Sony Debuts 84-inch 4K TV At IFA
4K resolution requires a new video processing engine.
August 29, 2012 by Grant Clauser

LG isn’t alone now in their plans for a massive 4K TV. One of Sony’s big announcements at the Berlin electronics show IFA is an 84-inch LED-based 4K resolution TV.

It’s no real surprise that Sony should come out with a big 4Ker. Last year at the CEDIA Expo the company showed the first consumer home theater 4K projector. This 3840 x 2160 model (number XBR-84X900) will likely also be in the US at next week’s CEDIA Expo in Indianapolis, so we’ll give you an in-person impression report then.

The TV will use a proprietary upscaling technology called 4K X-Reality PRO picture engine to bring lower resolution content up to the level of the TV.

The 84X900 incorporates a 10 Unit Live Speaker system to create virtual 5.1 surround sound. You can take the side speakers off if you’re using a separate home theater audio system to provide the sound (and we hope you do).

Of course it’s a 3D TV and comes with passive, polarized glasses.

Smart TV features are expected in any new TV, and this model has full network connectivity with built-in Wi-Fi, access to the Sony Entertainment Network suite of services, plus Netflix, Pandora and more than 50 other streaming apps.

The TV can be operated by smartphone and tablet apps.

Sony expects to offer it for sale here this year, but has not released a price. Earlier this year Sony released a 4K upscaling Blu-ray player.
