This MT-VIKI 2×2 video wall controller is specially designed for commercial splicing screen display solutions. It expands 2 HDMI signal sources into four synchronized HDMI output channels to form a complete 2-row × 2-column TV wall, realizing large-screen combined playback.

Adopting optimized image processing technology, it delivers non-stretching and non-deforming display effect, effectively avoiding picture extrusion or distortion caused by screen splicing. It supports two core practical functions: point-to-point independent display for playing different content on each screen, and 180° full image rotation to adapt to upside-down installed screens.

Supporting maximum 4K@30Hz resolution and backward compatible with 1080P/720P, it works well with media players, PCs, set-top boxes and other HDMI signal sources. The independent 3.5mm audio extraction port separates stereo audio signals, allowing you to connect external audio equipment without extra wiring.

Compact sturdy metal housing ensures stable long-time continuous operation. Plug-and-play without complicated driver setup, widely used for shopping mall advertising walls, exhibition booth display, office lobby large-screen splicing and monitoring center multi-screen combination projects.
