At CES 2015 -- now less than a month away! -- LG says it will show off a 55-inch 8K TV, and a 4K TV that uses quantum dots to improve image quality and color saturation. The 8K display is also notable because it's small -- with a diagonal of 55 inches, this thing not only has an incredibly high resolution for a TV (160 PPI), but it will actually fit in most households, unlike the 85- and 98-inch 8K TVs that we've seen previously.
