LAS VEGAS — For LG, it wasn’t enough to build a big 77-inch 4K TV with a curved screen. It also upgraded the display technology itself by adding a fourth subpixel to every one of the 8+ million pixels in the display.
While most TVs have three subpixels (red, green and blue or RGB), the LG 77EC9800 adds a fourth white one (WRGB). LG isn’t the first manufacturer to offer four-pixel screen tech — Sharp has been doing it in its Quattron line for years — but it’s the first time we’ve seen it applied to a 4K set.
The advantage of having four pixels is improved color accuracy and contrast. In fact, LG claims its 4K wonder has “infinite” contrast, meaning the blacks are as black as can be. Also, the TV’s Color Refiner tech keeps a constant watch on every pixel, adjusting color temperature as necessary to maintain a smooth and consistent picture.
The set also has all the regular 4K goodness, with 3,840 x 2,160 pixels, and LG’s Tru-Ultra engine upconverts all video to that resolution. The set is equipped with HDMI 2.0, so it can handle full 4K video at 60 frames per second, and it’s compatible with HDCP 2.2 content security as well as high-res videos in the H.265 format. It’s also capable of displaying 3D content, should you care.
LG is also building a new smart TV interface based on webOS, which gives the set direct access to services like Netflix and Hulu Plus, no set-top box required. LG says webOS enables fast transitioning between services, and it’s compatible with many open-source technologies (such as webkit), so we could potentially see many apps on the platform eventually.
LG’s quad-pixel 4K TV will be ready and waiting for your living room/man cave by the summer for the tidy sum of $29,999.
