LG 50PG30 review (50" plasma TV)

Performance
All told, the LG 50PG30 is a middling performer among 1080p plasmas, exhibiting average black-level performance and inaccurate color decoding and primary colors. We had no problems with its video processing and resolution, and standard-definition performance was among the best we've tested, but compared with the competition, the 50PG30's picture does little else to distinguish itself.

Myriad picture controls allowed us to tweak the picture but didn't help enough. We were able to improve the grayscale somewhat, which measured a bit red and plus-green in the Warm mode default, but tracking after calibration was still not as linear as we'd like, especially at the bottom of the scale (darker areas), which veered from reddish to bluish and back. The set's color management system was a disappointment. Primary color, especially green, remained well outside the HD standard no matter what we did to the controls, while the set's incorrect color decoding was also impossible to fix and still leave color balance natural (we ended up simply zeroing out the individual saturation controls for primary and secondary colors). Check out the end of this blog post for our complete picture settings.

After setup, we lined the LG up amid a few other HDTVs we had onhand, including the similarly priced Samsung PN50A650 as well as a few current reference sets, namely the Pioneer PDP-5020FD and the Panasonic TH-50PZ800U, both 50-inch plasmas, and the Samsung LN52A650, a 52-inch LCD. For the majority of our image quality tests, we spun up a copy of Daredevil on Blu-ray in our PlayStation 3 and settled back to see how the LG compared.

Black level: The depth of black produced by the LG was about as dark as that of the Samsung PN50A550 but not as deep as that of the Panasonic and Pioneer plasmas. When young Daredevil runs after his father into the dark alley, for example, the black of the letterbox bars, the car tire and the asphalt in the alleyway appeared dark and realistic enough, although side-by-side with the better plasmas they looked a bit too bright. The Samsung LCD, for its part, also appeared lighter than any of the plasmas in these scenes. Details in the shadows, such as the side of the Dumpster and the folds in the father's clothes, were a bit brighter than we'd like to see; the rise from black to lighter shadows was a bit abrupt compared to that of the other displays, although the difference wasn't tremendous.

Color accuracy: The LG didn't score all that well in this category. Primary colors, first off, veered away from the HD standard, so the green leaves on the plants in the playground where Daredevil meets Jennifer Garner, for example, looked decidedly yellowish compared with the Panasonic and the Samsungs. The blue sky looked a bit darker than on the other sets too, which spoke to the LG's less-accurate secondary color of cyan.

As we mentioned above color decoding was also a problem, and as a result Garner's skin appeared a bit pale and undersaturated compared to the other colors and the other displays, no matter which adjustments we made to the main color control or the color management system. In dark scenes, such as the pan over the church in the beginning, we noticed that near-dark areas took on a significant bluish tinge; the bricks on the church walls looked as if they'd been bathed in bluish light, and lacked the neutral grayish color seen on the other displays. We did appreciate that black itself stayed neutral on the LG, but we didn't notice too many other positive aspects to color reproduction.

Video processing: The LG correctly deinterlaced film-based sources from both film and video, and naturally it resolved every line of 1080i and 1080p sources. We noticed a bit more video noise in noisy scenes with NR turned off than on the other displays, but engaging noise reduction cleaned that up with no apparent loss in resolution. We measured a motion resolution of between 800 and 900 lines on this set, which is about what we expect from a 1080p plasma, although as always we didn't notice any blurring during the film, even with the Samsung LCD (120Hz dejudder turned off).

It's also worth mentioning again that at a 50-inch screen size, the difference in resolution between a 1080p plasma and its 720p (actually, 1,366x768) counterpart is very difficult to discern with normal high-definition program material, whether 1080p or otherwise.

Bright lighting: In a bright room the LG reflected more ambient light than any of the other displays aside from the Samsungs, which occasionally became distracting when viewing dark scenes with the window shades up, for example. Unlike the Samsungs, dark areas also washed out more readily on the LG, and to a greater extent then the other displays as well. Overall the screen of the 50PG30 didn't exhibit very effective antireflective properties.

Standard-definition: On the other hand, our tests revealed very good standard-definition picture quality from the 50PG30. The set resolved every line of the DVD format, and details in the stone bridge and grass looked relatively sharp. In terms of jaggies, we appreciated that rotating diagonal lines looked quite clean, as did the stripes of a waving American flag. The four-step control noise reduction control worked well to remove motes of snow and other video noise. The LG also engaged 2:3 pull-down detection quickly and effectively, eliminating moire from the stands behind the racecar.

PC: Via both analog VGA and digital HDMI, the LG 50PG30 accepted and displayed every line of a 1,920x1,080-pixel resolution signal according to DisplayMate. That's great, but text and other lines on the screen appeared softer than we expected, with some edge enhancement we couldn't reduce. PC performance was therefore just average.
