LG Launches World's Largest 4K TV

An 84-inch, 4K TV screen has been released and is being described as the world's largest ultra-definition TV.
LG Electronics released the screen, which offers 8m pixels per frame - that's four times the resolution of 1080p high-definition displays.
LG's UD 3D TV has a 2.2 speaker system consisting of two 10W speakers and two 15W woofers for a theatre-like experience.
And the company said the release would help it "claim a stake" in the 4K market.
Toshiba and Panasonic already offer 4K screens (at 55in and 20in respectively) and both Sony and Samsung are developing devices.
The chief executive of LG Electronics Home Entertainment, Havis Kwon, said: "The 4D display market is still in its infancy but it was important for LG to claim a stake in this space. LG's UD 3D TV represents a whole new level of home viewing experience because it offers every advanced technology we currently have to offer."
The 84in model has been released in South Korea, LG's home, ahead of its worldwide launch in September.
It will also be on display at the IFA technology trade show in Berlin in August.
