The HDMI video wall is a simple four-screen splicing processor that enables four-screen splicing or single-screen display with one button. It adopts unique embedded hardware design, can accept various image signal source input and is divided, amplified, real-time distortion-free HDMI output, the process is completely hardwareized, no need for computer and startup software, it is very simple. The basic function is to divide and enlarge the externally input HDMI signal into a full-screen image, and then output the splicing display directly to the terminal display device from the four HDMI outputs.

The MT-VIKI’s HDMI video wall can support input screen splicing and picture non-splicing mixed mode. Display on different screens at the same time, customers can combine them into any splicing scheme to display by cascading mode.

The HDMI image splicing processor adopts cutting-edge processing techniques such as motion detection and compensation calculation, interpolation operation, edge smoothing processing and clutter signal suppression. The screen after splitting has no delay, no smearing, smoothness and clear picture quality.
