LAS VEGAS — As promised, LG has unveiled its quantum-dot TV.

The UF9400, unveiled at CES in Las Vegas, is one of the first TVs to incorporate the tech, which is said to enhance color greatly.

The 65-inch TV is fundamentally an LCD panel, but it incorporates a layer of quantum dots, which are extremely small (as tiny as 20 atoms thick) "nanocrystals." The size of the crystals determines the color of a pixel, and that size can be controlled precisely.

The result: extremely accurate color reproduction, potentially as much as 30% better than regular LCDs. Quantum dots are part of LG's proprietary ColorPrime tech, which also boasts improved color at off-angle viewing — a recurring problem with many LCD sets.

And yes, the panel is 4K. The TVs Ultra HD resolution (3,840 x 2,160) has four times the pixels of a full HD panel, plus it's equipped to handle 4K signals at 60p as well as the newer H.265 codec, letting you stream 4K video without choking your Internet connection.

LG's webOS 2.0 smart TV interface and Harman Kardon speakers are also on board.
