Troxell SKU



Simultaneously displays up to four 4K sources on a single display. Automatically reconfigures as sources are connected and disconnected. Works standalone or integrated with a control system. Works with Crestron Connect It™ cable caddies for huddle room applications.



The HD-WP-4K-401-C enables the display of up to four video sources simultaneously on a single HD, Ultra HD, or 4K display. Parallel HDMI® and HDBaseT® outputs provide flexible connectivity for the display device and other equipment. Input sources up to 4K are supported via four HDMI inputs. Fully automatic operation enables use without a control system, while enhanced operation and custom functionality can be attained through integration with a control system.

Video windowing enhances the presentation and collaboration capabilities of any meeting space, allowing multiple presentation sources to be connected and displayed together on screen. The ability to connect up to four Crestron Connect It™ cable caddies directly to the HD-WP-4K-401-C affords a perfect multi-window collaboration solution for huddle rooms and classrooms. Any meeting room, classroom, training lab, auditorium, lecture hall, house of worship, or command center can benefit from the use of video windowing, expanding the facility's display capabilities while saving cost by allowing more video sources to be viewed on fewer display devices.

Note: Interlaced video signals are not supported. A Crestron HD-SCALER-HD-E video scaler may be added to any HDMI input to enable support for interlaced video sources on that input. Refer to the specifications for complete input and output capabilities.

Note: Full screen 4K display is supported by Inputs 1 and 2 only. 4K sources connected to Inputs 3 and 4 are automatically downscaled to 1080p.[1]

High-Performance Video Windowing
The HD-WP-4K-401-C is engineered to deliver a professional onscreen experience with crystal clear 4K video quality and smooth transitions. Using Automatic mode, the screen fluidly configures itself based on the number of connected sources. With four sources connected, all four images appear in four equal sized windows that combine to fill the screen. Disconnect or disable one source and the screen reconfigures to display only three windows (two top, one bottom). Connect or select only two sources and they display side by side, while a single source displays full screen.

PIP (Picture-In-Picture) windowing is also supported, allowing one source to be displayed full screen with a second source displayed in an inset PIP window. The size and location of the PIP window can be defined at setup. All windowing modes and input assignments can be managed at setup or while in operation using the front panel controls, a web browser, or a control system.

Text & Image Overlay
Each video window can be designated with a custom text label. An additional text field can be positioned at any location on screen to display a static label or a dynamic pop-up message sent from the control system. A custom photo or logo image can also be uploaded to appear at any location on the screen.

Crestron Connect It™
Crestron Connect It is a cost-effective, simple-to-use presentation solution that works seamlessly with the HD-WP-4K-401-C. Simply add up to four Crestron Connect It Cable Caddies (TT-100 series) to provide BYOD connectivity and one-touch control for multiple participants around a conference table. Four USB ports on the HD-WP-4K-401-C provide power and communications for each cable caddy.

Note: The HD-WP-4K-401-C does not support VGA or analog audio inputs.

HDBaseT® Output
Its HDBaseT output allows the HD-WP-4K-401-C to connect directly to any display device equipped with an HDBaseT input. The HDBaseT connection requires just one CAT type cable and supports wiring distances up to 300 feet (100 meters), easily accommodating all types of room configurations. The HDBaseT and HDMI outputs may be used simultaneously, providing identical signals at each output with the added benefits of longer cable length and the ability to power an HDBaseT PoE+ powered device over the HDBaseT connection.

The HDBaseT output is also compatible with Crestron DigitalMedia™ (DM®), allowing for connection to a DM 8G+® receiver, DM switcher, Crestron RL® 2 Group Collaboration System, or DM-DGE-200-C Digital Graphics Engine. Please note that the HD-WP-4K-401-C does not provide control of the DM device or any equipment connected to that DM device.

Audio Pass-Through & De-Embedding
When displaying a full screen image of any single input source, that source's audio signal is routed to the HDMI and HDBaseT outputs. A balanced analog audio output is also included to allow stereo audio signals to be extracted from the digital output and fed to a separate audio switcher, processor, or amplifier.

Display Control & System Integration
When used without a control system, the HD-WP-4K-401-C provides essential on/off power control of the display device, via RS-232 using the onboard COM port, or via CEC through the HDMI or HDBaseT output. The display device can be configured to turn on automatically when an input source is connected, and then turn off following an adjustable time period after all sources are disconnected.

Adding a control system enables fully customizable control of the display and other devices connected to the HD-WP-4K-401-C via RS-232, IR, and CEC. CEC is supported through each of the onboard HDMI and HDBaseT ports. Integration with a control system also enables integration with Crestron Fusion® Cloud to support centralized control, monitoring, and room scheduling as part of a complete managed enterprise.

Simplified Setup
Easy setup and configuration of the HD-WP-4K-401-C is enabled using the front panel controls or a web browser. Standalone operation is supported for set-and-forget video windowing applications, and for small AV presentation applications with or without the optional Crestron Connect It Cable Caddies.
