High-Definition Television (HDTV) picture quality and video playback

    When a video in SD quality is being scaled up and played back, the quality will look poor, even on an HDTV. A video must have HD quality to be played back at high quality on an HDTV. A video with SD quality cannot be converted to HD quality or displayed in SD resolution without the content being stretched. However, by adjusting the Sharpness and Picture Mode of the TV, the quality can be improved. For model-specific information about adjusting the Sharpness or Picture Mode options, check the specifications or supplied operations guide.

    When viewing a video that is not HD quality via an HDTV:

    When a DVD (720 x 480) or other video with SD quality is viewed on an HDTV (1920 x 1080), upscaling the video to something resembling 1920 x 1080 will cause the quality to look poor.

    When viewing a broadcast:
    Even when a TV program is broadcast in HD quality, the transmission may have been upscaled from SD quality (e.g. 720 x 480) to HD quality (1920 x 1080), causing the quality to look poor.

    When viewing a video from an external device:
    When using a set-top box, recording device, or other external device that does not support HD quality, videos are displayed in SD quality. Even when the external device supports HD quality, if the device is connected to the TV by an analog method, videos will not be displayed in HD quality.
