HD PICTURE QUALITY. HD picture quality was Excellent. Reproduction of fine HD image detail was Excellent. Color accuracy was Excellent, so colors, especially flesh tones, look very natural and lifelike. Excellent contrast—the difference between the darkest blacks and brightest whites—gave images great depth and dimension. Black levels were Excellent, and delivered very deep blacks that enhanced contrast in dark scenes. This was among the brightest models we've tested (with the Luminance control turned up), so the picture was well suited for a very sunny room—a lower setting is recommended for a dimmer viewing environment. There was notable display non-uniformity in our test sample—it appeared as brighter cloudy areas which were most visible on very dark scenes (or in the black bars of a letterboxed movie)—the severity can vary from model to model. Its reproduction of smooth edges on image content for "up-converted" HD-to-UHD images fell short with some visible "jaggies" (jagged edges); deinterlacing of 1080i video was Excellent; and film mode detection from 1080i content was Excellent.
4K UHD PICTURE QUALITY. Overall 4K UHD picture quality was Excellent. In our UHD testing, we played native-4K movies and test videos (non HDR) thru the TV's HDMI input, and found their image detail was all there. For color, contrast and black level, the TV performed similarly to its HD picture quality.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance had limited effectiveness. In our tests, the display showed Good peak brightness capability (by HDR standards) and did a fine job displaying the benefits of our HDR 4K content. It could not reveal much contrast between the moderately bright and very bright highlights, while the brightness levels in the mid-to-lower tones, like those in an indoor scene, were preserved. It did a good job reproducing a greater range of nuanced shadow detail, from black to white, with no obvious banding within the gradually shaded areas. There was no visible loss of detail within the highlights of the brightest areas. Brightly colored objects remained nicely saturated.
VIEWING ANGLE. This display has very wide viewing angle, better than most TVs we've tested. This helps make the TV a good choice for large group viewing. Our examination at various viewing angles indicated Excellent consistency. Contrast and depth of black level were largely unchanging from any viewing position. When we viewed the TV from the sides the picture showed a slight shift in color tone, but overall color remained consistent with no degradation in overall image quality. We viewed the image from above and below center screen, and saw Excellent vertical viewing angle performance, with no significant changes in color, contrast, and black level.
MOTION BLUR. In our motion tests, this Vizio TV had Very Good motion performance, with minimal blurring thanks to Vizio's "Motion Blur Reduction." This feature is designed to reduce motion blur, a shortcoming of most displays. Although this TV also includes a "Clear Action" setting that we found was slightly effective at reducing motion blur, it limited the brightness of the image and so we left the feature off.
SOUND QUALITY. We got Very Good sound quality, better than most models we've tested. Whether you're watching a blockbuster movie, a concert, or TV show, it can to deliver a satisfying listening experience. In our listening evaluations, we found the bass (low frequencies) was moderately deep and provided some sense of fullness but lacked some definition. Treble (high frequencies) was satisfactory. The overall sound was a bit closed in. This TV should be OK in rooms large or small, noisy or quiet—we found the speakers could play at a fairly loud volume level, but quality did degrade at the highest settings and slight cabinet resonance. Unlike most of our tested models its sound should satisfy the more discerning listeners, so give this a listen before opting for an external sound bar.
EASE OF USE. Consider the TV's stand is 22 inches wide when choosing a table top to place it on. On first power up, an on-screen guide appeared—which you could choose to follow when setting up the TV. The remote controls the TV via an IR light beam which must be pointed at the TV. It has a full number keypad for entering channel numbers. It includes all the buttons we typically expect: power, channel up/down, volume control, mute, source input, menu, and exit. It also has dedicated buttons for streaming Vudu, Netflix, Prime Video, Xumo, Hulu, Redbox, and Watch Free (Pluto TV).
INTERNET FEATURES. This TV provides certain access to the internet with access to limited library of applications from the Google Play Store/ App Store. Its movie streaming services include Netflix, YouTube, Amazon Prime Video, Hulu, Disney and Apple TV. More so, Netflix, YouTube, Amazon Prime Video, Disney and Apple TV can be streamed in 4K UHD. Claimed support for external voice assistants (not built in to the TV) include Amazon Alexa, Google Assistant, and Siri Homekit.
CONNECTIONS. This model has four HDMI inputs (one supports eARC, enhanced audio return channel). It also has one USB port, an optical digital audio out, an Ethernet port, WiFi wireless networking; Casting, which allows you to send streaming content from your mobile device to the TV via your home network; Screen mirroring, where the image on your smartphone or other compatible device can also appear on the TV; and AirPlay, for sharing videos, photos, music, and more from Apple devices to the TV.
WHAT'S INCLUDED. You get with this TV: a quick start guide, an electronic user guide via the TV's menu, a remote control with batteries, and a detachable power cord. No printed manual is included.
ABOUT UHD TESTING: Ultra-high definition "UHD" can refer to both the TV and program content. While the UHD industry standard includes 4K and 8K, most UHD TVs and UHD content at this time are 4K. A 4K UHD image is presented as 3840 x 2160 pixels—four times the pixel-count of HD. We test UHD TV picture quality using 4K UHD movies, videos, photos, and test patterns to confirm these displays deliver performance to this format's full potential. We examine the TV's ability to reproduce 4K UHD image detail, as well as high dynamic range (HDR)—for TVs that support this capability. Image quality is tested using a UHD movie player connected to the TV's HDMI input, and from files stored on USB flash drive. We also check 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.
