Kit contents and purpose

The Monoprice 121608 Blackbird 4K Pro HDBaseT Extender Kit includes a transmitter and receivers for distributing HDMI signals over a single Cat6 cable. It is designed for installers and integrators who need to route 4K video to distant displays without running long HDMI leads. The kit supports HDCP 2.2 for protected content playback. Bidirectional Power over HDBaseT removes the requirement for a separate power supply at the receiver location.

Build integration and cabling

A single Cat6 cable carries video, control and power between the transmitter and each receiver up to the rated distances. The receiver draws its operating power through the same cable, freeing the display side from mains outlets and extra adapters. An RS232 pass-through channel is provided for third-party control systems. IR accessories are not included, so infrared remote extension must be sourced separately if required.

Suitable scenarios and limits

This kit suits AV projects that need 4K at 60 Hz 4:2:0 up to 70 metres or 1080p up to 100 metres over structured cabling. It is not for installations that require 4K 4:4:4 chroma sampling or HDR metadata transport beyond the stated HDCP 2.2 baseline. Buyers who need integrated IR emitters or longer 4K reach should look at alternative extender platforms.

Questions about this item

How far can the kit reliably carry a 4K 60 Hz 4:2:0 signal before the image drops out?

The extender reaches 70 metres at 4K 60 Hz 4:2:0 and 100 metres at 1080p over a single Cat6 cable.

Does the receiver need its own power supply or does the transmitter feed it, and how much heat should I expect?

Power over HDBaseT supplies the receiver from the transmitter, so no local adapter is required and heat stays low.

Which control interfaces are built in so I can integrate the kit with my existing automation system?

The unit provides bidirectional RS-232 and IR pass-through, letting you route serial commands and remote signals over the same link.
