FILE - This undated publicity image provided by Sony shows an ultra-HD 4K TV set. High-definition TVs roughly quadrupled the resolution of the sets that came before them. Now, the industry is poised to do it again as Sony says its U.S. stores will, by December 2012, sell a TV set with four times the resolution of today's best HDTVs. The new, restored and rebooted films from Sony Pictures are among the content coming pre-loaded on a video player bundled with Sony's first ultra-high-definition television, a massive 84-inch set that retails for $24,999.99 and features nearly four times the resolution of typical high-definition TVs.
