The KDL-52EX700 uses edge LED lighting; instead of placing a full array of LED backlights behind the screen, this model places its LEDs around the edges of the screen and directs the light inward. The two primary benefits to this approach are improved energy efficiency and a super-slim cabinet. This TV uses the BRAVIA Engine 3 and offers Motionflow 120Hz technology to reduce motion blur and film judder. It's EnergyStar 4.0-certified with a number of energy-saving options, including a Presence Sensor that automatically turns the TV off when there's no movement in the room for a designated amount of time. It supports DLNA media streaming from a networked server, and it features Sony's BRAVIA Internet Video platform, with access to Netflix and Amazon VOD, YouTube, Slacker Radio, and many more. The KDL-52EX700's MSRP is $2,199.99, but it is available from www.sonystyle.com and other outlets for less than $2,000.
As I mentioned, one of the benefits of an edge-lit LED design is the ability to create a super-slim panel. Indeed, the KDL-52EX700 is impressively slender, given its 52-inch screen size. The TV measures just 2.625 inches deep at its bulkiest point in the center; the edges are even slimmer, measuring less than one inch. The panel weighs just 59.5 pounds with the stand (compare that with my 46-inch reference LCD, which is just two years old and weighs 77 pounds with the stand). The EX700 models do not sport Sony's new monolithic design, which has a seamless front panel (no raised bezel) and a flat base that allows you to tilt the panel. Still, the KDL-52EX700 has an attractive if conservative design, with a gloss-black bezel and a brushed-aluminum accent strip along the bottom of the screen. A pair of down-firing speakers resides on the underside of the panel. The package includes an easy-to-assemble base that has a matching gloss-black finish and a swiveling mechanism. The supplied remote lacks backlighting or dedicated source buttons, and it puts a lot of black buttons against a black background; still, it has a generally intuitive layout with buttons that provide direct access to desired functions: Internet video, aspect-ratio adjustment, i-Manual to pull up the onscreen owner's manual, and an Options button for quick access to picture and sound adjustments, Motionflow, and more. The one thing I'd like to see on the remote is a pull-out keyboard that makes it easier to input text when signing in to Web accounts or searching YouTube content.
The KDL-52EX700 has a generous connection panel, starting with four HDMI inputs that accept both 1080p/60 and 1080p/24 signals. You also get two component video inputs and one PC input, as well as a single RF input to access the internal ATSC and Clear-QAM tuners. Two of the HDMI inputs are located on the side panel, where you'll also find a USB port that supports video, music, and photo playback. (Previous Sony TVs often limited the USB functionality to photo playback only.) The back panel contains an Ethernet port through which you can add the TV to your home network to stream movies, music, and photos from a PC or DLNA-compliant media server. Sony's Renderer feature lets you access media files stored on compatible network devices (like digital cameras and mobile phones) that also support the Renderer function. The network connection also gives you access to the BRAVIA Internet Video platform, which includes both Netflix and Amazon video-on-demand, YouTube, Yahoo video, blip.tv, Wired, myplay music network, Slacker and NPR Radio, and more. The KDL-52EX700 doesn't include the integrated 802.11n card that you'll see on some step-up Sony models, but it does support the add-on UWA-BR100 Wireless LAN adapter ($79.99), which connects to the USB port. The KDL-52EX700 lacks RS-232 and/or IR ports for easy integration into an advanced control system.
Like previous Sony models, this one uses the XrossMediaBar onscreen menu to explore setup options, inputs, and media features. The menu is intuitive, but it can be tedious to navigate when making picture and sound adjustments--which is why it's nice that the remote's Options button provides a more direct path to these controls. As usual, Sony offers a ton of picture adjustments, although a couple of them are oddly placed in the Preferences menu instead of the Picture & Display menu. In Preferences, you can choose between eight Scene Select modes that adjust the image based on content type: Cinema, Sports, Photo, Auto, etc. (I went with the General mode and then customized the image via the Picture Adjustments menu.) The Eco sub-menu includes the ability to enable and set the duration of the Presence Sensor, as well as a Power Saving option that limits panel brightness to reduce energy consumption. Standby and auto shutoff modes are available, and the KDL-52EX700 also has an Energy Saving Switch on the right side panel to cut standby power consumption altogether (this is essentially a hard power on/off button, so you can't turn on the TV, via the remote or otherwise, when the switch is enabled).
