LG 42LH55 first look

At CES this year, LG made a big deal out of its 240Hz technology, claiming it bested similar blur-busting tech from other LCD makers. The LH55 series represents the company's least-expensive HDTV equipped with a 240Hz refresh rate, and when it comes to that feature, as usual, we weren't particularly impressed. The results were similar to those seen on other 240Hz displays--reduced blur that was difficult for us to really discern, although test patterns prove it's there--but we were a bit annoyed that you have to engage the smoothing effect of dejudder if you want to reduce blur. In its favor, the LH55 brings a boatload of other picture quality adjustments to bear, most of them leading to excellent color accuracy, but its overall picture is hampered by lighter black levels, among other minor problems. If you can handle those issues, are sensitive to blur and enjoy picture tweaks, the LH55 is one of the more tempting LCDs out there.

Series note: We performed a hands-on evaluation of the 42-inch LG 42LH55, but this review also applies to the other sizes in the series, namely the 37-inch 37LH55, the 47-inch 47LH55, and the 55-inch 55LH55. All sizes share identical specs and features and should provide very similar picture quality.

Features
As we mentioned above, the LH55's main step-up feature is a 240Hz refresh rate, which is designed to combat blurring in motion. There are two species of 240Hz and LG employs the "scanning backlight" variety, which augments the usual 120Hz technique of doubling the standard 60-frame signal with a backlight that flashes very rapidly on and off (much faster than humans can perceive) to help reduce motion blur. In our tests the other 240Hz technique, which actually quadruples the standard signal and is used by Sony and Samsung, produced slightly better results than LG's method, which is also employed by Toshiba and Vizio. Unlike Toshiba, which carefully calls the scanning backlight a "240Hz effect," LG's marketing department has no qualms about touting its method as unqualified 240Hz.
LG's implementation of dejudder is similar to past 120Hz and 240Hz displays, which force you to engage the smoothing effect of dejudder if you want to enjoy the benefits of reduced blurring. 2009 models from Samsung and Toshiba, on the other hand, allow you to separate the two functions, an option we really prefer to have. The LH55 series offers two strengths of dejudder, Low and High, and also offers a separate "Real Cinema" function designed to work with 1080p/24 sources. Check out the performance section for more details.

Like other LG displays, the picture controls on the LH55 series surpass most of the competition. The company included even more adjustments than last year, starting with a well-thought-out Picture Wizard that uses internal test patterns to help you perform your own basic calibrations of the controls for brightness, contrast, color, tint, horizontal and vertical sharpness, and backlight. Once you've finished, your settings are saved to the Expert1 picture memory slot for your choice of inputs.
