PICTURE QUALITY It did a very good job displaying fine detail. Color accuracy was very good, with images generally looking natural. 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 were only fair with darker areas of the image looking unnaturally illuminated. With local dimming enabled, black levels are good, delivering decent blacks. 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. Film mode operation for HD film-based content was only good, as was deinterlacing performance. There were visible jaggies along the edges of objects during motion scenes on movies, and jaggies were also visible when converting 1080i video content to the display's native resolution.
VIEWING ANGLE This Vizio 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. When we viewed the TV from the sides the image quality showed some loss. When viewing the image from above or below eye level to the screen, the vertical viewing angle was excellent. The picture showed no change in color, contrast, and black level.
ULTRA HD PERFORMANCE Overall, falls short. 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, was presented in 4K detail when played back via the TV's HDMI input, but we did note some reduction of fine detail such as on skin texture when compared to our 4K reference TV, possibly due to some noise reduction processing, but this was quite subtle and shouldn't be a concern. This model also supports video streaming of 4K programs via Netflix and again image detail was generally fine but texture was slightly compromised as noted previously, and we noted a touch of added edge enhancement. We could not access 4K content via YouTube. 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 ,MP4 or VP9 format. 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, but 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 4K movie play back devices such as a 4K Blu-ray player.
MOTION BLUR This Vizio TV has good motion performance, with some blurring on our motion tests. Though this model includes Vizio's Clear Action, a feature designed to reduce motion blur, we found it was ineffective.
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 fair sound quality with below average performance. It's acceptable for typical programming, but shortcomings become obvious with movie soundtracks and music. With movies, dialog was generally clear and natural sounding, though a bit muffled, and background music and other sounds were slightly recessed. Bass was lacking. Treble was nicely detailed, but was somewhat closed in. The speakers produced a good volume -- so this model should play sufficiently loud in typical room environments, and was made worse by the fact that sound quality degraded at high volumes a little audible distortion . Also, at higher volumes, dynamic compression kept the sound from distorting, but also limited the clarity of peaks in loudness, which was distracting on some audio content. If sound quality matters to you, you might want to add a soundbar or other external speaker system.
EASE OF USE Overall, it was fairly easy to setup and OK to do routine things. On first power up there is an on-screen guide that helps you through setting up the TV.
STAND ASSEMBLY The TV's base does not come pre-attached, so some assembly is required. 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 "Vizio Internet Apps Plus" portal with access to a library of applications. Movie streaming services include: Netflix, Amazon, Hulu Plus, Vudu, YouTube. [Source not found]. [Source not found].
CONNECTIONS This model has five HDMI inputs--one supports a Mobile High-definition Link (MHL), one component input, and one composite input, a component/composite shared input (which means you can only use one type or the other at a time). It also has one USB port, 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.
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 A quick start guide. An electronic manual in the TV's menu. A remote control with batteries. A detachable power cord. No printed manual is included.
ABOUT ULTRA HD TESTING: We test UHD picture quality using 4K movies, videos, photos, and test patterns to confirm these displays deliver performance to this format's full potential. We check the TV's ability to reproduce 4K image detail, as well as high dynamic range (HDR) for TVs that support this capability. Image quality is tested using a 4K movie player connected to the TV's HDMI input, as well as from files stored on flash drive plugged into the TV's USB port. We also check the quality of 4K streaming from Netflix or YouTube (if the service is supported by the TV), and how well the TV can upscale HD movies to the display's higher UHD resolution while keeping artifacts such as "jaggies" along the edges of image content to a minimum. The best UHD TVs, and HDTVs, present high fidelity images that reveal the full quality of the best source content without degradation.
ABOUT CR's TV VIEWING CONDITIONS: Our picture settings are optimized for a dimmer home viewing environment. If the settings we recommend don't suit your taste or your environment, use the picture controls to achieve an image you consider "just right."
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.
