LG on Wednesday introduced the LH90 series of 1080p LCD HDTVs featuring LED backlighting and THX Display Certification. Each TV supports contrast rations up to 2,000,000:1, while TruMotion technology converts the refresh rate to 240Hz. The integrated THX Movie Mode is designed to optimize the color, black levels and signal processing.

LG claims the LH90 series meets Energy Star 3.0 specifications, while a light sensor can automatically adjust the backlight settings to fit the ambient light levels in a room. A picture wizard enables further calibration, with on-screen reference points for elements such as black level, color, tint and sharpness.

The LH90 series includes a 42-inch screen for $1,900, a 47-inch variant for $2,400 and a 55-inch model for $3,200.
