Use a cable shorter than 10 feet (3 m) to get the best UHD contents viewing quality.
Many computer graphics adaptors do not have HDMI ports, but have DVI ports instead. If your PC does not
support HDMI video out, connect your PC with an HDMI-DVI cable.
For One Connect supported models, when the TV is connected to an external device such as a DVD/BD player
or a set-top box via HDMI, power sync mode will be automatically activated. In this power sync mode, the
TV continues to detect and connect external devices via HDMI cable. This function can be deactivated by
removing HDMI cable of connected device.
Connection notes for audio devices
For better audio quality, it is a good idea to use an AV receiver.
If you connect an external audio device using an optical cable, the Sound Output setting is automatically
changed to the connected device. However, to make this happen, you must turn on the external audio device
before connecting the optical cable. To manually change the Sound Output setting, do one of the following:
Use the Quick Settings screen to change to the connected device:
Use the Select button to select Audio Out/Optical on the Sound Output menu. ( Settings up
directional button Sound Output).
Use the Settings screen to change to the connected device:
Select Audio Out/Optical on the Sound Output menu. ( Settings Sound Sound Output).
An unusual noise coming from a connected audio device while you are using it may indicate a problem with
the audio device itself. If this occurs, ask for assistance from the audio device's manufacturer.
Digital audio is only available with 5.1 channel broadcasts.
