2×2 4K Video Wall Controller

The YINGHUA 2×2 video wall controller accepts one HDMI or VGA source at up to 4K30 and splits the image across four HDMI displays. It supports eight splicing layouts including 1×3, 3×1, 1×4, 4×1 and automatic 2×2 stitching. The unit also provides a 3.5 mm audio output for external speakers.

Build Integration

Four HDMI cables up to 10 metres AWG24 connect the controller to the displays, while the source cable can run the same length. The included 5 V DC 1 A power adapter operates on 100–240 V AC at 50 or 60 Hz, so no separate voltage step-down is required. A handheld remote (battery not supplied) handles layout switching and the 180° rotation of the top-row screens in 2×2 mode.

Sustained Operation

The controller maintains the selected splice mode continuously without dropping frames at the supported output resolutions of 1080p, 1080i, 720p, 576p, 576i and 480p. Passive cooling and the low 5 V power draw allow uninterrupted operation in installed environments. It does not suit installations that require 4K60 output or more than four display endpoints.

Questions about this item

How many displays can I drive continuously before the 1080p output limit becomes the bottleneck?

The unit splits one 4K30 or 1080p source across four HDMI outputs, each capped at 1080p resolution, so the output resolution ceiling is reached as soon as all four screens are active.

Does the 5 V 1 A adapter run warm or audible after hours of 2x2 splicing?

The controller draws only 5 V DC at 1 A from the supplied adapter, with no fan mentioned, so heat and noise stay minimal during all-day operation.

Which cables and sources must I already have to use the 2x2 mode immediately?

You need one HDMI or VGA source, up to 10 m AWG24 HDMI cables for input and each of the four outputs, plus displays that accept 1080p HDMI signals.
