The Good Accurate color; extensive picture controls including unique Picture Wizard; adequate connectivity with three HDMI and one PC input; energy-efficient.

The Bad Reproduces relatively light black levels; below-average uniformity and off-angle viewing; no S-Video input.

The Bottom Line While its black levels and uniformity mark the LG LH30 series as an entry-level display, its extensive picture controls allow the color accuracy of a flagship model.

Editors' note (March 4, 2010): The rating on this product has been lowered because of changes in the competitive marketplace, including the release of 2010 models. The review has not otherwise been modified. Click here for more information .

The 2009 entry-level LH30 series of LCD TVs re-establishes LG as the king of picture controls. Last year the company offered the most extensive suite of user-menu color adjustments available and this year there's even more to tweak--from gamma targets to color filters to a Picture Wizard, designed for nonexperts, with built-in test patterns that actually work. The end result is highly accurate color. But other major picture quality factors, namely black level and screen uniformity, are generally beyond the reach of controls, and in the LH30's case those two factors weigh heavily. Nonetheless, if you want a high degree of color accuracy and customization in an otherwise basic LCD TV, the LH30 is mighty appealing.

We performed a hands-on evaluation of the 42-inch 42LH30, but this review also applies to the other sizes in the series: the 47-inch 47LH30, the 37-inch 37LH30 and the 32-inch 32LH30. All of the sizes share identical specs and should provide very similar picture quality.

Design
If you're looking for relief from the scads of identical-looking glossy-black HDTVs out there, don't look to the LH30 series. The straightforward exterior has the same medium-width gloss-black frame on the top and sides with a thicker portion below the screen, the bottom edge of which is curved ever so slightly and edged by a chrome-colored strip. LG's characteristic subtly protruding, illuminated power indicator interrupts the strip on the right side, and speakers are hidden completely from view along the bottom of the panel. The stand swivels and matches the panel with its glossy black.

LG LH30 series
The LG LH30's one distinguishing accent is the power indicator protrusion.

The company cut corners on the entry-level remote control. Our biggest hang-up was lack of a dedicated aspect ratio button, and we couldn't get used to the placement of the menu key to the lower-left of the big cursor control. There is a prominent, appropriately colored key toward the top labeled "Energy Saving," complete with leaf logo, but somewhat confusingly it calls up the rotary-looking quick menu, set to the energy saving position, instead of a completely separate energy saving function. On the plus side, we liked the feel of the clicking, rubberized cursor control.

A prominent Energy Saving key on the remote offers easy access to that setting in the Quick Menu.

LG's menu system is quite extensive, so the easy-access quick menu for aspect ratio, picture and sound modes, the timer and other oft-used functions, is welcome. The main menu is laid out the same as last year with the addition of a new onscreen "simple manual" that provides basic setup and function information. One miscue: we'd really like to see explanations of menu items appear onscreen, too, especially since many of them are so advanced.

The rotary Quick Menu circumvents the main menu and offers a direct route to major functions.

Features
As LG's entry-level line of 1080p resolution LCDs, the LH30's big missing feature compared with the step-up LH40 models is 120Hz with dejudder processing.

On the flipside, the LG LH30's picture-adjusting controls certainly surpass those of most entry-level HDTVs. 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 you 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. See the Performance section for details on the results.

The picture wizard's series of screens is each devoted to adjusting one picture parameter, such as black level (the brightness control).

Each of the eight adjustable picture memory slots is independent per input, and we appreciated that all of them, aside from the two Expert slots, indicate whether they're in the default settings. Advanced controls abound in even the nonexpert modes, with three color temperature presets, settings for dynamic contrast and color, noise reduction, three levels of gamma, a black level control, wide and standard color spaces, edge enhancement, a room-lighting sensor, and even an "eye care" setting designed to prevent the screen from being too bright (it's disabled in Vivid and Cinema modes).

LG LH30 series
The Advanced picture controls available in most picture modes are just the tip of the iceberg.

Those Expert modes, which bear the logo and the input of the Imaging Science Foundation, offer a passel of additional controls. Our favorite, first introduced by LG last year and still exclusive to the company, is a 10-point white balance system that can really help get a more accurate grayscale. The company upped the ante for 2009, adding the capability to target a 2.2 gamma, internal test patterns, and even color filters for blue-only, green-only, and red-only to help set color balance. A full color management system is also on-tap, and we love the capability apply Expert settings to all inputs or just one at a time. Of course, most of these settings will appeal only to pro calibrators and HDTV geeks, but either way, LG's 2009 models offer the most complete suite of user-menu picture adjustments we've seen on any HDTV to date.

The Expert picture modes offer a 10-point white balance option, which has been improved from last year.
