Television quality refers to the overall fidelity of video and audio delivered by television systems. It depends on source content, transmission, display capability, and viewing conditions, as well as viewer perception.

Image resolution affects perceived sharpness. Common categories include SD, HD, 1080p, 4K (2160p), and 8K. Higher resolution can improve detail but requires adequate bandwidth and a capable display.

Color and contrast describe color accuracy and dynamic range. Color spaces such as Rec. 709 and Rec. 2020, and formats like SDR and HDR, influence realism. HDR formats include HDR10, HDR10+, Dolby Vision, and HLG.

Motion handling and frame rate impact smoothness. Higher frame rates and quality processing reduce blur, but can add artifacts or input lag in interactive contexts.

Signal quality and processing involve compression, bitrate, and upscaling. Encoders (MPEG-2/4, H.264/AVC, HEVC, AV1) save bandwidth. Upscaling and color conversion affect the final image.

Calibration and environment matter. Proper calibration and accurate color management reveal display capability, while ambient light and seating distance affect perceived contrast and detail.

Assessment blends objective metrics and user experience. While metrics like VMAF or PSNR exist, television quality is ultimately determined by the balance of resolution, color, brightness, contrast, motion, and sound, aligned with content and expectations.
