Description

System positioning and target users
This controller is designed specifically for integrators, system engineers and AV consultants working in enterprise, education, government, commercial display, digital signage and monitoring venues. It serves as a core component from an established OEM/ODM manufacturer, enabling deployment of a dedicated video wall controller solution or functioning within a broader HDMI Matrix system architecture. Its flexible 2×2 or 1×4 splicing layouts allow panel-based video wall setups or extended single-row display arrays, giving professionals the means to deliver high-end display infrastructures with efficiency.

Technical features and key parameters
The unit supports 4K at 60Hz input resolution with HDR pass-through, ensuring high fidelity and clarity. It provides multiple output modes, enabling either a 2-by-2 video wall layout or a 1-by-4 tile configuration depending on the environment’s needs. Control is provided via front panel, IR and RS-232 (and optionally LAN) for integration into central control systems typical of large-scale AV deployments. It also supports bezel-adjustment/splicing, output resolution scaling and robust signal management, making it suitable for use as a Video Wall Processor within demanding display chains. 

Industry usage and application value
In education or corporate briefing rooms it enables seamless switching of single or multiple sources onto a 1×4 array of displays, enhancing visual collaboration and clarity. For digital signage in retail or public venues, it offers the ability to display unified large-format content or sequential displays across multiple panels, enabling integrators and audio visual suppliers to deliver compelling visual experiences while simplifying deployment and maintenance.


Advantages

Optimised chassis and configuration flexibility
The controller features a rack-friendly design that supports permanent installation in AV racks common to enterprise and government use. Its architecture accommodates either a 2×2 or 1×4 display layout without requiring additional external splicing hardware, thereby reducing system complexity. The integration of both splicing and output layout control inside a single device means that it fulfills the role of a dedicated video wall controller rather than a simpler switch or splitter, offering added value for system integrators.

Seamless system integration and connectivity
With HDMI-2.0/HDMI-enabled input supporting 4K60 with HDR, this unit fits seamlessly into modern AV infrastructures. It is designed to act either upstream in a HDMI Matrix system—handling entire walls of distributed displays—or downstream as a dedicated display processor. The presence of IR, RS-232 and optional network control interfaces ensures that the controller can be integrated into centralised AV control systems often managed by professional audio visual suppliers. This level of integration reduces the need for multiple independent devices and streamlines configurations.

Optimised performance for professional deployments
Performance-wise, the device ensures minimal latency switching, precise splicing and fine control over output layouts and bezel compensation—critical in mission-critical display environments such as government briefing centres or large collaboration spaces. By reducing the number of boxes required (no separate splitter, separate splicer, separate controller) the total bill-of-materials and maintenance overhead are lowered, providing integrators and end-users with cost savings while maintaining high fidelity visuals and reliable operation.

FAQ


1.How can this controller be integrated into a multi-display architecture?
This unit mounts in standard AV racks and is fed by HDMI sources. It supports 2×2 or 1×4 display layouts natively. It can also be connected upstream or downstream of an HDMI matrix or splitter for broader distribution.

2.What warranty and support are provided?
We provide a 24-month hardware warranty under normal conditions. Technical support is available via our service desk and we provide firmware updates and configuration assistance to our professional partners and audio visual suppliers.

3.What formats and interface standards does it support?
The controller supports HDMI input at 4K@60Hz with HDR. Output layouts are configurable in 2×2 or 1×4 form. It supports control via front panel buttons, IR remote, RS-232 and optional LAN integration.

4.What is the lead time for bulk or customised orders?
Standard units ship in approximately 4-6 weeks. For OEM/ODM configurations (custom firmware, branding, special I/O) lead time may extend to 8-12 weeks depending on volume and specification.

5.How is signal integrity and security handled in sensitive applications?
All video routing and splicing occurs within the hardware chassis. It is designed for professional installations where signal integrity is critical. For installations requiring encryption or secure control, customised firmware and secure control interfaces can be arranged via our OEM/ODM offering.
