4K 2x2 Video Wall Controller

Discover the Power of a True 4K 2x2 Video Wall Controller 

The 4K 2x2 Video Wall Controller is a dedicated 1-in-4-out HDMI/DVI video wall processor. It supports one HDMI or DVI input signal and distributes it across four HDMI outputs to create a stunning 2x2 large-screen display. A built-in 3.5mm audio output extracts the original audio for external speakers or sound systems. Powered by a stable DC12V/2A adapter, the unit is compact, energy-efficient, and ready for 24/7 commercial operation. It fully supports HDCP 4K@30Hz, ensuring protected content plays smoothly without black screens or compatibility issues.

What makes this controller stand out in real-world installations?
• True 4K Input Capability - Accepts up to 3840×2160@30Hz sources (Blu-ray, media players, computers, or cameras) while outputting stable 1080p to each screen.

• Perfect Image Division - Splits one complete high-definition signal into four synchronized blocks for a seamless 2x2 video wall - no tearing, no lag.

• Flexible Audio Extraction - Dedicated 3.5mm output lets you route sound to external amplifiers or speakers independently.

• Professional RS232 Control - Integrate with third-party control systems (Crestron, AMX, or simple serial commands) for automated operation via the RJ45 port.

• Plug-and-Play Simplicity - No drivers, no apps, no complicated setup. Just connect cables and power on - the wall is ready in minutes.

• Reliable 24/7 Operation - Industrial-grade components and stable power design ensure it runs continuously in commercial environments.
