, but you should allow 10-30 minutes. You can stop at any time and come back later. Also, because the app is very interactive, you can perform the all of the adjustments or just the adjustments and features that you want without having to complete the entire experience in one use.

This is usually caused by your Local Area Network (LAN) setup. Apple has an article on how to troubleshoot this issue at http://support.apple.com/kb/TS4215. Note: You will have the best quality audio and video playback by using an HDMI connection.
We acknowledge that this can be tricky. You may find that doing any or all of the following will help.
The app will attempt to re-sync, but you may need to close the application and reopen.
Make sure that you have set the Apple TV to “Mirroring” to “ON.” See Q4.
Your AVR and/or speakers may not be properly configured or connected. For example, if your AVR is set to 5.1 or 7.1 speakers but you only have a 2 speakers (and maybe a subwoofer) connected. Go to the speaker setup menus of your AVR and set the speakers to match your actual configuration.
Please hold the camera as still as possible when pointing it at the television, wait for it to be displayed on your mobile device, and then make the adjustment. The camera refresh rate is dependent on the speed of your iOS device. This refresh rate is as slow as 1-2 updates per second.
When using a device with iOS 6.0.1 or 6.1, place your iPhone or iPad in landscape to display the video full screen on the TV. for the best display on the TV or Projector when using iOS 6.0.1 or 6.1. When using a device with iOS 5.1.1, the displayed video will always play in full screen, regardless of device orientation (portrait or landscape).
While you can connect to your television via VGA or Component, the video will not be full screen, and the picture quality won’t be the best. For the best performance from your mobile device, connect your device directly to your AVR/HDTV via HDMI with a Digital AV adapter.
Ensure that you are connected directly from your device with a HDMI cable to your AVR. If you’ve reported in the Equipment screen that you have HDMI and a 5.1 speaker setup, and are connected via some other means such as AirPlay with AppleTV or an analog connection, no audio will be heard.
This capability may be available in a future release.
