    Detailed Test Results

    HD PICTURE QUALITY HD picture quality was Very Good, overall. Reproduction of fine HD image detail was Excellent, however, image detail was very exaggerated and made images appear less natural, despite our attempts to minimize this with the sharpness control. Color accuracy was Excellent, so colors, especially flesh tones, look very natural and lifelike. Very Good contrast—the difference between the darkest blacks and brightest whites—gave images convincing depth and dimension. But black levels were merely OK, and maintained some contrast in darker scenes, but fell short of the better TVs. The quality appeared worse as we viewed from the sides—see our Viewing Angle results, below. Image brightness was Very Good (with the backlight control turned up), so the picture was well suited for a brighter room—a lower setting is recommended for a dimmer viewing environment. Its reproduction of smooth edges on image content for "up-converted" HD-to-UHD images was Very Good with minimal "jaggies" (jagged edges). Deinterlacing of 1080i video, and film-mode detection of 1080i film-based content, were both Excellent.

    4K UHD PICTURE QUALITY Overall 4K UHD picture quality was Very Good, overall. 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's lack of high peak brightness capability (by HDR standards) limited its ability to show 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. In HDR mode this TV only allowed us to optimize the Brightness and Gamma picture settings—all other settings were as they were for the standard-dynamic range (SDR) HD picture. 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, but we noted some loss of detail within the highlights of the brightest areas. Brightly colored objects remained nicely saturated.

    VIEWING ANGLE This Sony model has a narrow viewing angle overall, below-average performance among TVs. Only those seated directly in front of the screen will see the best picture quality. We examined the image quality at various viewing angles—its image quality notably decreased as we moved away from the center position. In our tests, the picture did show some slight dimming from the sides, but not to a distracting degree. When we viewed the TV from the sides image quality degraded significantly. The picture showed a moderate loss of color, so flesh tones looked a bit washed out. Black levels visibly brightened, and reduced the contrast especially on dark scenes. Lastly, we viewed the image from above and below center screen, and noticed Good vertical viewing angle performance, with only slight changes in color, contrast, and black level.
