Depending on the model of your TV, you may have several options for connecting external devices, including Audio/Video in to the TV, and Sound out from the TV.


Select the type of connection you would like more information about.

HDMI (High-Definition Multimedia Interface) is a method of transmitting sound and/or video from your Media Device(cable box, video game system, etc.) to your TV, or from your ARC (Audio Return Channel) compatible TV to your sound device.

Note: Many newer TV models support HDMI (ARC), but it best to consult your user's manual to be sure.


To connect your TV using HDMI (In):

  1. Connect an HDMI cable from the HDMI output on your media device, to the HDMI input on your TV.
  2. Make sure the both the media device and the TV are powered On.
  3. Set the Input on your TV to match the input you plugged the HDMI cable into.
  4. That's all there is to it! You're done.

To connect your TV using HDMI (ARC) (Out):

Note: Simplink will need to be enabled for ARC to function.

  1. Make sure both the sound device and the TV are powered On.
  2. Connect an HDMI cable from the HDMI (ARC) output on your TV (usually HDMI 1), to the HDMI input slot on the sound device.
  3. Locate the Sound menu on your TV (differs by model).
  4. Select Sound Out from the Sound menu.
  5. Choose Audio Out(Optical/HDMI ARC)from the list.
  6. Your sound device should automatically switch to ARC mode.
  7. If not, change the input on the sound device to match the port you plugged the optical cable in to. On LG Home Theaters, Sound Plates, and Sound Bars, use the Function button either on the unit or on the remote. For other manufacturer's devices, consult the user's manual (usually Function, Input, or Source).
  8. If you do not hear sound when a title is playing, check the volume level. The volume indicator is different depending on the device manufacturer, for LG devices ensure the volume level is above 10; for other manufacturers, consult the user's manual.

USB is a common connection type used for external hard drives/flash drives, cameras, and smart phones/tablets. Media files from these devices (videos, pictures, or music) can be played on many TVs.

Note: Some USB devices may not be compatible depending on formatting and size, check your owner's manual for specific restrictions.


To connect your TV using USB:

  1. Plug the USB cable from your USB device into the TV.
  2. Use Smart Share to access and play your media files.
  3. The Smart Share article also provides some troubleshooting steps in case things don't work properly.

Digital Optical cables deliver crystal clear sound using fiber optic technology (uses light to transmit data).

Note: Most TV models support optical output, but it is best to consult the manual to be sure.


To connect your TV using Digital Optical (Out):

  1. Connect an optical cable from the optical output on your TV, to the optical input port on your sound device.
  2. Make sure both the TV and the sound device are powered On.
  3. Change the input on the sound device to match the port you plugged the optical cable in to. On LG Home Theaters, Sound Plates, and Sound Bars, use the Function button either on the unit or on the remote. For other manufacturer's devices, consult the user's manual (usually Function, Input, or Source).

Component video cables (Red, Blue, Green, White and Red) deliver analog HD video with stereo sound from your Media Device(cable box, video game system, etc.) to your TV.

Note: The Red and White cables should be visually separated, or next to each other on one side of the cabling. These are the stereo audio cables.


To connect your TV using Component video:

  1. Connect the cables, matching the colors, from the Component video output on the media device to the Component video input on the TV.
  2. Make sure both the media device and the TV are powered On.
  3. Change the input on the TV to match the port you plugged the Component video cables into. There should be a button, either on the TV or on the remote, called Input, which will cycle between inputs (or allow you to choose a specific one).
  4. Play some form of media from your media device.
  5. If you do not hear sound when a title is playing, check the volume level. Ensure the volume level is above 10.

RCA cables (Red, White, and Yellow) deliver analog video with stereo sound from your Media Device(cable box, video game system, etc.) to your TV, or from your TV to a sound device.

Note: Most TV models do not support RCA output, but it is best to consult the manual to be sure.


To connect your TV using RCA(Composite Video) (In):
