LG and Sony have both introduced Ultra high definition (UHD) TVs with 84-inch screens within the past three months and both are priced at US$20K or more. These monster televisions have 16:9 aspect ratio UHD screens (3840 x 2160 pixels). There are no more than a few hundred sets available worldwide, but even if a Christmas miracle happens and an 84-inch UHDTV makes its way under your tree, finding a video source to match the screen resolution could prove to be the real challenge.
