Overview

The Monoprice 143221 8K Ultra High Speed HDMI Cable is built to handle the demanding bandwidth requirements of modern home entertainment and gaming systems. With 48Gbps of throughput, it supports uncompressed 8K video at 60Hz and 4K at 120Hz, and can push resolutions up to 10K@120Hz when using VESA Display Stream Compression 1.2a. Dynamic HDR support ensures that brightness, contrast, and color depth are optimized on a scene-by-scene or frame-by-frame basis for the most lifelike picture quality available.

At 15 feet, this cable provides generous length for routing between components in a media room, home theater, or gaming setup without requiring extenders or repeaters. The eARC feature delivers lossless, object-based audio formats like Dolby Atmos and DTS:X from your TV back to a soundbar or AV receiver over a single cable. Gaming-specific features include Variable Refresh Rate support and AMD FreeSync compatibility with PlayStation and Xbox consoles. The unbranded, no-logo connector design makes it a clean choice for custom installations where visible branding is unwanted.
