HD PICTURE QUALITY HD picture quality fell short, overall. Reproduction of fine HD image detail was Excellent. Color accuracy was Excellent, so colors, especially flesh tones, look very natural and lifelike. However, contrast—the difference between the darkest blacks and brightest whites—was Good, so images had some depth, but it was not the best. Black levels were overly bright, unfortunately, worse than many 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 was generally Excellent and free of "jaggies" (jagged edges), whether for "up-converted" HD-to-UHD images, deinterlacing of 1080i video, or film mode detection from 1080i content.
4K UHD PICTURE QUALITY Overall 4K UHD picture quality was decent, 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 was ineffective. In our tests, the display did not have the peak brightness capability necessary (by HDR standards) to reproduce the extended contrast on our HDR content.
VIEWING ANGLE This LG 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 moderate dimming from the sides. 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. 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.
