![]() All four of the TV's HDMI inputs comply with the latest HDMI 2.0 and HDCP 2.2 specifications that support play back for 4K video at 60Hz, and copy protection, a requirement for compatibility with emerging 4K movie play back devices such as a 4K Blu-ray player. With regular HD content, the TV's HD-to-UHD up-conversion processing fell short, with only good performance revealing some visible jaggies along the edges of diagonals when playing HD content. High resolution photos were displayed in 4K detail, taking full advantage of UHD's extra resolution. Using the TV's USB port, we were able to play back 4K videos stored on a flash drive encoded in the HEVC, MP4, and VP9 formats. Using the TV's USB port, we were able to play back 4K videos stored on a flash drive which were encoded in the HEVC, MP4, and VP9 test file formats. No picture controls other than a picture mode selection are available while streaming. If you plan on streaming 4K and you're not crazy about this effect, this could be a deal breaker. Also referred to as a "soap-opera-effect," motion smoothing removes the natural judder (or jerky motion) that is normal for films shot at 24Hz. This model also supports video streaming of 4K programs via both Netflix and YouTube (among other emerging sources), with generally finely detailed 4K images but we also noted that a motion smoothing feature was active which could not be turned off. All native 4K content we played on this model, including movies and test videos from our Sony FMPX10 player, was presented in full 4K detail with excellent fidelity when played back via the TV's HDMI input. ULTRA HD PERFORMANCE This Sharp UHD TV delivers excellent 4K picture detail, but only decent HD-to-UHD upconversion and streaming performance. The picture showed minimal change in color, contrast, and black level. When viewing the image from above or below eye level to the screen, the vertical viewing angle was very good. ![]() Black levels visibly brightened, reducing contrast. When we moved off to the sides the horizontal viewing angle was fair the picture showed a moderate loss of color so flesh tones looked washed out, along with a moderate color shift. If your family is seated in chairs off to the sides of the TV, they will see increasing degradation of image quality the farther they sit from center. Only those seated directly in front of the screen will see the best picture quality. ![]() VIEWING ANGLE This Sharp has a narrow viewing angle overall, below-average performance among LCD sets on this attribute. 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. Check your model for this issue, and if present, see if you find it distracting. We routinely see this issue with LCDs and severity can vary from TV to TV. There was slight display nonuniformity that created brighter cloudy areas most noticeable on very dark scenes (or in the black bars of a letterboxed movie). In scenes with subtly shaded light-to-dark areas, such as a sky during sunset, the TV did an excellent job producing a smooth transition without distinct, coarse bands. (assumes the image is viewed directly from front and center see viewing angle comments) Images had some enhancement that slightly diminished the realism of people and objects. Turning on Sharp's "AquoDimming," a local dimming feature, seems to have no visible impact on black level so we left the feature off. Black levels were generally good, though not as dark as better performers on the darkest scenes. The brightness level was good, making it a suitable choice for most rooms. Contrast-the difference between the darkest blacks and brightest whites-was good, so images had depth and dimension, typical of most models we test. Color accuracy was acceptable, but below that of most sets with the image color tending toward a teal, along with a cooler color temperature. It generally did an fine job reproducing HD image detail, but quality was diminished by very aggressive oversharpening and edge enhancement which ultimately marred image quality. PICTURE QUALITY This model's high-definition picture quality, though good, was below that of most other sets.
