    • The table below is to guide you.
    • Please check the HDMI specs for your Android device to ensure you get the correct adapter.

    * Most MHL adapters require power to operate.

    Below are some sample adapters.

    8. My HDMI adapter does not work with my Android. What is the problem?

    • Check the specs for your Android device to confirm the type of HDMI adapter needed.
    • MHL and Slimport look the same because they both connect to the micro USB port. But they are not the same; please ensure you are using the correct adapter for your Android.
    • MHL adapters must be connected to a power outlet.
    • HDMI adapters are available from many manufacturers; some are more reliable and perform better than others.
    • Make sure you can see the Android screen on your TV before you launch THX tune-up.

    9. Why can’t I see my Android screen on my TV or projector? I am connected by HDMI.

    • Check and confirm you have selected the correct inputs on the TV and AVR.
    • Check all cables to make sure they are working and they are firmly connected.
    • Verify you have the correct HDMI adapter and it is securely connected to your Android.
    • If your HDMI adapter has a port to connect power, plug it in. It may not work without power.
    • If you have checked all of the above and you still cannot see your Android screen on your TV or projector, you may need to get another HDMI adapter.
    • HDMI adapters are available from many manufacturers and their performance and reliability can vary.

    10. Why isn’t wireless Miracast connection supported by THX tune-up?

    • THX tune-up does not control Miracast performance or set up, it simply uses the wireless connection to display the app content on the television.
    • After extensive testing on multiple Miracast devices from multiple manufacturers, we found that connection reliability and stability was not consistent. Therefore, we have decided to not recommend Miracast for connection with THX tune-up at this time.
    • We will continue to monitor Miracast technology and may choose to support it in the future.

    11. Can I still try to use my Miracast device with THX tune-up even though THX does not support it?

    • Yes. If you already have a Miracast device and it works reliably, you can try it with THX tune-up.
    • There is nothing in the app that prevents you from using it to connect your Android to your TV or projector.
    • This is true, even though you can only select HDMI from under Mobile Connection in the Equipment Selection section of the app.
    • Follow the connections instructions for your Android and Miracast devices to wirelessly connect them.
    • If you try Miracast, you should use it connected to the TV or projector, not the AVR. Why?
      • Miracast devices do not support 5.1 surround sound and will mix down the 5.1 audio to 2-channel stereo.
      • Some Miracast devices will not establish and/or maintain connection with AVRs.

    12. I used to see short messages displayed for a few seconds on my screen that gave me info about what the app was doing. I don’t see them anymore, how do I get them back?

    • Android refers to these messages as “toasts.” In order to see toasts you must have Notifications set to ON in the THX tune-up App settings.
    • Go to Settings -> Apps -> THX tune-up -> Turn ON Show Notifications

    13. How do I turn ON the overlay screens which describe the function of each area in the app?

    • The first time you use the app the tutorial overlays screens will appear to describe the function of each button.
    • Tutorial overlays are set to appear only once so they do not get in your way once you are familiar with the app.
    • To reset the overlays, go to app Home Screen -> Info Button.
    • On the Welcome Screen press the link in the lower right that says “Reset Tutorial Overlays.”

    14. I cannot hear Deep Note in 5.1 surround sound, why not?

    • In order to hear 5.1 coming from the app, some AVRs need to be set to a particular mode. This mode is often referred as “Direct Mode” or “Digital Audio Detect Mode” or equivalent. Refer to the manual for the AVR.
    • Make sure the volume level on your Android device is turned all the way up.
    • Your Android device may not support 5.1 or true 5.1 surround sound.
      • For instance, the Samsung Galaxy S4 supports “virtual surround sound” and you will not hear Deep Note in 5.1 from the surround L/R speakers. Instead the device’s virtual surround sound feature will mix 5.1 audio to the front speakers only.

