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 UHDTV sets available worldwide, but given the price, that should be sufficient to satisfy the Christmas demand.
