PICTURE QUALITY It did an excellent job displaying the finest detail. Color accuracy was excellent, so colors looked very natural and lifelike. Contrast--the difference between the darkest blacks and brightest whites--was good, so images had depth and dimension, typical of most models we test. The brightness level was good, making it a suitable choice for most rooms. Black levels are excellent, with help from LG's LED Local Dimming, a local dimming feature, delivering very deep blacks that enhance contrast in dark scenes. In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the model did a very good job producing a smooth transition without distinct, coarse bands. There was slight display non-uniformity that created brighter cloudy areas most noticeable on very dark scenes (or in the black bars of a letterboxed movie). We routinely see this issue with LCDs and severity can vary from model to model. Check your model and see if you find it a problem. The deinterlacing and film mode operations were excellent on HD content; there was little or no trace of jaggies on the edges of objects for video and film-based 1080i video content, such as from cable.
VIEWING ANGLE This LG has a wide viewing angle overall, better than that of most TVs. It will provide the same picture quality, with fewer problems than most TVs, for typical viewing conditions -- say, if your family is seated across a long sectional or in chairs off to the sides. With brighter scenes, this model did a fine job maintaining accurate colors and contrast as we viewed it from the sides. The picture did show some dimming from the sides but not to any point we found distracting. With dark scenes this model didn't fare quite as well. When viewed from the sides, the depth of black levels varied depending on the vertical position of the viewer's head. As we moved closer to the screen this limitation became even more apparent, especially if seated on the floor looking upward where black levels brightened significantly. This model's wide horizontal viewing angle is best appreciated when viewed at eye level to the screen.
ULTRA HD PERFORMANCE Overall, excellent. This LG UHD TV delivers 4K picture detail, along with very good HD-to-UHD upconversion. All native 4K content we played on this model, including movies and test videos was presented in full detail with excellent image fidelity when played back via the TV's HDMI input. Though our 4K test patterns showed some slight loss of the finest detail, we couldn't detect this on normal 4K video content. This TV does support the playback of HDR (high dynamic range) content through both its HDMI and USB inputs, however we didn't find its capabilities to be very effective on our HDR test videos. It also supports video streaming of 4K programs via both Netflix and YouTube (among other sources), and again, images were finely detailed. Using the TV's USB port, we were able to play back 4K videos stored on a flash drive encoded in the HEVC, MP4, and VP9 formats. High resolution photos looked clean with no added image processing to mar quality, taking full advantage of the display's extra detail. With regular HD content, the TV's HD-to-UHD up-conversion processing was very good, with edges along diagonals of image content showing very slight jaggies, just short of the best we've seen. All three of the TV's HDMI inputs comply with the latest HDCP 2.2 and HDMI 2.0 specifications for both copy protection and 4K video play back at 60Hz, a requirement for compatibility with 4K movie play back devices such as a 4K Blu-ray player.
MOTION BLUR This LG TV has only fair motion performance, with significant blurring on our motion tests. This model does not include a blur reduction feature. The visibility of blurring on typical program content is often subtle and may not bother most people, but keen-eyed viewers may detect some loss of texture and detail on scenes with movement.
SCREEN REFLECTIVITY Though not as mirror-like as on some models, this screen surface is glossy and therefore susceptible to reflections from a nearby lamp or window. The screen is dark so it does a good job reducing glare from ambient light and maintains contrast even in a bright room.
SOUND QUALITY This model has good sound quality; about average among the models we've tested. When watching a movie blockbuster, a concert, or TV show, it delivers decent performance but falls short of the better performers. With movies, dialog was generally clear and natural sounding, though a bit muffled, and remained well balanced with respect to background music and other sounds. Bass was deep, providing satisfying fullness to the sound but it was a bit boomy. Treble was nicely detailed, while the overall sound was a bit closed in. The speakers produced a good volume -- so this model should play sufficiently loud in typical room environments, and sound quality degraded at the highest volume settings. Also, at higher volume, dynamic compression kept the sound from distorting, but also limited the clarity of peaks in loudness, which was distracting. Most people would find this sound quality acceptable.
EASE OF USE Overall, it was OK to setup and fairly easy to do routine things. The dark labeling of the connectors on the TV console is very difficult to read. On first power up there is an on-screen guide that helps you through setting up the TV. The remote's major function buttons were sufficiently large and have high-contrast labeling, making them easier to see and navigate.
STAND ASSEMBLY The TV's base does not come pre-attached, so some assembly is required. Mounting the support stand to the TV is straightforward, though the stand requires the assembly of one part before mounting. The TV's stand extends to the far ends of the display, which means the table top you'll be setting the TV on will need to be at least as wide as the display itself.
INTERNET FEATURES This TV provides advanced Internet capabilities via its "WebOS 3.0" portal with access to a library of applications, and a full Web browser. Movie streaming services include: Netflix, Amazon, Hulu Plus, Vudu, YouTube.
CONNECTIONS This model has three HDMI inputs--one supports MHL (Mobile High-definition Link), a component/composite shared input (which means you can only use one type or the other at a time). It also has two USB ports, an optical digital audio out, an Ethernet port. Wireless connectivity is built-in. DLNA: accesses files within your home network. Casting: control the TV from a smartphone that has the suitable app installed. Screen mirroring: the image on your smartphone or other compatible device can also appear on the TV. Note: HDMI and other cable connections made to the rear-facing panel will protrude beyond the panel's slim depth.
INCLUDED IN THE BOX A printed user manual. A quick start guide. An electronic manual in the TV's menu. A remote control with batteries. A detachable power cord.
ABOUT FIRMWARE VERSION: Our test results and picture settings are valid for the version of firmware indicated. If your TV's firmware differs from the one shown you either have an older or a newer version. Manufacturers may periodically upgrade the TV's firmware to enhance operation, fix bugs, or add features. Firmware upgrades may be downloadable directly to your TV via a wired or wireless network (if internet capable), or USB port, depending on your TV's capability. You can check your TV's firmware version, or upgrade to the latest firmware by pressing the menu, or home button on your remote and navigating to the appropriate submenu, typically under settings. Consult the user manual or manufacturer's website if further guidance is needed.
