HD PICTURE QUALITY. HD picture quality was very good. It did an excellent job displaying the finest detail of HD content. Color accuracy was excellent, so colors, especially flesh tones, looked very natural and lifelike. Contrast--the difference between the darkest blacks and brightest whites--was good, so images had depth and dimension. Depth of black level was below average, with darker scenes in particular looking hazy, with little contrast. This was one of the brighter models we've tested (with the backlight control turned up), so the picture remains quite viewable in a very sunny room. A lower backlight setting is recommended for a dimmer viewing environment. 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. 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 Sony 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. 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.
ULTRA HD PERFORMANCE. Overall UHD performance is very good, but HD-to-UHD upconversion falls short. All native 4K content (non HDR) we played on this model, including movies and test videos, was presented in full 4K detail with excellent fidelity when played back via the TV's HDMI input. Via the USB port, high-resolution photos were displayed in full 4K detail. With regular HD content, the TV's HD-to-UHD up-conversion processing fell short, revealing some visible jaggies along the edges of diagonals when playing HD content.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance is limited. The display had decent brightness capability (by HDR standards) showing some improvement over basic 4K performance on our HDR test videos, while revealing little contrast between moderately bright and very bright highlights within a scene. It did a good job reproducing a greater range of nuanced shadow detail from black to white, with no obvious banding on areas of the image that have subtle shade variations, but some loss of near-white shadow detail in the brightest areas was noted. Very bright colored objects remained nicely saturated.
MOTION BLUR. This Sony TV has very good motion performance, with minimal blurring on our motion tests, thanks to Sony's "Motionflow". This feature is designed to reduce motion blur, a shortcoming of most displays. Although this TV includes a "Clearness" setting that was slightly effective at further reducing motion blur, it limited the brightness of the image and also added some flicker to the picture, so we left the feature off.
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. It does a good job reducing glare from ambient light and maintains contrast in a brighter room environment.
SOUND QUALITY. This model has very good sound quality, better than most models we've tested. Whether you're watching a blockbuster movie, a concert, or TV show, it is able to deliver a satisfying listening experience. Bass was adequate, which added some fullness to the sound, and treble was nicely detailed, while the overall sound was a bit closed in. The speakers produced a good volume range so this model should play sufficiently loud in typical room environments and without obvious distortion. Also, at higher volume, dynamic compression kept the sound from distorting but also limited the clarity of peaks in loudness, which can be a bit distracting on some audio content. Unlike most of our tested models, this model's sound should satisfy the more discerning listeners, so an external sound bar is optional.
EASE OF USE. On first power up there is an on-screen guide that helps you through setting up the TV. Sony's advanced remote offers a traditional button keypad with high contrast labeling that remains fairly readable in a dimly lit environment. It has a dedicated button to access Google Assistant via the remote's built-in microphone. It also provides direct button access to Netflix and Google Play streaming services. The TV's stand is 45 inches wide.
INTERNET FEATURES. This TV provides basic Internet functionality with a limited selection of applications via its "Android TV" portal with access to a library of applications. Movie streaming services include Netflix, YouTube, Amazon Prime Video, Hulu, HBO Go and HBO Now. Includes built-in Google Assistant, which allows you to use natural speech to ask questions, launch applications, and search programming. Also provides support for Amazon Alexa.
CONNECTIONS. This model has four HDMI inputs-- one supports ARC (Audio Return Channel), one "component/composite shared" input (which means you can only use one type or the other at a time). It also has three USB ports, an optical digital audio out, a headphone out, an Ethernet port, WiFi wireless networking; DLNA, to access files within your home network; 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. 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. One IR Extender.
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 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.
