HD PICTURE QUALITY. HD picture quality was excellent. It did an excellent job displaying the finest detail of HD content. 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 Sony's "Auto Local Dimming" feature, delivering very deep blacks that enhance contrast in dark scenes (though quality does degrade as you move to the sides, and undesirable illumination effects from local-dimming become more apparent). 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 notable display non-uniformity that created brighter cloudy areas, most visible 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 moderate viewing angle overall, decent, but not quite as good as the better-performing TVs we've tested. The optimal seating position for best picture quality is directly in front of this model. When we viewed the TV from the sides, image quality got worse. The picture showed a moderate loss of color, so flesh tones looked a bit washed out, along with a slight color shift. Black levels visibly brightened, reducing contrast especially 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. Overall UHD performance was excellent but HD-to-UHD upconversion fell 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. This TV can stream 4K programs from Netflix and YouTube. Images were clean and finely detailed. High-resolution photos were displayed in full 4K detail.
HIGH DYNAMIC RANGE (HDR) PERFORMANCE. HDR performance was very effective. The display's very high brightness capability helped enhance the realism of our 4K HDR test videos, while revealing excellent 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 visible loss of near-white shadow detail in the brightest areas. Bright, colored objects remained nicely saturated, and an extended range of color capability was apparent from our test patterns. NOTE: To see HDR video from a 4K Blu-ray player (or other HDR-capable play back device), it must be connected to HDMI 2 or HDMI 3.
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 LCD displays.
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 movie blockbuster, a concert, or TV show, it is able to deliver a satisfying listening experience. Bass was deep, providing satisfying fullness to the sound, and treble was nicely detailed. 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 that remains readable in a dimly lit environment, though buttons are not backlit. It provides direct button access to Netflix and Google Play streaming services, and the built-in microphone allows the user to search the internet via voice commands.
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.
CONNECTIONS. This model has four HDMI inputs-- one supports ARC (Audio Return Channel), one composite input, and 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. 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. One IR Extender. No printed manual is included. Large power brick.
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.
