Frequently Asked Questions

• What is the Gefen 1x4 DVI Distribution Amplifier used for? It is designed to distribute a single DVI source to four displays, ensuring consistent image quality and synchronized playback across multiple screens.
• Can I use this device with HDMI displays? It is a DVI-D distribution device. For HDMI displays, you can use DVI-to-DVI connections where appropriate, but audio signals will not be carried by DVI and you may need separate audio solutions.
• Will all four displays show the same image? Yes. This is a 1x4 distribution amplifier intended to mirror the same source to all connected outputs.
• Does it support HDCP-protected content? Yes, the unit is HDCP compliant on DVI connections, enabling protected material playback when allowed by the source and display.
• What about the wiring length? The built-in signal amplification helps maintain quality over longer runs, but optimal performance is achieved with reasonably short, high-quality DVI cables and proper cable management.
