iOS: Adjusting the settings on your HDTV and sound system make for a better entertainment experience compared to just using the default out-of-box settings. While we've posted guides on getting more out of your home theatre and calibrating your HDTV, this interactive app from THX makes it even easier.
To use THX tune-up, connect your iPad or iPhone to your TV or sound system, either wirelessly via Apple TV or with an Apple Digital AV adaptor and HDMI cable. Then select the type of equipment you have.
The app offers tools and narrated instructions for adjusting aspect ratio, brightness, contrast, colour and tint. You can test your sound system's setup to make sure your speakers are connected to the right output and that they're in phase (which means it's easy to tell where the sound is coming from).
DVDs with the THX logo already have a calibration tool on them, but using your iPad or iPhone has a unique benefit: THX tune-up uses your device's camera to set colour and tint, so you can point your device at the TV to see if it's adjusted correctly -- no need for special filter glasses.
The app is free until February 4, and an Android version is due to be released in coming months.
