4K HDR HDMI Wall-Plate

Ideal Use Cases

The Kramer WP-871XR/US(W/B) is designed for installations that need to place an HDMI connection in a US D-size, 1-gang wall location while transmitting the signal to a compatible receiver over twisted pair. It is particularly suited to systems requiring full 4K@60Hz video with 4:4:4 color sampling, HDR support, HDCP 2.2 compatibility, and transmission distances beyond those of a conventional HDMI cable. The wall-plate format also provides a practical connection point wherever the HDMI source and receiving equipment must be installed in separate locations.

Why Choose This Model

This transmitter combines HDMI signal conversion, long-reach DGKat 2.0 transmission, and Power over Copper in one wall-mounted device. It accepts an HDMI input, converts that signal to DGKat 2.0, and sends it across twisted-pair cable to a compatible receiver. Its 18Gbps bandwidth supports demanding 4K signals, including 4K@60Hz with 4:4:4 color sampling. HDR10 support preserves compatibility with high-dynamic-range content, while HDCP 2.2 support accommodates protected HDMI sources and displays.

The US version includes both white and black Decora design frame sets, allowing the visible finish to be selected for the installation. Its compact 1-gang format measures 6.98cm wide by 3.10cm deep by 11.43cm high, or 2.75 by 1.22 by 4.50 inches.

Installation and Integration

The WP-871XR/US(W/B) installs as a US D-size wall-plate transmitter. Connect the HDMI source to the wall plate, connect the DGKat 2.0 twisted-pair link to a compatible receiver, and use the receiver to deliver the recovered signal at the destination. The transmitter is powered through PoC, or Power over Copper, carried over the twisted-pair cable. This eliminates the need for a separate local power connection at the wall plate when it is used within a compatible PoC system.

Specified extension distances are based on Kramer shielded cables. The transmitter reaches up to 60m, or 200ft, for 4K@60Hz signals with 4:4:4 color sampling. For 4K@30Hz at 4:4:4 and 24bpp, the maximum stated reach increases to 70m, or 230ft. Cable selection, signal format, and receiver compatibility should therefore be considered together when planning the link.

Performance Highlights

• Transmits 4K@60Hz video with 4:4:4 color sampling up to 60m or 200ft.
• Extends 4K@30Hz, 4:4:4, 24bpp video up to 70m or 230ft.
• Provides 18Gbps signal bandwidth and a maximum listed refresh rate of 60Hz.
• Supports HDR10 for compatible high-dynamic-range sources and displays.
• Supports HDCP 2.2 protected HDMI signals.
• Converts an HDMI input into a long-reach DGKat 2.0 signal.
• Receives operating power through PoC over the twisted-pair connection.

These capabilities make the transmitter suitable for signal paths where resolution, color detail, HDR compatibility, and extension distance must be maintained together. The stated 4K@60Hz capability retains full 4:4:4 sampling rather than requiring a reduced chroma format.

What Makes It Different

The defining feature of the WP-871XR is its combination of full-bandwidth 4K HDR transmission and a compact wall-plate form. Rather than functioning as a simple HDMI pass-through, it converts HDMI to Kramer DGKat 2.0 for long-distance transport over twisted pair. PoC further consolidates the installation by powering the wall plate through that link. The included white and black Decora frame sets distinguish this US configuration and provide two supplied finish options without changing the transmitter itself.

Final Assessment

The Kramer WP-871XR/US(W/B) is a focused solution for extending an HDMI source from a US 1-gang wall plate to a compatible DGKat 2.0 receiver. Its core strengths are clearly defined: 18Gbps bandwidth, 4K@60Hz 4:4:4 transmission up to 60m, 4K@30Hz 4:4:4 24bpp transmission up to 70m, HDR10, HDCP 2.2, and PoC operation. For installations built around compatible receivers and Kramer shielded cabling, it provides a compact long-reach HDMI input point with both white and black frame sets included.
