In this comprehensive guide, we’ll delve into the world of HDMI pass-through, exploring its benefits, limitations, and scenarios where it’s essential.
What is HDMI Pass-Through?
HDMI pass-through, also known as HDMI passthrough or HDMI bypass, is a feature that allows an audio-video receiver (AVR) or soundbar to pass through the video signal from a source device, such as a 4K Blu-ray player or gaming console, to a TV without affecting the video quality. This means that the AVR or soundbar only processes the audio signal, leaving the video signal untouched.
In traditional setups, the AVR or soundbar would need to convert the video signal, which could lead to degradation or loss of quality. With HDMI pass-through, the video signal remains in its original format, ensuring that you get the best possible picture quality.
How Does HDMI Pass-Through Work?
HDMI pass-through relies on the HDMI 2.1 standard, which introduced several new features, including eARC (enhanced Audio Return Channel) and ALLM (Auto Low Latency Mode). These features enable the seamless passthrough of video signals while allowing the AVR or soundbar to process the audio signal.
When a device is connected to an AVR or soundbar with HDMI pass-through, the device sends both video and audio signals through the HDMI connection. The AVR or soundbar then extracts the audio signal and processes it, while forwarding the video signal to the TV without any alteration. This allows you to enjoy the best possible audio quality while maintaining the original video quality.
