One of our favorite HDTVs of 2008 was the
Samsung LN52A650 , which has remained in our lab for more than a year as a comparison model representing LCD TVs that use a conventional backlight as opposed to LEDs. Now that 240Hz processing has arrived in force on the LCD landscape, we expect the Samsung LNB750 series to take up that mantle. This set outperforms the company's edge-lit LED-based LCD displays in most areas, including black-level performance and picture uniformity, and produced a better picture than any other LCD we've tested, aside from last year's LED-backlit models that utilize local dimming. It's definitely not perfect, however, and the best plasma displays still equal or surpass this LCD in overall image quality. But for people seeking an LCD and willing to pay a premium for 240Hz and interactive extras, the Samsung LNB750 series should make the short list.
Design
The LNB750's coloration will attract less attention than that of most other members of Samsung's Touch of Color oeuvre. The faintest tint of translucent blue appears along the bottom edge of the frame, highlighted by the company's trademark, and happily defeatable, illumination directly below the logo. The rest is glossy black fronted by see-through plastic that extends beyond the edge on all four sides--althou gh if you stare hard enough at the extreme edge of the frame, you might convince yourself it has a touch of blue too. In all we found the look tasteful and appealing, although we still prefer narrow-bezel sets such as the
Sony KDL-XBR9 series.
Like Samsung's substantially thinner edge-lit LED-based LCD models, the 3.1-inch-deep
LNB750 has a slick stand with a glass base and transparent stalk that gives provides the impression of a floating panel. As always, we appreciate the swivel action.
Samsung used the same menu system as last year, this time with ice-blue borders, and we still think it's one of the best in the business. Big, highly legible text is set against transparent backgrounds that occupy almost the whole screen. Getting around is easy, and there's helpful explanatory text along the bottom to describe the different selections.
The remote control is basically the same as last year's, too, aside from a new protrusion on the rear that keeps the clicker stable on a flat surface, and we're definitely fans--especially since Samsung ditched the rotating scroll wheel. The buttons are big, backlit, and easily differentiated by size and shape, and we liked the dedicated "Tools" key that offers quick access to picture and sound modes, the sleep timer, and the picture-in-picture controls. We didn't like the remote's glossy black finish, though, which picked up more than its share of dulling fingerprints after a few minutes.
Features
The LNB750 series' major step up over the less expensive
LNB650 models is the inclusion of a 240Hz refresh rate, which is twice as fast as the 120Hz refresh rate found on many other sets. The main impact of the faster refresh rate is improved motion resolution, although the improvement will be hard to see for most viewers. Samsung's Auto Motion Plus dejudder processing is also on-board, and new for 2009 it includes a nicely implemented custom setting that lets you tweak blur reduction and judder. See Performance for more information.
Samsung has added Yahoo Widgets to its higher-end sets including the
LNB750 series.
The system gathers internet-powered information nodules, called "snippets," into a bar along the bottom of the screen. The model we reviewed came with widgets for stocks, weather, news and Flickr photos, plus Yahoo video, sports scores, poker, trivia and Twitter--and more are sure to appear in the near future. For more information, check out our full review of Yahoo Widgets. That review was based on our experiences with a
Samsung UN46B7000, and our impressions of the system on the LN52B750 are mostly the same, including its sluggish response time.
Other interactive features on this set abound. It can stream videos, photos and music from DLNA-certified devices via the network connection, as well from its USB ports, which can connect to MP3 players, USB thumbdrives and digital cameras (we didn't test this capability). There's also built-in "content," such as recipes, games, workout guides and a slideshow of high-def art and photos with music. We went into depth discussing the underwhelming content features last year, which are similar this time around, so for more details check out the Interactive section of the 2008
Samsung LN46A750 review.
The LNB750 series offers very good connectivity , although it does follow the recent trend of spurning S-video inputs--not one is to be found on this TV. The back panel sprouts three HDMI ports, two component video inputs (one of which can be sacrificed for composite video, if you need it), one VGA-style PC input, one RF input for cable and satellite, the Ethernet port, and one stereo analog and one optical digital audio output. The TV's side panel offers a fourth HDMI, two USB, and one AV input with composite video.
