Enhanced capabilities provided by eARC

Compared to the ARC standard, eARC provides a better sound experience. In addition, the upgrade gives you additional features and benefits that can improve the audio streaming process. These include:

  • An uncompressed data transfer of audio formats
  • Three-dimensional surround sound
  • Reduced latency compared to standard ARC
  • Automatic configuration functionality for selected devices
  • Backward compatibility to the older ARC standard
  • Informations sent by the AV receiver to the TV about the supported sound formats
  • Automatic output of the best possible sound signal

Note: In order to use this standard, all connected devices must be eARC-capable. If this is not the case, the bandwidth advantage is lost and with it possibly also the option to transmit full 3D sound like Dolby Atmos or DTS:X. Basically, the integration is also possible from HDMI 2.0 and can be activated later via software update.
