HDMI 2.1 Cable StarTech 3m — 48Gbps, 8K60 / 4K120, HDR10+, eARC, HDMI Type A Male–Male

Certified StarTech HDMI 2.1 Cable, 3 m length, provides up to 48 Gbps bandwidth to support resolutions up to 8K at 60 Hz and 4K at 120 Hz. The cable features HDMI Type A male-to-male connectors with gold-plated contacts, a durable die-cast aluminium connector sub-structure, and a flexible TPE jacket in black/grey. It supports HDR10+ and Dolby Vision for improved contrast and color, eARC/ARC for enhanced audio return with multi-channel uncompressed audio formats, and HDCP 2.3 content protection. This HDMI 2.1 certified cable is backward compatible with earlier HDMI specifications and is suitable for TVs, monitors, gaming consoles and AV receivers.

Advantages

The cable’s Ultra High Speed HDMI 2.1 certification ensures verified support for high bandwidth features up to 48 Gbps and reduces the risk of compatibility issues with 8K/4K sources and displays. Corrosion-resistant gold-plated connectors and a die-cast aluminium sub-structure improve signal integrity and durability, while braided shielding and aluminium-mylar foil reduce electromagnetic interference. A flexible, halogen-free TPE jacket combined with reinforced strain relief increases longevity and ease of installation in home theater and professional AV setups.

How to use

Connect one HDMI Type A male end to the HDMI output of your source device (for example a gaming console, Blu-ray player or PC graphics card) and the other HDMI Type A male end to the HDMI input on your display or AV receiver. Ensure both devices are powered off when connecting to avoid hot-plug issues, then power on the devices and select the appropriate HDMI input on your display or receiver. For full 8K/4K120 functionality, confirm that both source and display support HDMI 2.1 features and enable required settings such as HDR, variable refresh rate (if available), and eARC in device menus.

Usage recommendations

For optimal performance, use this certified Ultra High Speed HDMI 2.1 cable for direct HDMI connections up to 3 m without additional adapters. Avoid tight bends and kinks in the cable, maintain gentle strain relief at connector ends, and keep the cable away from strong sources of electromagnetic interference. Verify device settings and cable seating if you experience reduced resolution or audio issues.
