Insignia NS-L42X-10A
Not everyone has the need—or the budget—for the latest and greatest in television technology. Features such as LED backlighting, 240Hz refresh rates, and Web connectivity are all the rage right now, but as is usually the case with new tech, you’ll pay a premium for it. Enter the Insignia NS-L42X-10A, one in a series of four low-cost 1080p 120Hz HDTVs offered exclusively by Best Buy. Priced at $749.99, this 42-inch LCD model may not offer much in the way of features or aesthetics, and its picture quality is less than perfect, but if you’re looking for a cheap, no-frills flat-screen TV for, say, the basement, or a playroom, it’ll fit the bill.
Design and Appearance
The 42-inch panel is housed in a plain-looking black cabinet. The display is bordered by a relatively wide glossy black bezel on three sides, and an extra-wide lower bezel which curves upwards at the bottom. I’m not a fan of the design: it looks a bit flimsy and lacks the clean lines found on much-pricier models such as the LG 42SL80 and the Toshiba Regza 46SV670U. The matching stand is fairly stable and does a good job of supporting the 37-pound screen, and it swivels so you can position the display for optimal viewing. The two 12-watt speakers provide plenty of volume, and the SRS TruSurround feature does a fairly good job of simulating a multi-channel audio experience, but you’ll need a subwoofer if you want pumping bass, since you won’t find any here.
Recessed into the right side of the cabinet are buttons for powering up the set, changing channels, selecting an input source, raising and lowering the volume, and accessing the on-screen menu system. On the left are two of the five HDMI ports, VGA (PC) and S-Video inputs, a PC audio input, composite audio and video ports, and a headphone jack. Around back are three additional HDMI ports, two sets of component audio and video inputs, a digital (SPDIF) output, one set of analog stereo audio outputs, a secondary S-Video input, and a secondary set of composite A/V inputs. While it’s nice to have five HDMI ports, you won’t find a card reader, Ethernet, or USB ports—features which can be found on many of today’s midrange models such as the Sharp Aquos LC-40LE700UN and the Toshiba 46SV670U.
The 52-button remote is tapered in the middle and fits comfortably in your hand, but it’s a bit on the small side and the buttons feel slightly crowded. The four-way rocker is very responsive, however, making it easy to zip through the on-screen menus. The uncomplicated menu structure is broken into four basic submenus; Picture, Audio, Channels, and Settings. The Picture section is where you can tweak brightness, contrast, sharpness, color, and tint levels. In the Advanced video menu you can adjust backlighting and color temperature settings and enable/disable noise reduction and dynamic contrast ratio functionality. Here you can also choose one of three Digital Clear Motion levels (DCM), which uses 120Hz technology to help reduce motion blur, or you can disable the feature altogether. There’s also a switch that enables a light sensor, which adjusts the screen’s brightness according to the ambient lighting environment. I suggest leaving this feature off; in my tests, the luminance level, which changed often, was very distracting.
The Audio menu provides settings for bass, treble, balance, and SRS TruSurround as well as a dynamic volume setting that compensates for sudden changes in sound level during broadcasts. The Channels menu lets you hide channels and create a favorites list, and the Settings menu is where you can set up parental controls and assign a parental-control password.
Image Quality and Performance
After a darkroom calibration using the DisplayMate for Windows Multimedia Edition diagnostic software, the NS-L42X-10A turned in a contrast ratio of 3207:1, which is quite good for an HDTV that uses CCFL backlighting. It takes more than a high contrast ratio to deliver a high quality picture, though. Greens and blues were saturated, resulting in uneven skin tones and tinting in certain shades of gray. The high contrast ratio helped deliver deep blacks, but I noticed significant motion artifacts in the form of background noise while watching scenes from The Matrix in standard definition. There was a fair amount of image smearing as well. Not surprisingly, the panel was unable to pass the HD HQV Jaggies benchmark, which tests de-interlacing performance.
The set fared better with 1080p HD content. Mission: Impossible 2 on Blu-ray was sharp, but once again I observed subtle smearing and some judder, particularly during the opening rock climbing scene where the camera is continually panning. Enabling the DCM feature helped reduce the judder effect, but the resulting picture looked too sharp and overly noisy. In my tests, viewing angles were fine up to around 165 degrees off center; after that, colors began to fade.
The NS-L42X-10A draws an average of 220 watts, which means it’ll cost around $3.60 a month to run (based on five hours of daily use using the 2008 national average cost of $0.1135 per kWh). While not as energy efficient as some of the newer LED-backlit HDTVs like the 40-inch Sharp LC-40LE700UN, which draws only 120 watts, it’s far from a power hog. Whereas most HDTVs come with a one-year warranty, Insignia provides a two-year plan at no extra cost.
Overall, the big draw of the Insignia NS-L42X-10A is its rock-bottom $750 price. Even in these days of freefalling HDTV prices, it’s tough to find a 1080p 42-inch set for less, let alone one with a two-year warranty. It’s certainly not the sexiest-looking model you’ll find, and its performance is pretty much what you’d expect from a low-cost HDTV, but despite these shortcomings, its low price, two-year warranty, and plethora of HDMI ports help to redeem the NS-L42X-10A . That said, if you have a few extra bucks to spend, the 40-inch Sharp Aquos LC-40LE700UN offers better performance and a more robust feature set, and can be had for around $950 online.
