Product Overview
What makes the ML-401 HMVS-4K
The ML-401 HMVS-4K consolidates multiple HDMI sources into a single HDMI output display. Instead of deploying separate monitors for each source, the device enables simultaneous viewing through configurable screen layouts, improving monitoring efficiency while optimising display infrastructure.
In commercial AV deployments, multiview capability is particularly useful in surveillance monitoring, presentation environments, and technical control setups where operators need visibility across multiple content feeds simultaneously. The device manages signal processing internally and outputs a unified display without requiring external software or host system involvement.
With 4K@30Hz output support, the system ensures that screen clarity is maintained even when multiple sources are displayed within the same layout. This makes it equally suitable for precision monitoring tasks and high-visibility presentation environments where image quality across all input feeds is critical.
Because the ML-401 HMVS-4K operates independently of operating systems, it integrates seamlessly into enterprise AV installations managed by system integrators and IT teams, with no configuration overhead or driver management required after deployment.

Installation
Simple setup. No software required.
The ML-401 HMVS-4K is designed for straightforward deployment within structured AV systems. Installation involves connecting source devices, routing the output to a display, and powering the unit. No drivers, configuration software, or technical calibration are required.
01
Connect HDMI Source Devices
Plug the required HDMI source devices into the available input ports on the ML-401 HMVS-4K. Sources may include computers, media players, cameras, or any HDMI-enabled equipment intended for simultaneous monitoring on the display.
02
Route HDMI Output to the Display
Connect the single HDMI output from the unit to a 4K-capable display, monitor, or screen. The device processes all connected source signals and delivers a unified multiview output to this single display.
03
Power On the Unit
Once powered, the device automatically manages signal processing and displays connected sources in the default layout. No configuration, driver installation, or software setup is needed before operation begins.
04
Select Layout via Remote Control
Use the included remote control to switch between available layout modes including full-screen, split-screen, and quad-view. Source selection and layout changes are applied instantly without interrupting the display feed.
Designed for real-world AV environments
The ML-401 HMVS-4K is deployed across professional settings where multiple HDMI sources must be monitored or presented on a single display without additional screen infrastructure.
Control Rooms
Monitors multiple HDMI feeds on a single 4K display for operational visibility and centralised control, reducing the need for multiple screens while maintaining clear source visibility across all input channels.
Corporate Boardrooms
Displays multiple presentation sources simultaneously during meetings and collaborative sessions, allowing participants to reference different content streams on a single screen without switching between full-screen views manually.
Security and Surveillance Monitoring
Enables operators to view multiple camera feeds simultaneously on one screen without deploying multiple monitors, simplifying surveillance station infrastructure and improving response capability through consolidated visual coverage.
Training and Technical Facilities
Enables instructors and operators to compare multiple content sources within a unified display environment, supporting side-by-side reference and multi-source instruction without managing separate display hardware for each feed.

Frequently asked questions
What is the purpose of the ML-401 HMVS-4K HDMI Multiviewer?
The ML-401 HMVS-4K allows multiple HDMI source devices to be displayed simultaneously on a single screen using different layout modes. It simplifies monitoring and presentation setups by eliminating the need for multiple displays, and outputs a unified view at 4K resolution through a single HDMI connection.
Does this multiviewer support 4K@30Hz resolution output?
Yes, the device supports 4K output resolution, ensuring screen clarity even when multiple sources are shown within the same layout. This allows all sources to remain clearly visible and readable regardless of the selected display arrangement.
Can users change layouts and switch sources easily?
Yes, the included remote control allows users to switch between layout modes and manage sources conveniently without accessing the device directly. This makes the multiviewer practical for rack-mounted installations and operator-controlled environments where device access is limited.
Where is the ML-401 HMVS-4K commonly used?
It is commonly used in control rooms, corporate boardrooms, surveillance monitoring stations, digital signage systems, and training facilities where multi-source visibility is required on a single display. It is designed for professional AV environments where multiple HDMI feeds must be managed and viewed concurrently.
