LG unveils £14,000, 84in 4K HDTV

If you have around £14,000 spare, you'll be able to get what could be the world's largest 4K HDTV next month, when LG launches its 84in, ultra high-definition HDTV, according to the BBC.

The new screen is four times the resolution of a standard HDTV and is just 6in smaller (diagonally) than Sharp's "largest LED HDTV on the planet."

Currently, HDTVs display content at 1080p (1,920 by 1,080 pixels), or slightly lower 1080i or 720p resolution. 4K video is the next step in high definition, with a resolution of approximately 4,000 by 2,000 to 4,000 by 3,000, quadrupling or sextupling the number of pixels in the picture. It's currently a very early technology, used mostly in professional settings like cinemas and with almost no commercially available displays or media. It's the high definition we'll be using in five or 10 years time, when the £13,940 price tag we have here will, hopefully, no longer be the standard.

4K displays have seen a few products users can conceivably buy, but they're exorbitantly expensive. Last year, Sony launched the VPL-VW1000ES, the company's first "consumer" 4K projector with a retail price of approximately £12,500. Toshiba also launched a 55in 4K HDTV with a price tag of approximately £7,500.

If you can afford the 4K display, you still need to find media for it. YouTube supports 4K video, but very few people upload video of that quality to the site, and currently no Blu-ray discs contain 4K content. Sony offers a Blu-ray player that can upscale to 4K, but upconverting video doesn't produce nearly as nice a picture as footage recorded at native resolution.

LG will be showing off the new screen at IFA in Berlin next week. It has launched in South Korea, and will be released worldwide in September.
