"Contrary to popular belief, the "sharpness" setting on your TV doesn't affect the actual sharpness of the displayed image. True sharpness is determined by factors such as screen resolution, source material resolution, and contrast. Instead, the sharpness setting alters the artificial edge enhancement -- a processor-driven adjustment that can introduce unwanted noise and, ironically, distort details in the image. While it may not be necessary to reduce sharpness to zero, it's generally recommended to turn it down significantly."
"An important setting to consider adjusting is Motion Smoothing, a frame interpolation feature created to reduce the blurring effect noticeable during fast-paced sequences. This feature aims to reconcile discrepancies between movie frame rates (usually 24 frames per second) and the TV's frame rate. When scenes filmed at 24fps are played on a higher frame rate TV, watchers might notice an effect known as "judder.""
Television picture quality depends on settings like sharpness, motion smoothing, resolution, source material, and contrast. The sharpness control adjusts artificial edge enhancement rather than actual image detail, which can introduce noise and distort fine details; lowering sharpness to about five to ten percent often yields a more natural image. Motion Smoothing uses frame interpolation to reduce judder when converting 24fps content to higher TV frame rates, but it can create an unnatural look during fast or cinematic scenes. Viewers should experiment with these settings to find a balanced, noise-free image that matches personal preference and source material.
