In the digital information age, massive video walls have become iconic features in command and control centers, commercial displays, entertainment venues, and more. Whether monitoring critical data, displaying advertising content, or creating immersive experiences, video walls play an irreplaceable role. Video wall controllers are the brains behind these dazzling displays.

A video wall controller is a specialized device used to combine multiple display units (such as LCDs, LEDs, or projectors) into a unified visual experience. It receives a variety of signal sources (including HDMI, DVI, and VGA), processes and splits them, and then distributes the content to multiple displays, enabling features such as cross-screen display, window roaming, and overlay effects。

Avideo wall controller's core functions include signal processing, image segmentation, splicing and blending, and color correction, ensuring a seamless, uniform, and color-consistent visual experience。

1. Signal Processing and Resolution Support

Modern 4K video wall controller systems support a wide range of input and output signal formats, delivering resolutions from 1080p to 4K and even 8K. High-performance 4K video wall controller solutions, such as the Bitvisus BIT-MSE-4K60-104PRO, enable multi-unit parallel connectivity and point-to-point splicing without stretching or distortion, ensuring exceptional ultra-high-definition display performance.

2. Bezel Compensation Technology

Advanced video wall controllers feature bezel compensation, adapting to any display bezel width, ensuring accurate image display across multiple displays without visual interruption due to borders.

3. Multiple Windows and Flexible Layouts

Modern controllers support multiple windows on a multi-screen wall, with flexible positioning and resizing. For example, Jupiter's Control 500 supports up to eight windows per output channel, while the Bitvisus BIT-VJ-106Pro supports up to 30 windows simultaneously.

4. Multiple Control Methods

Video wall controllers typically support a variety of control interfaces, including front panel buttons, infrared remote control, RS-232, and IP control (web server interface, Telnet, and UDP), providing flexible operation.

Founded in 2018, Shenzhen Bitvisus Co., Ltd. is a high-tech enterprise specializing in the research and development of core technologies, focusing on FPGA image processing and high-definition audio and video signal transmission. The company boasts extensive product development experience and has obtained numerous patents related to the audio and video industry.

Bitvisus Core Product Series

Bitvisus offers a variety of video wall controllers to meet the needs of diverse application scenarios:

Video Wall Controller, such as the BIT-VWC-409 R, support 4 HDMI inputs, 1 DP input, 9 HDMI outputs, and 1 DP loop-through output. It supports large-scale cascading and parallel operation, as well as various windowing modes.

Multi-Screen Extenders/Multi-Screen Controllers, such as the BIT-MSE-4K60-104HD, utilize a high-end 28nm programmable FPGA chip and a fully hardware-based real-time processing architecture. They support output resolutions up to 4x1920x1200@60Hz, 1xN multi-mode arrangement, and point-to-point display.

Magic splicers, such as the BIT-VJ-106Pro, integrate multiple functions, including 8K/4K/2K playback control, splicing (point-to-point and special-shaped), windowing, 30-layer overlay, roaming, slicing, and edge effects.

UHD audio and video matrices, such as the BIT-Ma-U1-4K60-MC-0808, support switching between eight HDMI inputs and eight HDMI outputs, meeting the input and output needs of a variety of signal sources.
