Overview

The Monoprice 142684 8K Certified Braided Ultra High Speed HDMI Cable is built to handle the most demanding video and audio signals available today. With full HDMI 2.1 support and 48Gbps of bandwidth, it can carry 8K video at 60Hz or 4K at 120Hz — making it ready for the latest gaming consoles, high-end graphics cards, and next-generation 8K displays. It also supports Dynamic HDR, Enhanced Audio Return Channel (eARC), Variable Refresh Rate (VRR), and Auto Low Latency Mode (ALLM), covering the full feature set that modern home theater and gaming setups demand.

At 15 feet, this cable provides enough reach for wall-mounted TVs, projector setups, and larger entertainment centers without requiring signal boosters or active cable technology. The high-strength braided exterior is designed to withstand repeated flexing, resist tangling, and hold up to the wear of being routed behind furniture or through conduit. Each cable has been tested and certified by an HDMI authorized testing center, giving buyers confidence that it will deliver its rated performance consistently. Full backward compatibility with earlier HDMI versions means it will also work seamlessly with older devices at their supported resolutions and refresh rates.
