Sky HD is a high-definition satellite service, and its users get a Sky HD converter box. Sky satellite dishes must be installed by an authorised technician. According to the Sky HD manual, the settings for Sky HD refer to the picture and sound settings, which can be controlled from the Sky HD remote.
To access the settings press the "Services" button. Scroll to the right using the arrow keys on the remote and select "Settings;" it is highlighted by a wrench icon. Use the arrow keys to select "Picture" or "Audio" settings.
Sky HD has four picture settings; "Automatic," "576," "720p" and "1080i." 576 is for non-HD programs, while 720p and 1080i are for HD programs. 1080i is the highest resolution setting. However, not all programs are in HD. The best picture setting is automatic. The automatic setting will determine the highest quality picture setting available for that program/channel and select it. This way the user does not need to constantly adjust picture settings.
The best sound settings are determined by the receiver and/or TV's configuration. Older receivers may not support Dolby Surround Sound. Under sound settings, select either "Digital Audio Output - Optical," or "Digital Audio Output - HDMI;" select the one current configured; most users will have HDMI as the current configuration. Move the arrow to the right and select "Dolby D." This is the best audio setting for Sky HD.
HDMI vs. Optical
The Sky HD converter offers users two choices for output; HDMI or Optical. HDMI is the higher quality output method and is recommended to keep the best settings. Optical is for older model support devices and of lower quality. If possible, use HDMI