In terms of picture adjustments, the KDL-52EX700 has most of the desirable options, including: three picture modes (Custom, Standard, and Vivid); a 10-step adjustable backlight and an ambient sensor that automatically adjusts panel brightness based on room lighting; four color-temperature options and advanced RGB bias and gain controls; noise reduction and MPEG noise reduction; a seven-step gamma control; an auto light limiter that can reduce light output in really bright scenes to cut down on eye strain; and more. Cinemotion is the name of the function that allows the TV to detect the 3:2 cadence that's added to 24-frames-per-second film content to create 60Hz output; the menu includes Off, Auto 1, and Auto 2 options. Auto 2 provides basic 3:2 detection, while Auto 1 uses motion interpolation to create smoother movement with film sources. Sony's Motionflow 120Hz technology can further reduce film judder to produce even smoother movement, and it cuts down on the motion blur that's common to LCD technology. The Motionflow setup menu includes Off, Standard, and High settings. Different combinations of the Cinemotion and Motionflow settings result in a different quality of motion with film sources, which we'll discuss in the Performance section.
The KDL-52EX700 includes four aspect-ratio options: Wide Zoom, Full, H Stretch, and Zoom. This TV lacks a separate native or pixel-for-pixel mode, but you can configure the Full mode to be "Full Pixel" with 1080i/1080p content by making adjustments in the Screen setup menu: To remove overscan, you need to turn off the Auto Display Area function and set the display area to Full Pixel.
The Sound menu includes four sound modes: Standard, Dynamic, Clear Voice, and Custom. In each mode, you can adjust treble, bass, and balance, and the Custom mode allows you to fine-tune the output using a seven-band equalizer. The KDL-52EX700 also has generic surround, sound enhancer, and Steady Sound options, but it lacks big-name audio processing from a company like Dolby or SRS.
This is my first go-round with an edge-lit LED-based LCD. I've reviewed a number of full-array LED models, and I was curious to see how an edge-lit model compares. Naturally, the first thing to evaluate was the TV's black level. The benefit of a full-array LED-based LCD with local dimming is that it allows the TV to turn off portions of the backlight to create deeper blacks without sacrificing light output. This edge-lit model doesn't use any type of local-dimming technology, so we're still dealing with an always-on backlight, just as you get with a traditional CCFL backlight. As a result, the KDL-52EX700's black level, while respectable, is not as deep as I've seen from the best full-array LED models. In DVD and Blu-ray demo scenes from The Bourne Supremacy (Universal Home Video), Signs (Buena Vista Home Entertainment), The Pirates of the Caribbean: The Curse of the Black Pearl (Buena Vista Home Entertainment), and Casino Royale (Sony Pictures Home Entertainment), black portions of the image weren't as dark as I've seen elsewhere; however, the overall black level was deep enough to provide a solid foundation, resulting in an image that still had nice saturation in a darker viewing environment. Even at the minimum backlight setting, this TV is fairly bright, which contributes to the slightly higher black level but helps the overall contrast. The KDL-52EX700's good light output makes it especially well suited for HDTV shows and sports programming, which pop off the screen. Brighter DVD/Blu-ray scenes also fared well.
In the color realm, the KDL-52EX700 served up a generally natural-looking image without demanding a lot of adjustment. The Warm 2 color temperature is the closest to reference 6500K and is definitely the warmest of the available presets. Still, it seems to veer slightly cool, especially with darker signals. The nighttime skies of The Corpse Bride (Buena Vista Home Entertainment) had a slightly bluish tone--it wasn't excessive, and frankly it added a bit of pop to whites that the average user will likely prefer. Skintones looked natural, without too much red push. For those who desire a more accurate color temperature across the board, advanced white-balance controls are available to dial in a warmer color palette. The TV's color points also look fairly accurate--with the exception of green, which seems slightly exaggerated. The one high-end video adjustment that this TV lacks is the ability to precisely tweak each color point, and I would've liked the option to adjust green more precisely. Nevertheless, I was generally satisfied with the color: It looked rich and natural, without being cartoonish.
