3x3 Video Wall Controller

The YINGHUA 3x3 video wall controller splits one HDMI or DVI source across nine HDMI displays. It accepts 4K signals at 30 Hz and outputs 1080p at 60 Hz per screen. The unit is designed for control rooms, signage installations and multi-monitor workstations that need a single large canvas.

Replaces matrix switchers and software splitters

Hardware slicing removes the latency and driver dependence of PC-based solutions. The jump is worth it when you need guaranteed 60 Hz output on every panel without a dedicated graphics card per display. It also removes the need for a host computer to stay powered on.

Check source resolution and cable quality

The controller only accepts 1920x1080 at 25, 30, 50 or 60 Hz and 3840x2160 at 24 or 30 Hz. Verify your source matches one of these formats before ordering. Use fully wired 19-pin HDMI cables and a stable 12 V 2 A supply; the package includes a US-plug adapter and an IR remote without batteries.

Questions about this item

What input connectors and cable type does the 3x3 video wall controller require for the source signal?

It accepts one HDMI 1.4 or DVI input. Use a qualified HDMI cable with all 19 pins wired and shielded to avoid sync issues.

How do I configure the 3x3 splicing mode and which step is commonly missed?

Connect the source to the HDMI or DVI input, link nine displays to the HDMI outputs, set the input to 1920x1080P at 60 Hz or 3840x2160P at 30 Hz, then select 3x3 mode via the remote or RS232; the step often missed is setting the source to a supported refresh rate before powering on.

What ongoing maintenance does the controller need and which consumable is not included?

No internal maintenance is required; the only consumable is a battery for the remote control, which is not supplied in the package.
