Since the THX mode of the LG 60PG0, unlike that of the Panasonic TH-50PZ800U, doesn't let you make any changes to the picture, it presents a dilemma: to simply use the THX setting as-is or to take advantage of the extensive Expert menu settings to try to improve upon it. We compared the two by performing our standard calibration of Expert. As it turns out, THX provided the most accurate color once again, mainly because we couldn't get primary colors, especially green and cyan, to come as close to the HD standard as THX did. Expert did deliver a more accurate and linear grayscale, color balance was also better (THX desaturated red), and shadow detail very slightly better, and we were able to get a brighter image out of Expert, but despite these post-calibration advantages, we still preferred the color accuracy of THX overall. That said, we'll let you be the judge: we posted our Expert picture settings at the end of this blog post.
Unfortunately we didn't have any like-size plasmas to pit against the LG in our comparison, so we settled for the usual suspects in the 50-inch size: Panasonic's TH-50PZ800U, Pioneer's PDP-5020FD, and Samsung's PN50A650. We threw in the 52-inch Samsung LN52A650 LCD for good measure and spun up a Blu-ray copy of Blade Runner: The Final Cut on our PlayStation 3 to perform the bulk of our image quality tests.
Black level: As with its 50-inch brother, the 60-inch LG 60PG60 didn't equal the black-level performance of the Panasonic or the Pioneer plasmas. Dark areas, such as the cityscape and letterbox bars during the initial flyover of Los Angeles, appeared a good deal lighter than either of those models, which made the LG's picture appear less impactful. Black-level performance is especially important on a very dark film like this, but the difference in the LG's black levels was also apparent, albeit much less obvious, in lighter scenes or while watching in a more brightly lit room. We wouldn't describe the LG's blacks as washed-out by any stretch, however, and they still appeared about as deep as those of the Samsung plasma.
The 60PG60's shadow detail throughout the film was very good in THX mode, although we felt that the post-calibration Expert mode was a bit better, bringing out the darkest, most subtle details a bit more clearly.
Color accuracy: The largest impact of THX certification, as we mentioned above, was in the arena of primary and secondary color accuracy. The film has a lot of cyan, from the light streaming into the examination room in the beginning to the clouds passing in front of Deckard as he munches noodles. On the LG in THX mode these colors looked natural and accurate, not overly bluish as we saw on the Pioneer plasma or the LG's Expert setting. Greens were also significantly more accurate, as we saw when we turned to a high-def baseball game.
On the flip side we felt that the LG's THX mode desaturated colors, especially reds, slightly compared with that of the Panasonic, which made some colorful areas appear slightly less vivid by comparison. A close-up of Pris as she approached the Bradbury, for example, revealed a bit paler complexion and slightly less punch to her lips and cheeks than we saw on the Panasonic. We also noticed the relatively greener tinge to grayscale when we looked closely, which again showed up in delicate skin tones like the alabaster face of Rachel as she walks toward Deckard in the room atop the ziggurat. The differences in color temperature and color balance (color decoding) were subtle, to be sure, and disappeared when we engaged Expert mode, but in the more accurate THX setting we did notice them. All of the modes on the LG also colored black areas a bit greenish, much like the Samsungs and unlike the Pioneer and Panasonic plasmas.
Video processing: As we've come to expect from LG, the 60PG60 acquitted itself well in this department, deinterlacing both film- and video-based sources properly, delivering every line of resolution from 1080p signals, and squelching excessive noise when we engaged the noise reduction functions. 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).
Uniformity: Unlike with the 50PG60, we didn't notice any more false contouring on the 60PG60 than we did on the other displays, even with Blade Runner's numerous contouring-prone areas, such as the beams of light angling through the smoky room on the ziggurat, or the headlights of the hovercars in the smog.
Bright lighting: LG doesn't tout any sort of antireflective screen on this model, and in our observations the 60PG60 didn't do much to curb in-room reflections glancing off its massive glass screen. All of the other plasmas in our test, to a greater or lesser degree, did a better job at dimming light from in-room sources such as lamps or an open window, and all did a better job of preserving black levels in bright rooms without washing out.
Standard-definition: The 60PG60 did very well in our standard-definition tests. The set resolved every line of the DVD format, and details in the stone bridge and grass looked relatively sharp. We appreciated that rotating diagonal lines were smooth with very few jaggies, as were the stripes of a waving American flag. In THX mode, the noisy shots of sunsets and skies looked clean, while the four-step control available in other picture modes 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 HDMI in THX mode the LG 60PG60 performed as well as we expected, resolving every line of a 1,920x1,080 source with no overscan and clearly legible text with very little edge enhancement. We were pleasantly surprised to see the same excellent performance via the analog VGA input.
