2x1 4K30 HDMI/USB-C US Wall-Plate Switcher 40m-HDBT Tx

The Kramer WP-20CT/US-D(W/B) is a 2×1 automatic wall-plate switcher and HDBaseT transmitter designed to place HDMI and USB-C source connections at the point of use. It detects active video signals and can switch according to either source priority or the last-connected source. Built-in Maestro room control adds an intelligent control layer within the compact US-D wall-plate format.

Ideal Use Cases

This model fits installed AV spaces where users need a direct choice between a conventional HDMI source and a USB-C video device. Placing both interfaces at the wall gives the user a defined connection point while the selected signal travels over long-reach HDBaseT. The listed 40m transmission capability supports layouts in which the source position and receiving equipment are separated. Automatic switching also reduces the need to operate a separate source selector.

Why Choose This Model

WP-20CT combines two source interfaces in one US-D-size device: HDMI for compatible AV sources and USB-C for compatible USB-C video sources. Active-video detection drives its automatic behavior, and the available switching functions include standard priority and last-connected operation. A priority-based workflow can preserve the preferred input order, while last-connected switching can respond when another active source is attached. White and black Decora design frame sets provide two supplied finish choices for the wall plate.

Installation and Integration

The US unit measures 6.98cm wide by 3.10cm deep by 11.43cm high, equivalent to 2.75 x 1.22 x 4.50 inches. It uses the US-D wall-plate format and is supplied in the WP-20CT/US-D(W/B) configuration with white and black Decora design frame sets. Its long-reach HDBaseT transmitter architecture carries the selected signal toward a compatible receiving endpoint. The source data also lists CAT6A U/FTP video and LAN cable assemblies and bulk cabling among related cable options. The transmission distance identified for this product listing is 40m.

Performance Highlights

The product listing identifies 4K30 operation, while the supplied technical data also identifies 4K60 at 4:2:0, a 60Hz refresh rate, and 10.2Gbps bandwidth. These entries should be considered when matching the wall-plate transmitter to the required system format. The product handles 4K HDMI and USB-C video signals, selects between its two source paths, and sends the chosen signal through one long-reach HDBaseT transmission path. Active signal detection supplies the information required for its automatic switching behavior.

What Makes It Different

Unlike a passive connection plate, WP-20CT evaluates whether an active video signal is present and uses that information to manage source selection. Its combination of automatic switching, priority or last-connected logic, and built-in Maestro room control defines its role in an installed AV system. HDMI and USB-C are managed within the same 2×1 front end, while HDBaseT moves the chosen signal beyond the wall plate. This creates one installed connection point that handles both source access and signal transmission.

Final Assessment

For an installation that specifically calls for a US-D Decora wall plate, two source types, and a single HDBaseT feed, WP-20CT/US-D(W/B) combines the required functions in one compact unit. Its strongest fit is a system that benefits from automatic active-signal detection and a choice between priority-based and last-connected switching. The supplied listing title states 4K30, while the extracted technical data states 4K60 4:2:0 at 60Hz, so the desired timing should be confirmed against the complete signal chain. White and black frame sets support either supplied finish at installation.
