Gefen ToolBox 4x4 Matrix for HDMI 4K x 2K

The black Gefen ToolBox 4x4 Matrix for HDMI 4K x 2K is a compact and lightweight, surface-mountable HDMI matrix that lets you route up to four Ultra HD or 1080p sources to up to four Ultra HD displays. It supports resolutions up to 3840 x 2160 at 30p, making it a practical choice for distributing HDCP-compliant 4K content across multiple screens in a single room or across zones.

Designed for Multi-Display 4K Distribution

Built for reliable signal routing in real-world installs, this 4x4 matrix is well suited for home theater systems, multi-room installations, retail environments, sports bars, schools, hospitals, and lobbies. It supports 12-bit Deep Color, 3DTV pass-through, and Lip Sync pass-through to help preserve picture fidelity and maintain proper audio-to-video timing.

Audio Format Support for Home Theater and Pro AV

For systems where audio matters as much as video, the matrix supports lossless and multichannel formats including LPCM 7.1, Dolby TrueHD, Dolby Digital Plus, and DTS-HD Master Audio. This makes it a strong fit for AV receivers, soundbars, and integrated speaker systems that need full-format pass-through.

Fast Switching and EDID Control for Smoother Integration

Gefen FST (Fast Switching Technology) is designed to speed up the HDCP authentication process when changing routes, helping reduce delays during switching. Advanced EDID Management helps streamline setup with mixed sources and displays, which can be especially helpful when integrating 4K and 1080p devices on the same system.

Multiple Control Options for Installations

Use the front-panel push buttons for routing, FST modes, audio, and EDID management, or integrate the matrix into a control system using the RS-232 port. For networked environments, it also supports IP control via Telnet, UDP, and a built-in web server interface. Firmware is field-upgradeable via Mini-USB and IP ports to support ongoing maintenance.
