2x2 4k Video Wall Controller, Transform 4 TV Screens into a Single Wall Display with HDMI & DVI 4K Input, 180° Rotation, Audio Output, IR Remote/RS232/Button Press Control

2x2 4K video wall controller supports HDMI or DVI input and has 4 HDMI outputs. Its core function is to split a complete HDMI or DVI 4K image signal into 4 HDMI outputs for display on devices like rear - projection units and LCD TVs. This allows you to combine 4 TV screens into one large dynamic image wall.
Each channels HDMI output supports various resolutions including 1920*1080, 1280x800, etc., and the input can support a resolution up to 4K@30Hz (DVI does not support 4K).
This TV wall controller offers 11 different splicing modes, such as 2x2, 1x2, 1x3, 1x4, 2x1, 3x1, 4x1, and a 1x1 HDMI splitter mode. It has a vertical splicing function. When using a PC as input and rotating the desktop portrait, you can set portrait modes 1x2, 1x3, 1x4, but need to select corresponding horizontal modes for the desired portrait display. All modes are easily controlled via hotkeys on the remote or button presses.
The 2x2 video wall controller supports IR remote control, RS232 control, and button - press control. The remote has commonly used modes for direct operation. Moreover, it has a memory function, remembering the last settings when plugged in again, ensuring a seamless experience
The controller provides highly flexible screen rotation capabilities. It allows each single screen can be rotated by 180 degrees. The 180 degree rotation function for HDMI output 1 and output 2 (available only in 2x2 mode) helps adjust the screens to minimize the thick middle border. The edge mask function corrects and aligns bezels and image edges, making the multi - screen display more visually appealing.
It comes with an individual 3.5 mm stereo audio port for connecting external speakers, amplifiers, or sound bars. Even without an external audio connection, there will still be audio from the HDMI output.
The video wall controller features a smart chip with a plug - and - play design, no drivers required. It is easy to operate and widely compatible with various HDMI and DVI input and output devices.
