    Detailed Test Results

    PICTURE QUALITY Picture quality was excellent. Reproduction of fine image detail was excellent. Color accuracy was very good, with flesh tones in particular, looking natural. Excellent contrast—the difference between the darkest blacks and brightest whites—in dark scenes gave images great depth and dimension. Black levels were excellent, and delivered very deep blacks that enhanced contrast in dark scenes. Image brightness was very good (with the brighness at max), 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 generally excellent and free of "jaggies" (jagged edges). Deinterlacing of 1080i video was excellent. Its frame-rate compensation for 1080i film-based content was excellent.

    HIGH DYNAMIC RANGE (HDR) PERFORMANCE HDR performance had limited effectiveness. In our tests, the display's high peak brightness capability was very good, and helped reproduce the realism of our HDR 4K content. It revealed somewhat-limited 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. 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. We noted some loss of detail within the highlights of the brightest areas.

    VIEWING ANGLE This display has unlimited viewing angle. This helps make the TV a good choice for large group viewing. We saw excellent consistency at various viewing angles, the contrast and black-level were largely unchanging. When we viewed the TV from the sides the picture showed a slight shift in color tone, but overall color remained consistent with no degradation in overall image quality. Lastly, we viewed the image from above and below center screen, and saw excellent vertical viewing angle performance, with no significant changes in color, contrast, and black level.

    MOTION BLUR In our motion tests, this LG OLED had generally excellent motion performance, with only slight blurring.

    SOUND QUALITY We got very good sound quality, better than most models we've tested. Whether you're watching a blockbuster movie, a concert, or TV show, it can deliver a satisfying listening experience. In our listening evaluations, we found the bass (low frequency sound) was moderately deep and provided some sense of fullness and mostly well defined. Treble (high frequency sound) was very good. The treble was generally neutral. This TV should be OK if the room isn't too noisy—we found the speakers could produce a good volume level. Overall, unlike most of our tested models its sound should satisfy the more discerning listeners, so give this a listen before opting for an external sound bar.
