Sony says that by December, U.S. stores will sell a TV set with four times the resolution of today's best HDTVs. The set will measure 84 inches on the diagonal, making the screen area four times as large as the common 42-inch set.
Sony executives didn't reveal the price of the set Wednesday.
There is, for now, very little video content available that can take advantage of the higher resolution. With some work and know-how, a computer connected to the set can display video in the ultra-HD "4K" resolution. The set will also do its best to "upscale" TV, DVD and Blu-ray movies, so they look better.
