Lightware UMX-HDMI-140 UMX Series Switcher for VGA, DVI-I, HDMI and DisplayPort with Audio embedding - 91560001

Product Overview

The Lightware UMX-HDMI-140 is a four-input multi-format presentation switcher that accepts VGA, DVI-I, HDMI, and DisplayPort sources in a single compact chassis, making it well-suited for conference rooms and training facilities where legacy and modern sources coexist. The unit outputs a unified HDMI signal with embedded audio, removing the need for separate audio de-embedders or format converters. With auto-switching, RS-232, and LAN control built in, the UMX-HDMI-140 integrates directly into managed AV systems without additional control hardware.

Product Description

Modern meeting rooms rarely have a uniform set of source devices. The UMX-HDMI-140 addresses this by accepting four different video formats — VGA, DVI-I, HDMI, and DisplayPort — on dedicated inputs and switching between them to a single HDMI output. The internal scaler normalizes all inputs to a consistent output resolution, eliminating the display-compatibility issues that arise when mixing analog and digital sources.

Audio embedding consolidates analog and digital audio from each source into the HDMI output stream, so a single cable carries both video and audio to the display or audio DSP. The front-panel input selector allows manual switching without a control system, while RS-232 and LAN ports enable full integration with Crestron, AMX, and Extron control systems. Auto-switching detects active sources and switches automatically when a new device is connected, reducing the need for presenter training.

The UMX-HDMI-140 is managed via Lightware's LW3 protocol and Device Controller software, and is available from Creation Networks, an authorized Lightware dealer in North America.

Key Features

• Four-input multi-format switching — VGA, DVI-I, HDMI, and DisplayPort accepted on dedicated inputs in a single chassis
• Single HDMI output — normalized output simplifies cabling to displays, projectors, and HDBaseT transmitters
• Integrated audio embedding — analog and digital audio from each input is embedded into the HDMI output stream
• Internal scaling — converts all input resolutions to a consistent output resolution set by the administrator
• Auto-switching — detects newly connected active sources and switches automatically, reducing presenter interaction
• Front-panel input selection — manual source selection without a control system for simple installations
• RS-232 and LAN control — integrates with Crestron, AMX, Extron, and other third-party control platforms
• LW3 protocol — Lightware's open API for detailed status monitoring and control
• Compact 1U chassis — fits in standard AV racks with minimal space consumption

Typical Applications

• Conference rooms where presenters bring laptops with VGA, HDMI, or USB-C/DisplayPort adapters
• Training rooms with a mix of fixed PCs (VGA/DVI) and visiting presenter laptops (HDMI/DP)
• Boardrooms requiring a unified source switcher feeding an HDBaseT transmitter or display
• Huddle rooms where a simple auto-switch presentation switcher replaces a complex matrix
• University seminar rooms with legacy podium PCs and modern BYOD connectivity

Frequently Asked Questions

Can the UMX-HDMI-140 accept a VGA source with audio?

Yes. Each input has a dedicated 3.5mm analog audio input, so VGA sources with separate audio cables are fully supported. The audio is embedded into the HDMI output.

What output resolution does the switcher produce?

The internal scaler can be set to output up to 1920x1200 or 1080p@60Hz. The output resolution is configured via the control interface and applied regardless of source resolution.

Does auto-switching work when multiple sources are connected?

Auto-switching activates when a new source is detected. Priority order can be configured via the control interface to determine which source takes precedence when multiple sources are simultaneously active.

Is the unit compatible with Crestron control systems?

Yes. The UMX-HDMI-140 supports RS-232 and LAN control using Lightware's LW3 protocol. Crestron drivers are available, and the open protocol allows integration with any control system capable of TCP/IP or serial communication.

Can the HDMI output feed an HDBaseT transmitter?

Yes. The HDMI output is a standard HDMI signal compatible with any HDBaseT transmitter, including Lightware's TPS extender series.

Does the switcher support 4K sources?

The UMX-HDMI-140 is designed for 1080p/1920x1200 workflows. For 4K switching requirements, Lightware offers separate 4K matrix and switcher products.

Where can I purchase the UMX-HDMI-140?

The UMX-HDMI-140 is available from Creation Networks, an authorized Lightware dealer serving commercial AV integrators throughout North America.
