Sharp unveils world's first THX-certified, 70in 4K HDTV

Sharp has followed up its reveal of ultra high-definition HDTV models at CES with the announcement of the world's first THX-certified 4K HDTV.

The upcoming Aquos LC-70UD1U is a 70in, LED-backlit HDTV with 4K resolution and THX's 4K HDTV certification, and will hit shops in August.

THX certification is the process of a third party, THX, evaluating the fidelity of an audio or video product and determining whether it reaches a certain level of standards. THX has been certifying HDTVs since 2006, but has only just begun certifying 4K HDTVs, with the LC-70UD1U the first model certified and planned to reach the market.

The LC-70UD1U has 4K (3,840 x 2,160) resolution, built-in Wi-Fi with LG's Smart Central apps library, a Flash-enabled web browser, and support for Sharp's Remote Control and Beam apps to control and stream media through your smartphone or tablet.

The HDTV's design includes a metallic black bezel, an open base that reduces the screen's physical footprint, and a new speaker system. The LC-70UD1U uses Sharp's DuoBass technology, building two subwoofers into the screen along with forward-facing midrange drivers and tweeters along the bottom edge of the screen.

The Sharp LC-70UD1U will be available in mid-August, and will have a suggested retail price of $7,999.99 (£5,260), putting it in line with other 4K HDTVs of similar sizes from major manufacturers.

However, there is still no consumer-available media for 4K content, so 4K HDTV owners will have to settle for upscaling for most of what they watch.
