Toshiba Corp announced the "Regza 55X3," a 55-inch LCD TV capable of displaying "4k2k" (3,840 x 2,160-pixel) 2D video and 3D video viewable with the naked eye, Oct 3, 2011.

The 55X3 is a domestic model of the product announced at IFA 2011 in September 2010 in Germany. It will be launched in mid-December 2011 in Japan. Though there is no manufacturer's suggested retail price, its price is expected to be about ¥900,000 (approx US$11,716). Toshiba is planning to manufacture 1,000 units per month.

"4k2k is clearly different from 2k1k (1,920 x 1,080 pixels)," said Masaaki Osumi, Toshiba's executive officer, corporate senior vice president and president and CEO of Digital Products & Services Company of Toshiba Corp, commenting on the aim of releasing the 4k2k TV. "It is true that some people wonder if it is really necessary. But we want to realize video of dreams."

As for the naked-eye 3D display, he said, "Though it is OK to use special glasses in theaters, it is uncomfortable to use them at home. We want to provide stress-free 3D video."

Creating 4k video

The 4k2k video, which is one of the features of the 55X3, is created from input video by using the "Super-resolution Processing," which Toshiba has developed for its Regza series of LCD TVs. Video of terrestrial digital broadcast (1,440 x 1,080 pixels) and DVD video (720 x 480 pixels) are first converted to full-HD video (1,920 x 1,080 pixels). Then, based on the full-HD video, 4k2k video is created. The 4k2k video is vertically divided into two parts and output to the panel.
