What is a video wall?

Video wall is a large-scale system of multiple displays that are combined into a single seamless plane for broadcasting images or video. It allows you to create a large, clear and bright screen that provides effective information in large spaces. Thanks to its modular structure, the video wall can be scaled to fit any format, both standard and non-standard.

How a video wall works

Each panel displays a part of the overall image synchronised via a video controller or special software. The screens are placed with a minimum gap between them — up to 0.88 mm, this creates the effect of a single plane. The signal can come from a computer, camera, video server, video surveillance systems or online platforms.

Types of video walls by construction principle

• LCD panels — liquid crystal displays with thin bezels. Most often used indoors. Relatively affordable, with high resolution.
• LED panels — LED modules without seams. They are suitable for large areas, work well in outdoor lighting, and are easily scalable.
• Video cubes — projection solutions for situation centres or control rooms. They are highly detailed but require more space.

Popular configurations

Among the basic configurations of video walls:

• 2×2 — a compact solution for meeting rooms, small halls, and training spaces.
• 3×3 — a universal format for shopping malls, conference halls and museums.
• 4×4 — large-format design for spacious rooms, showrooms, situation centres.

These systems can be easily expanded or adapted to non-standard geometries, including vertical, panoramic or curved shapes.

Video wall installation: stages and features

Correct installation is critical to the quality of the display and the reliability of the system. Installation work is carried out in stages:

1. Selection of the installation method: depending on the space available, the video wall can be mounted on the wall, floor, suspended structures or a combination. It is important to take into account the load and accuracy of the location.
2. Installation of mounts and displays: the screens are installed as close together as possible. Gaps are minimised by using special mounting frames.
3. Connecting the signal and power supply: all panels are connected to content sources and power supply via controllers that synchronise the display.
4. Image calibration: adjusts the brightness, colour temperature, clarity and contrast of all modules to create a uniform picture.
5. Testing the system: the stability of operation, response time and correctness of signal transmission are checked.

A well-mounted video wall ensures long-term uninterrupted operation and ease of further maintenance.

Where video walls are installed

Video wall is an effective tool for visual communication in large-scale spaces. It is used in:

• shopping centres, showrooms, lobbies of business centres;
• airports, railway stations, transport hubs;
• conference halls, museums, exhibition pavilions;
• control rooms, situational and media centres;
• educational institutions, hospitals, government agencies.

Video wall is a flexible solution for large-scale information display. It combines technical reliability, high image quality and space adaptability. Its effectiveness depends on the right type and configuration and precise installation, so it’s important to consider all the technical details at the design and installation stage.
