CLUB3D Ultra High Speed HDMI Extension Cable 4K120Hz 8K60Hz 48Gbps M/F 1 m / 3.28 ft 30AWG

The Club 3D CAC-1322 Ultra High Speed HDMI™2.1 Extension Cable supports the full HDMI 2.1 specification, providing increased bandwidth up to 48 Gbps and enabling high-resolution video and audio transmission. By doubling the bitrate per data channel and expanding the number of channels, the cable allows for resolutions such as 4K at 120 Hz and 8K at 60 Hz, and includes support for Display Stream Compression (DSC) 1.2 for formats beyond 8K with 4:2:0 chroma subsampling.

Advantages

This extension cable fully implements HDMI 2.1 features, offering improved video quality and reduced latency for compatible devices. It supports Variable Refresh Rate (VRR) to reduce lag and tearing, Quick Media Switching (QMS) to remove blank-screen delays when switching video content, Quick Frame Transport (QFT) to lower latency, and both static and dynamic HDR metadata for enhanced contrast and color fidelity. The CAC-1322 is suitable for gaming, high-frame-rate video, and future-proof HDMI connections.

Key specifications

• Standard: HDMI™ 2.1
• Maximum bandwidth: 48 Gbps
• Supported resolutions: up to 4K@120 Hz and 8K@60 Hz
• Data channels: 4 channels, 12 Gbps per channel
• Display Stream Compression: DSC 1.2 support
• Refresh features: VRR, QMS, QFT
• HDR support: Static and Dynamic HDR metadata

How to use

Connect the CAC-1322 extension cable between an HDMI 2.1 source device (such as a compatible graphics card, console or AV receiver) and an HDMI 2.1 display or capture device. Ensure both connected devices support HDMI 2.1 features to benefit from higher resolutions, increased refresh rates and reduced latency. Use appropriate device settings (resolution, refresh rate, HDR and VRR options) to enable desired output. For best results, keep cable runs within recommended lengths for passive HDMI 2.1 cables and avoid sharp bends.

Recommendations

Verify that both source and display support HDMI 2.1 to utilize full 48 Gbps bandwidth and advanced features like VRR, QMS, QFT and DSC 1.2. For optimal performance with high resolutions and frame rates, use compatible hardware and configure display settings accordingly.
