Overview

The StarTech HDBOOST4K2 is a compact HDMI signal booster designed to extend 4K@60Hz video signals up to 45 feet (14 meters) using certified HDMI cables. This device is essential for maintaining signal integrity over longer cable runs, preventing signal degradation, and ensuring a clear, artifact-free image for high-resolution video distribution in surveillance, digital signage, or home theater applications. It supports the full 18Gbps bandwidth required for uncompressed 4K video with 4:4:4 chroma subsampling and HDCP 2.2 content protection.

Compatibility

This booster is compatible with any HDMI source device and display that supports 4K@60Hz resolution, 18Gbps bandwidth, HDCP 2.2, and 4:4:4 chroma subsampling. It functions as a plug-and-play device, requiring no software installation. For optimal performance, use certified HDMI cables rated for 18Gbps bandwidth on both the input and output connections.
