At a press event in New York City last night, Sony showed off a new three-model NX810-series of 3D LCD TVs, which will be available next month. The sets, which all use edge LED backlights that can be locally dimmed, range in price from $2,700 to $4,700.

The 3D TVs will be available in 46-, 55-, and 60-inch screen sizes, and all include Sony's Motionflow 240 Pro 240Hz technology, built-in Wi-Fi, and its Bravia Internet Video online service. All include a built-in sensor that adjusts the backlight to room lighting conditions.

Like the two Sony 3D models we've so far tested—see First Look: New 3D LCD TVs from LG, Sony for our assessment of the sets—these TVs work with Sony's 3D glasses, which unlike other glasses we've tested use just a single polarizer for each lens. As a result, we expect them to perform similarly in the 3D mode to the sets we've already seen, which require viewers to keep their heads completely vertical to the screen or significant ghosting (double images) can occur.
