• Position the transmitter near the HDMI source and the receiver near the display, ensuring the IR emitters/receivers are placed for optimal line-of-sight control.
• Connect any included power adapters if your installation requires external power at the transmitter or receiver ends.
• Power on the source and display, then configure the display to the correct input and verify the HDBaseT link indicators (if present) show a healthy connection.

Frequently asked questions

Q: What resolutions does the Gefen 4K Ultra HD HDBaseT Extender support?

A: It supports up to 4K Ultra HD (3840 x 2160) at 60 Hz with 4:2:0 chroma subsampling. For standard HD content, the extender delivers reliable performance up to 1080p across the maximum distance supported by HDBaseT.

Q: How far can I run the HDMI signal with this extender?

A: At 1080p, you can extend up to 230 feet (70 meters). When transmitting 4K content, the maximum distance is approximately 130 feet (40 meters). Distances beyond these specifications may require amplified or different installation configurations.

Q: Is there IR control both ways?

A: Yes. The GTB-UHD-HBTL model provides 2-way infrared (IR) control, enabling you to use a remote from either end of the setup for convenient operation without repositioning equipment.

Q: What cabling do I need?

A: A single CAT-5e or better Ethernet cable is used to carry the HDBaseT signal between transmitter and receiver. Higher-grade cables (CAT-6 or CAT-6a) can provide additional interference resistance and headroom for longer runs, especially in challenging environments.

Q: Do I need to separately power the extender?

A: Depending on your installation and PoH (Power over HDBaseT) support, you may power the transmitter and receiver with their respective external power adapters if PoH is not available or enabled in your setup. Always refer to the included accessory guide to determine the correct power configuration for your installation.

Q: Can this extender be used in multi-room or commercial environments?

A: Absolutely. The GTB-UHD-HBTL is designed for multi-room and professional installations, including home theaters, classrooms, corporate conference rooms, and digital signage. Its HDBaseT approach reduces cable sprawl while delivering high-quality video and audio with reliable control capabilities.

Q: Are there any special setup considerations for 4K content?

A: When delivering 4K at 60 Hz, ensure your source, sender, and display all support matching 4K specifications, and use a high-quality CAT cable designed for high-bandwidth transmission. Keep runs within the specified distances and minimize electrical interference sources to maintain consistent color and brightness.

Q: Is the GTB-UHD-HBTL compatible with other HDBaseT devices?

A: Yes. HDBaseT devices are designed to be interoperable where compatibility is within the HDBaseT standard. For best performance, follow Gefen’s recommended pairing and cabling guidelines and ensure firmware on devices is up to date.
