THX, the company behind Lucasfilm's audio/visual reproduction standard for movie theaters, A/V equipment, and more, has released a new iPhone app to assist consumers with calibrating their HDTV's and home theater setups. The app is currently free for one week, but will rise to $1.99 after.

Thx
THX prefers that users connect the app to their television via Apple's official HDMI adapter, but AirPlay Mirroring can also be used for the visual tests -- audio tests won't work over the AirPlay protocol.

But those that do try out THX's method will be rewarded with modest improvements. In our tests, it worked as advertised. Speaking to The Verge, company reps made clear that Tune-Up isn't meant to be a substitute for having a professional visit your home for a thorough calibration. Instead, it's a tool that can (fairly quickly) help your new TV look better than it did the first time you turned it on. And as an added bonus, you'll be able to play the famous "deep note" that moviegoers hear before THX-certified movies in lossless audio.

THX tune-up is a free download on the App Store for 1 week, before rising to $1.99. [Direct Link]

It's a gimmick and marketing ploy.

If done properly it is in no way a gimmick or marketing ploy. It makes a HUGE difference in the viewing experience. Night and day on most TVs if done properly.

Umm you are totally incorrect, having your tv and sound system pro calibrated is like buying a brand new system afterwards, definitely not a marketing ploy!

Not really. You don't need to have a professional do it, but having your system (both video and audio) will dramatically change the experience.

I got bored and kept playing THX Deep Note through my 5.1 up loud. Slightly turned on right now.

Very cool. Though the 49 dollars apple wants for the cable, not so much.
