When looking at processing, three main factors are important: sharpness processing when upscaling a low-resolution signal, low-quality content smoothing, and HDR native gradient handling. A TV's upscaling and sharpness processing is especially important if you're watching low-resolution content from a physical player that doesn't have its own upscaling features, like a cable box or an older DVD player. Good upscaling will accurately scale lower resolutions to the higher-resolution pixel count of the screen, maintaining fine details and delivering a sharp, clear image with no noticeable defects. Poor upscaling and sharpness processing will do a bad job of translating this detail, rendering the image blurry or overly sharp.
