Sony flows 120Hz down to lower price points

The mainstream Sony KDL-V5100 series of flat-panel LCDs include a 120Hz refresh rate with dejudder processing, also known as MotionFlow.

Formerly a feature reserved for high-end HDTVs, 120Hz with dejudder is becoming more common at for less money, as evinced by Sony's 2009 KDL-V5100 series of flat-panel LCDs.

The V-series of Sony LCDs is the company's least-expensive with 120Hz processing. Sony

The three-size V-series includes the 52-inch KDL-52V5100, the 46-inch KDL-46V5100 and the 40-inch KDL-40V5100. Each offers the company's dejudder processing , known as MotionFlow, that we've reviewed in models such as the KDL-46W4100 from 2008. While we're not big fans of dejudder processing in general, some viewers like the smoother look, and Sony's version performs relatively well.

Other features of the V-series include 1080p resolution, four HDMI inputs, a PC input and compatibility with a range of Sony proprietary add-ons like the Bravia Internet Video Link.

Sony is also touting the TVs' energy efficiency, saying they exceed Energy Star 3.0 and highlighting their light sensor and variable backlight features.

The KDL-V5100 sets will be available in spring for prices yet to be determined. Sony also announced higher-end Z-series and XBR9-series models.
