eARC is an advanced version of the Audio Return Channel (ARC) audio link found in HDMI connections. It enables transmission of high-bitrate audio formats such as Dolby TrueHD and DTS-HD Master Audio, allowing uncompressed full-resolution audio signals to pass through the monitor and be sent directly to external audio devices such as a soundbar via HDMI, simplifying setup and delivering richer, more detailed soundscapes for deeper immersion in AAA titles.
The benefits of eARC in gaming are manifold. It supports uncompressed audio to prevent the degradation of sound quality transmission, which is particularly important for AAA games that rely heavily on atmospheric sound effects and intricate audio details to create compelling experiences. eARC also reduces audio latency, which is equally important as video response time and crucial in games where timing is everything. Reduced latency means that the sound you hear is more closely synchronized with the action on the screen, giving you a competitive edge in fast-paced games.
eARC simplifies setup by reducing the number of required cables. Unlike traditional setups that require multiple cables to connect the monitor and sound system, eARC can transmit audio directly from the monitor to the sound system through a single 「Ultra High Speed」 HDMI cable, decluttering the gaming space and streamlining the setup process.
In terms of audio quality, eARC is a game-changer, supporting higher bandwidth and the latest high-bitrate audio formats up to 192kHz, 24-bit, and uncompressed 5.1 and 7.1, as well as 32-channel lossless audio formats. eARC is also compatible with advanced audio standards such as DTS-HD Master Audio, Dolby TrueHD, DTS: X and Dolby Atmos, providing high-fidelity sound that matches the stunning visuals of immersive AAA gameplay and enhancing overall gaming experiences.
Futureproofing is another critical advantage of eARC. As audio and video technologies continue to evolve, eARC ensures that your setup remains compatible with the latest formats and standards, minimizing the need to upgrade cables or connections, providing long-term value, and keeping your gaming rig ahead of the curve.