    15. Why do I not hear sound coming from THX tune-up?

    • Check the volume level on the Android device and the TV or AVR. If volume is low, you may not be able to hear sound.
    • If your device is connected to an AVR, make sure your AVR is set to Direct Mode or similar mode.
    • If you are using a Samsung Note 3, you must turn up the Media volume level.
      • To turn up the Media volume level on the Note 3, press the volume level on the device.
      • You will see the Phone volume control.
      • Press the gear icon to the right of the volume control slider.
      • This will bring up the expanding volume control interface.
      • Turn the Media volume control slider up.

16. What is the best length HDMI cable to use?

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.

17. Why does my device screen sometimes rotate when I’m moving though different levels in the app? From normal to upside-down and then back?

  • You may need to set Auto-rotate on your Android device.
  • Go to Settings -> Display -> Auto-rotate and set Auto-rotate to ON.

18. How should I set up the Audio Video Receiver (AVR) for THX tune-up?

  • Set your AVR to Direct mode or Digital Auto Detect mode or equivalent.
  • If your AVR does not have such a mode, you may not get accurate results from the sound tests in the app.

19. Why are the 5.1 Speaker Assignment and Speaker Phase tests not working properly?

  • Confirm the AVR is set to “Direct” or “Digital Auto Detect” mode or equivalent.
    • If your AVR does not have this mode, it may not process the AAC 5.1 audio tones to provide accurate results with the sound tests in THX tune-up.
  • Check the specs on the Android device.
    • Some Android devices implement a feature called “virtual surround sound” and will mix and play audio on multiple speakers even though audio is present on only one channel.

A brief explanation about “virtual surround sound”:

  • The 5.1 sound test signals in THX tune-up use all 6 channels and, depending on the particular test, certain channels do not contain an audio signal.
  • For example, when running the Front Left Speaker Assignment test, audio is present only on the Front Left channel of the 5.1 signal.
    • If your speakers are connected correctly AND your Android is processing true 5.1 surround sound, you should hear sound coming from the Front Left speaker only.
    • The other speakers Center, Right, Surround Left, Surround Right and Subwoofer should be silent because these channels do not contain audio.
  • However, some Android devices “virtualize” the 5.1 surround sound; mixing the audio on one or more channels and distributing sound to multiple speakers – even though there is no audio on these channels.
  • If your device utilizes “virtual surround sound” it will not process the individual channels used in the Speaker Assignment and Speaker Phase 5.1 surround sound tests, and the tests will not be accurate.
  • We have observed this behavior with the Samsung Galaxy S4 and HTC One.
  • This is not a problem with the app; it is a function of the Android device and how it processes 5.1 surround sound.

20. Can I use Chromecast with THX tune-up?

  • No, Chromecast cannot be used with THX tune-up for Android at this time.
  • Until Google’s announcement on February 3, 2014, the Google Cast SDK which is used for Chromecast was not available for developers to use in published apps.
  • THX used and tested Chromecast while developing THX tune-up for Android and we decided to release the app for HDMI hard-wired connection. THX acknowledges it is cumbersome to connect your Android mobile device to your TV or AVR with an adapter and HDMI cable. However, our tests indicate it is the most consistent and reliable method for allowing the 2-screen interactive experience needed for users to adjust picture and sound settings on home theater equipment.
  • Now that the Google Cast SDK is available for developers to use in published apps, THX will investigate future implementation in THX tune-up for Android.

21. Can I use THX tune-up on a “rooted” Android device?

While THX tune-up may work on a “rooted” device, we cannot guarantee THX tune-up performance on a “rooted” device.

22. The app is crashing whenever I use the camera filter for the color and tint adjustments. How can I stop this?

  • Make sure that there are no other apps running on your Android device that are using the camera or the camera service.
  • Power off and off the Android device. Launch THX tune-up and go immediately to the color or tint adjustments and activate the camera filter.
  • After doing above, if the camera filter continues to crash, you can help us correct this by emailing THX at tuneupsupport@thx.com.
  • In your email, please tell us if the crash occurs if you are not connected to a TV or AVR. Please provide the brand and model of your Android device and the Android OS version.
