Lightware UCX-4x3-HCM40 – USB-C Dual Screen HDMI Matrix Switcher

Product Overview

The Lightware UCX-4x3-HCM40 is a USB Type-C dual screen extended desktop and HDMI 2.0 matrix switcher designed for BYOD and BYOM meeting room deployments. It delivers two independent 4K displays through a single USB-C cable, eliminating the need for multiple cables at the table. The device supports 4 inputs (2x HDMI 2.0, 2x USB-C) and 3 HDMI 2.0 outputs, making it a practical choice for boardrooms and conference rooms requiring dual-screen extended desktop switching with USB peripheral management. AV integrators specifying a Lightware UCX-4x3-HCM40 USB-C dual screen matrix switcher for enterprise collaboration spaces will find it particularly well-suited to Microsoft Teams Rooms and Cisco Room Kit deployments requiring uncompressed 4K video and structured USB routing.

Product Description

The UCX-4x3-HCM40 is part of Lightware's Taurus UCX product family, purpose-built for modern unified communications environments. It enables dual screen extended desktop operation through a single USB-C connection using DisplayPort Alt Mode with multistream transport, providing two independent 4K outputs at 60Hz from a single laptop or mobile device.

Two HDMI 2.0 inputs accept sources from room-installed devices such as codecs, PCs, or display processors, while the two USB-C inputs handle laptop connections with simultaneous video, audio, USB data, and up to 100W power delivery over a single cable. The three HDMI 2.0 outputs can drive displays, video walls, or additional switchers at up to 4K@60Hz 4:4:4.

USB 3.1 Gen1 switching allows cameras, speakerphones, and touch devices to follow the active host automatically. Gigabit Ethernet, GPIO, RS-232, and an occupancy sensor port provide full room automation capability. Active noiseless cooling keeps the unit quiet in occupied spaces. Remote Syslog (RFC3164/RFC5424) supports integration with SIEM platforms. A FIPS 140-3 certified variant (SKU 91360031) is available for government and high-security deployments.

Frequently Asked Questions

Can the UCX-4x3-HCM40 drive two separate displays from a single MacBook Pro?

Yes. The device uses DisplayPort Alt Mode with multistream transport over USB-C, which allows a single USB-C connection from a compatible MacBook or Windows laptop to extend the desktop across two independent HDMI 2.0 outputs simultaneously at up to 4K@60Hz each.

Does the USB-C input charge the laptop while in use?

Yes. Each USB-C input supports up to 100W power delivery, so laptops charge during the meeting without requiring a separate wall adapter.

How is USB peripheral switching handled when a new presenter connects?

The UCX-4x3-HCM40 has an independent USB 3.1 Gen1 switching layer. Cameras, speakerphones, and touch monitors connected to the USB-A device ports can be routed to whichever USB-C or USB-B host is currently active, either automatically on signal detection or via control system command.

Is this device compatible with Microsoft Teams Rooms and Cisco RoomOS?

Yes. Lightware has published verified integration guides for both MTR and RoomOS environments. The device has been tested with Cisco Room Kit EQ, Room Kit Pro, and Room Kit Plus for dual-screen BYOD/BYOM operation.

What control system protocols does the UCX-4x3-HCM40 support?

The device is controlled via the LW3 protocol over TCP/IP (GbE Ethernet port), RS-232 (3-pole Phoenix), and GPIO. It is compatible with Crestron, Extron, AMX, and other third-party control systems that support serial or TCP command sets.

Is a government or high-security version available?

Yes. The UCX-4x3-HCM40-LCC variant includes NIST FIPS 140-3 certified cryptography via Lightware's LWR CryptoCore, suitable for government and regulated enterprise installations.

Where can I purchase the Lightware UCX-4x3-HCM40?

The UCX-4x3-HCM40 is available for purchase at Creation Networks, an authorized Lightware reseller specializing in commercial AV systems.
