HDMI 2.1 cable StarTech 1 m — Ultra High Speed 48 Gbps, 8K@60Hz / 4K@120Hz, HDR10+, eARC, HDMI Type A male–male, black

Certified Ultra High Speed HDMI 2.1 cable designed for reliable 8K connections in enterprise, AV and IT environments. The HDMI 2.1 specification is permanently etched on each connector to confirm compatibility and support for high-bandwidth features. The cable supports 8K@60Hz, 5K@60Hz, 4K@120Hz and up to 48 Gbit/s bandwidth, HDR10+ and Dolby Vision, eARC and multi-channel immersive audio, as well as HDCP 2.3 for secure content delivery. The halogen-free TPE jacket and robust strain reliefs provide flexibility for routing, while aluminum‑Mylar foil with a braided shield reduces EMI; gold-plated connectors resist corrosion and are rated for 10,000+ insertions.

Advantages

This HDMI 2.1 cable is certified by an HDMI Authorized Test Center to ensure support for high-bandwidth HDMI 2.1 features and backward compatibility with earlier HDMI versions. Permanent etching on each connector provides immediate identification of HDMI 2.1 capability. The construction combines a flexible, RoHS‑compliant halogen-free TPE jacket with layered shielding to minimize interference and gold-plated contacts for durability and long-term signal integrity. The cable is EMI-tested for use in dense or shared environments and is suitable for professional AV installations, workstations, video walls and enterprise deployments.

How to use

Connect one end of the HDMI Type A plug to the HDMI output of your source device and the other end to the HDMI input of the display, AV receiver or video wall. The permanently etched HDMI 2.1 marking on each connector confirms the cable supports Ultra High Speed features. For systems using USB‑C (DP Alt Mode), use a compatible USB‑C to HDMI adapter to connect DP Alt Mode devices and Apple M‑series MacBooks. Route the cable using gentle bends to avoid sharp kinks; the flexible TPE jacket allows installation behind displays, around corners and between equipment.

Recommendations

Use this certified Ultra High Speed HDMI 2.1 cable for high-resolution workflows and AV installations that require 8K, high refresh rates, HDR and immersive audio. Verify device HDMI 2.1 compatibility and, when integrating with USB‑C sources, choose a DP Alt Mode–capable adapter. Avoid excessive bending near the connectors and keep the cable clear of strong EMI sources where possible.
