Toshiba has another first on their hands with the 55-inch Cell Regza 55X1, the first LCD HDTV to be equipped with a Cell chip. The 55X1 offers a peak luminance of 1250 cd/m2, LED backlighting, a dynamic contrast ratio of 5,000,000:1, a resolution of 1920 x 1080 pixels, 240Hz scanning, and Super Resolution technology which makes use of Cell power for greater image quality.

Some other features include a 7-speaker sound bar, DLNA support, an internet browser from Opera Software, HDMI and USB, and an SD card slot. You also get a ‘tuner box’ with 3TB of storage space, 2TB of that will be devoted to the “time-shift machine” feature, which can simultaneously record up to 26 hours of programming on up to eight channels.

Toshiba has already begun shipping their Regza HDTVs, which were initially shown off at CES earlier this year. They even added another series to the line up today, called the XV648. First, the SV670 features an LED backlight, a 240Hz panel, 2,000,000:1 contrast ratio, 14-bit color processing and more. It comes in 46-inch and a 55-inch versions that will cost you $2,300 and $3,000.

The ZV650 features a CCFL backlight rather than LED and has a 240Hz panel and a 100,000:1 contrast ratio. It comes in sizes ranging from 42-inches to 55-inches and costs from $1,300 to $2,400. Then there’s the XV648, which is new to the Regzas line and features a CCFL display, a 120Hz panel and a CrystalCoat display for better contrast.
