NEW YORK -- High-definition TVs roughly quadrupled the resolution of the sets that came before. Now, the industry is poised to do it again.
By December, U.S. stores will sell TV sets with four times the resolution of the best HDTVs, Sony Corp. said Wednesday. The set will measure 84 inches on the diagonal, making the screen area four times as large as 42-inch sets.
Sony expects to reveal the set's price next week.
The higher-resolution set has been dubbed "4K" because it has nearly 4,000 pixels on the horizontal edge.
