About THX®


Founded in 1983 by legendary director George Lucas, THX was born out of the desire to improve cinema video and audio capabilities. Lucas wanted to make certain that when his latest movie played in theaters, all sound and image nuances would be properly reproduced to completely envelop the moviegoer and change the way they experience films – “as the artist intended.” His team developed a performance standard which became known to the world as THX. The company was officially introduced to the public with the premiere of Star Wars: Episode VI – Return of the Jedi.

Since then, THX has taken this knowledge and translated it to other entertainment devices, creating a set of rigorous technical standards that allow the consumer to experience the true impact of every sound and image as it was envisioned in the cinema – within the living room, dedicated home theater, in the car or on the go.

Over the past 30 years, THX has certified thousands of movie theaters, post-production facilities, sound mixing rooms, consumer electronic devices, DVD/Blu-ray titles and games. It is this level of involvement within the content community and commitment to genuine reproduction that makes THX an expert in translating artistic intent to audiences worldwide.

THX Certification is an assurance to consumers of uncompromised quality, best-in-class performance and consistency. Blending art, technology and the ever-changing challenges of a real-world viewing environment, THX and its partners continue to deliver a transcending experience just as the creator intended.

THX Certified home audio and video products are engineered to be best in-class and designed from the ground-up to deliver the true impact of movies, video games and music.

How THX Certification Works

From early design concepts to product rollout, THX works with its manufacturing partners at each step of product development. Every detail is meticulously mapped to the THX performance standards. And THX engineers spend countless hours testing and analyzing each product for performance, usability and interoperability.

THX Certified Projectors and Displays

In the studio, every shadow, color and detail is carefully adjusted to deliver the right mood and impact. Only THX Certified plasmas, LCDs and projectors, featuring THX Movie Mode, let you recreate this experience at home with the push of a button.



What does it mean to be THX Certified?

It means each TV and projector has gone through a rigorous design and laboratory testing process, which includes more than 400 data points to ensure exceptional image quality and signal processing performance in your home theater.

What are the Key Benefits of THX Certification?

  • Exclusive THX Movie Mode: Comes as close as possible to reproducing the HD Color Standard used by filmmakers in the studio with THX Movie Mode.
  • THX Bright Room viewing mode: Included in all THX Certified displays and projectors, this viewing mode was pre-calibrated by THX engineers to optimize picture quality and maintain accuracy to the original content in viewing environments with high ambient light.
  • Smooth motion for every type of content: THX certification improves de-interlacing and scaling performance, ensuring smooth motion for action-oriented content.
  • Optimized video scaling: Presents all content in the best resolution possible, including standard definition video.

Color, Black Levels and Beyond in Your Home Theater

Sports fans and home theater junkies often complain of jaggy lines and image softening when a TV’s motion becomes too intense. THX works closely with manufacturers to minimize these types of distracting artifacts, letting you experience clean, smooth motion and vivid colors with every frame.

THX Certified Speakers

A Mighty Subwoofer

Movies, music and games are featuring more deep bass elements than ever before. To accurately recreate the roar of the jet engine or the sound of a freeway bridge collapsing, THX certification requires bass from all channels, including LFE, be redirected to the subwoofer. For this reason, THX Certified Subwoofers must extend to 20Hz (-6dB) to handle all bass levels with ease.

In-Wall and In-Ceiling Speakers

THX Certified In-wall and In-ceiling speakers deliver the appropriate frequency response and high output and imaging quality of a traditional box speaker. This provides the best of both worlds—THX surround sound performance from components that blend harmoniously with any room decor.
