HD PICTURE QUALITY HD picture quality was Very Good, overall. Reproduction of fine HD image detail was Excellent, though image detail was very exaggerated and made images appear less natural, despite our attempts to minimize this with the sharpness control. We also noted some added edge enhancement processing which makes the image look a little less realistic. 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. However, black levels were 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 Good (with the backlight control turned up), making it a suitable choice for all but the sunniest rooms. 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 was Very Good with minimal "jaggies" (jagged edges). Deinterlacing of 1080i video, and film mode detection from 1080i 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 very 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 slightly low. 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 Samsung 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 brightened significantly, and made dark scenes look hazy. 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.
