PICTURE QUALITY This model had excellent high-definition picture quality. It did an excellent job displaying the finest detail, though we did detect some added edge enhancement applied to the image. Color accuracy was very good with images generally looking natural, though color temperature was slightly on the cool side, lending images a bluish tone. 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 very good delivering fairly deep blacks due to Vizio's effective "Active LED Zones," a local dimming feature designed to give greater depth and contrast to dark scenes. Any unwanted illumination side effects often introduced by such a feature were minimal so we left the feature on. With the feature off, black levels were still acceptable. (see "viewing angle" comments for other limitations on black level quality.) In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the TV did a very good job producing a smooth transition without distinct, coarse bands. Film mode operation for HD film-based content was excellent, with no visible jaggies along the edges of objects during motion scenes. Deinterlacing on the other hand was only good, with some jaggies visible when converting 1080i video content, such as from cable, to the display's native resolution.
VIEWING ANGLE This Vizio has a moderate viewing angle overall, decent, but not quite as good as the better-performing LCD sets we've tested. The optimal seating position for best picture quality is directly in front of the TV. If your family is seated in chairs off to the side of the TV, they'll see decent but compromised image quality.
When we moved off to the sides the horizontal viewing angle showed a strong loss of color so flesh tones looked very washed out, along with a slight color shift. Black levels brightened slightly, reducing contrast a bit on dark scenes. When viewing the image from above or below eye level to the screen, the vertical viewing angle was very good. The picture showed minimal change in color, contrast, and black level.
ULTRA HD PERFORMANCE This Vizio UHD TV delivers very good 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 from our Sony FMPX10 player, showed very good detail when played back via the TV's HDMI input, just short of the better performers. We saw some reduction of fine detail such as on skin texture when compared to our 4K reference TV, possibly due to some noise reduction processing. The most recent firmware update seems to have addressed a bug we consistently noted on prior M-series UHD models where the TV's motion smoothing feature defaulted to active after the TV is turned off. With this update, native movie 24 Hz film judder has been restored, and the motion smoothing feature can be invoked in the menu as desired. This model also supports video streaming of 4K programs via both Netflix and YouTube (among other emerging sources), and again image detail was generally fine but again texture was compromised as noted previously. Using the TV's USB port, we were not able to play back 4K videos stored on a flash drive which were encoded in the HEVC format, or our MP4 or VP9 test files. With photo play back, high-resolution images were unfortunately downscaled to lower 1080p resolution, not taking advantage of the display's detail potential. With regular HD content, the TV's HD-to-UHD upconversion processing was very good, with edges along diagonals of image content showing very slight jaggies, just short of the best we've seen. Three of the TV's five HDMI inputs comply with the latest HDCP 2.2 copy protection specification, and only one of those three is HDMI 2.0 compatible and able to support play back of 4K video at 60Hz. These specifications are required for compatibility with emerging 4K movie play back devices such as a 4K Blu-ray player.
MOTION BLUR This Vizio TV has very good motion performance, with minimal blurring on our motion tests, thanks to Vizio's Clear Action. This feature is designed to reduce motion blur, a shortcoming of most LCD TVs. With the feature turned off, motion performance was only fair, with significant blurring on our motion tests.
SCREEN REFLECTIVITY Though not as mirror-like as on some LCDs, 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 TV has good sound quality; about average among the TVs 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, though a bit muffled, while remaining well balanced with respect to background music and other sounds. Bass extension was decent, though a tad boomy, which added some fullness to the sound, and treble was nicely detailed, while the overall sound was on the bright side, and a bit closed in. The speakers can play to fairly loud volume levels without obvious distortion, a plus if you'll be using this set in a larger room or noisy environment. Most will find this sound quality acceptable.
EASE OF USE Overall, we found the set was easy to use for the most part. Setting up the TV for the first time was very easy, as was access to features and controls you'll probably adjust only once. Ease of access to features you typically use more often was good. Also, the remote is satisfactory, and the on-screen menu is easy to navigate.
It lacks a dedicated menu button on the television console, so you can't access the menu if you lose the remote. The full QWERTY keyboard on the remote makes it easier to enter text data.
STAND ASSEMBLY Mounting the support stand to the TV is straightforward. 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 capability. Features include access to a library of applications via "Yahoo Smart TV App Store
CONNECTIONS This TV includes five HDMI inputs, one shared connection between the component and composite inputs (which means you can only use one type or the other at a time), optical digital audio out, one USB port, an Ethernet port, and Wi-Fi. Wireless connectivity includes: DLNA network file sharing. The cable connections on the rear panel are recessed with side or bottom-facing ports, so wires don't protrude beyond the display's depth.
INCLUDED IN THE BOX The TV comes with: an electronic user manual accessible via the TV's menu (no printed manual is included), a quick start guide, and a remote with batteries. 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 of firmware. 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), USB port, or memory card, depending on your TV's capability. You can check your TV's firmware version, or upgrade to the latest firmware by pressing the menu 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.
