What is the difference between HDMI 1.4, 2.0, and 2.1?
The main difference between HDMI 1.4, 2.0, and 2.1 lies in the bandwidth and features they support. HDMI 1.4, the oldest of the three, has a bandwidth of 10.2 Gbps and supports resolutions up to 4K at 30Hz. HDMI 2.0, on the other hand, has a bandwidth of 18 Gbps and supports resolutions up to 4K at 60Hz. HDMI 2.1, the latest version, has a bandwidth of 48 Gbps and supports resolutions up to 8K at 60Hz, as well as other advanced features like variable refresh rate and auto low latency mode.
In the context of a soundbar, the choice of HDMI version depends on the capabilities of your TV and other devices connected to the soundbar. If your TV only supports 4K at 30Hz, an HDMI 1.4 cable might be sufficient. However, if you have a 4K TV that supports higher refresh rates or an 8K TV, you’ll need an HDMI 2.0 or 2.1 cable, respectively, to take full advantage of its capabilities.
What is ARC, eARC, and what’s the difference?
ARC, or Audio Return Channel, is a feature that allows a TV to send audio signals back to a soundbar or receiver over an HDMI connection. This eliminates the need for a separate audio cable, making it a convenient feature for homeowners with limited cable space. eARC, or enhanced Audio Return Channel, is an improved version of ARC that supports higher-quality audio formats like Dolby Atmos and DTS:X.
The main difference between ARC and eARC is the level of audio quality they support. ARC is limited to transmitting audio signals up to 5.1 channels, while eARC can transmit up to 7.1 channels, as well as object-based audio formats like Dolby Atmos and DTS:X. If your soundbar supports eARC, it’s recommended to use an eARC-compatible HDMI cable to take full advantage of its audio capabilities.
