  • More Pixels + Bigger Screens = More Power Consumption

    November 17, 2015

    I don't often hear the words "National Resource Defense Council" and "Ultra HDTV" in the same sentence.

The NRDC report goes on to say that one-third of all new TV purchases are for screens 50 inches and larger, which should come as no surprise given how dramatically TV prices have dropped in the past three years.

The technology is "immersive sound," and it goes considerably beyond the 5.1-channel surround sound with which we are all familiar.