Black level: The overall depth of black achieved by the
Samsung LNB750 surpassed that of the other LCDs, including the company's own edge-lit model in all but the darkest scenes, although it wasn't as dark as that of the plasmas. The closest competitor was the Sony XBR9, but in very dark areas--like the building in the foreground, the letterbox bars and Jude's black leather jacket during the alleyway goodbye tryst in Chapter 3--the B750 got just a bit darker. Its black levels were significantly deeper than either the A650 or the Toshiba, and closer overall to the other sets.
Details in shadows looked a bit more-obscured than we saw on the plasmas. From the same scene, for example, Jude's hair, the folds on his jacket and the reluctant face of his Liverpool girlfriend seemed a bit less natural in their progression from shadow to light. Compared to the other LCD displays in our lineup, however, the B750 fared better, coming closer to the reference display than any of them. The difference was subtle between the XBR9 and the B750, however.
Color accuracy: As we've come to expect from higher-end Samsung TVs, the B750 performed very well in this area. Like the Sony, its primary and secondary colors were nearly perfect, as evinced by the lush yet-not-neon trees and grass of the campus in Chapter 4, or the appropriately garish reds and blues of the costumes during the Mr. Kite number. That scene also showed off the B750's solid color saturation. The image didn't have quite the same level of "pop" as the plasmas, but it looked better than either the A650 or the Toshiba and similar in saturation to the 7000 and the XBR9.
Skin tones looked mostly good, although we did see a very slight bluish cast in midtones. The close-up face of Sadie as she faced her mother after the bad tidings in Chapter 8, for example, seemed just a bit too pale compared to our reference plasma, although still better than the greenish cast we saw on the G10 and, to a lesser extent, the XBR9. We noticed similar differences in the Chapter 16 scene with the human flower, which provided a nice skin tone cornucopia. We also appreciated that the dark areas on the B750 looked closer to true black than on the bluish 7000 or the greenish A650, although they were still pretty blue--more so than the XBR9.
Video processing: The effects of the 240Hz refresh rate on the LNB750 were similar to what we saw on the Sony models--in other words, difficult to discern (at best) when watching regular program material, but providing a noticeable reduction in blurring during test patterns. The main difference between the two, and what makes the Samsung better than the Sony, is the former brand's ability to remove dejudder processing while keeping blur reduction.
With the Sony and most other dejudder-equipped 120Hz and 240Hz displays we've tested, you must engage the smoothing effect of dejudder if you want to minimize blur. With 2009 Samsungs, you can separate the two using the Custom setting. In fact, we got the best results by choosing Custom and setting blur reduction at 10 and judder reduction at zero. The Custom mode worked as we expected; as we decreased the blur reduction slider, the display delivered fewer lines of motion resolution. As we increased judder reduction the image took on more smoothness and also more artifacts. Compared to the 240Hz Sony the Samsung appeared just the tiniest bit sharper--although both resolved between 900 and 1,000 lines, the Samsung showed fewer artifacts on our test pattern. The LNB750 also outperformed the Toshiba on this test, although it looked less pristine than the Panasonic plasma.
Uniformity: The screen of the LNB750 is more uniform across its surface than many LCDs we've tested, including the Samsung 7000, the Toshiba, and the Sony XBR9. It didn't suffer from overtly brighter corners as the 7000 and the XBR9 did, although in flat field test patterns we did notice the edges of the LNB750's screen appeared slightly brighter than the middle.
The LNB750 did seem to wash out and lose black-level depth a bit faster than the XBR9 when seen from off-angle, however, although it didn't become too discolored nor wash out as quickly as did the 7000.
Bright lighting: Samsung used the same sort of glossy screen as last year, and we're not its biggest fans. In bright lighting, with windows facing the screen and overhead lights turned on, the screen does a very good job of preserving black levels in dark areas. However, the trade-off is overly bright reflections from those light sources and from other bright objects in the room, such as this reviewer's shirt. These reflections were much less bothersome during bright scenes, of course, but in darker scenes they proved distracting.
Standard definition: The LNB750 evinced generally solid standard-def picture quality. According to our tests the display handled every line of a DVD source and the shots of grass and steps from the detail test looked good. The set eliminated jaggies from video-based sources well, and its noise reduction cleaned up the lowest-quality shots of skies and sunset with aplomb. Finally the UNB7000 passed 2:3 pull-down test by eliminating moire from the stands behind the racecar.
PC: Samsung's LNB750 series delivered excellent performance with HDMI sources from computers, resolving every line of a 1,920x1,080 image with no overscan or edge enhancement. The image did appear softer via VGA, and resolution wasn't quite full, but it was still very good.
