HDMI 2.1 AVR: The Ultimate Guide (2023)

HDMI 2.1: The Next-Gen Standard for AVRs

HDMI 2.1 is the latest version of the HDMI specification, and it brings a host of new features and improvements that make it the ideal choice for connecting your AV receiver (AVR) to your TV, gaming console, and other devices.

Key Features of HDMI 2.1

• 8K Resolution: HDMI 2.1 supports resolutions up to 8K (7680x4320 pixels), which is four times the resolution of 4K. This makes it ideal for connecting your AVR to an 8K TV or projector.
• 48Gbps Bandwidth: HDMI 2.1 has a bandwidth of 48Gbps, which is double the bandwidth of HDMI 2.0. This increased bandwidth allows for the transmission of uncompressed 8K video at 60Hz, as well as other bandwidth-intensive content.
• Dynamic HDR: HDMI 2.1 supports dynamic HDR, which allows for the display of HDR content with a wider range of colors and contrasts. This results in a more realistic and immersive viewing experience.
• eARC: HDMI 2.1 includes support for eARC (Enhanced Audio Return Channel), which allows for the transmission of uncompressed audio formats, such as Dolby Atmos and DTS:X, from your TV to your AVR. This eliminates the need for a separate audio cable.
• ALLM: HDMI 2.1 includes support for ALLM (Auto Low Latency Mode), which automatically reduces latency for gaming. This results in a more responsive and immersive gaming experience.
• VRR: HDMI 2.1 includes support for VRR (Variable Refresh Rate), which allows your TV or monitor to match the refresh rate of your gaming console. This eliminates screen tearing and stuttering, resulting in a smoother and more enjoyable gaming experience.

Benefits of HDMI 2.1 AVR

There are many benefits to using an HDMI 2.1 AVR, including:

• Improved video quality: HDMI 2.1 supports 8K resolution and dynamic HDR, which results in a more realistic and immersive viewing experience.
• Enhanced audio quality: HDMI 2.1 includes support for eARC, which allows for the transmission of uncompressed audio formats, such as Dolby Atmos and DTS:X. This results in a more immersive and realistic audio experience.
