2x2 4K Video Wall Controller

This YINGHUA unit splits a single HDMI or VGA source across four HDMI displays in a 2-by-2 grid. It is built for installers and operators who need a large combined image wall for signage, control rooms or presentation spaces without a dedicated graphics card.

Installation notes and common issues

Connect the source with a standard HDMI cable up to 10 metres AWG24 and run four output cables of the same length and gauge to the screens. Power the device from the included 5 V DC 1 A adapter on 100-240 V AC. The remote requires a separate battery. A frequent mistake is forgetting to set the input resolution to 4K at 30 Hz or lower, which the scaler cannot exceed.

Capacity and headroom

The controller accepts 4K30, 1080p, 1080i, 720p, 576p, 576i or 480p input and down-scales each quadrant to 1080p, 1080i, 720p, 576p, 576i or 480p output. It handles eight splicing layouts including 1x3, 3x1, 1x4 and 4x1, and rotates the top two panels 180 degrees in 2x2 mode. It cannot pass native 4K to each screen, output higher than 1080p, or support more than four displays.

Questions about this item

How do I verify the 2x2 video wall is displaying the 4K input correctly after connecting four HDMI screens?

Each of the four HDMI outputs should show one quarter of the source image at 1080P; use the remote to confirm the 2x2 automatic splicing mode is active and the top two displays are rotated 180° if that layout is selected.

Which cables and accessories are included and what must I provide myself?

The box contains the controller, a 5V DC 1A power adapter with AU plug, a remote control without battery and a user manual; you must supply HDMI cables for the input and four outputs and a battery for the remote.

When should I choose the 2x2 mode versus the 1x3, 3x1, 1x4 or 4x1 splicing modes?

Select 2x2 for a square four-screen wall with optional 180° rotation on the top row; choose 1x3 or 3x1 for three-screen horizontal or vertical strips, and 1x4 or 4x1 for four-screen single-row or single-column layouts.
