The HDMI & DVI Video Wall Controller is designed to distribute a single HDMI or DVI video source across up to 4 HDMI displays, allowing multiple screens to work together as one large video wall.

It supports 4K input up to 3840 × 2160 @ 30Hz and provides up to 1920 × 1080 Full HD output at 60Hz per screen.

With multiple video wall configurations, bezel compensation, 180° rotation support in selected modes, remote control, and HDMI/DVI connectivity, it is ideal for digital signage, exhibitions, shopping malls, control rooms, conference displays, entertainment systems, and commercial installations.

• 3×1
• 4×1

This provides flexibility for different multi-screen installations and video wall layouts.

4K Input & Full HD Output

The controller accepts HDMI input resolutions up to:

3840 × 2160 @ 30Hz

The video signal is processed and distributed to the connected displays with output resolution up to:

1920 × 1080 @ 60Hz per screen

Important

The 4K specification refers to the input signal only.

The controller does not output 4K resolution to each individual display. Maximum output resolution is 1080P Full HD per screen.

HDMI & DVI Input

The controller can receive video from a wide variety of HDMI or DVI sources, including:

• Desktop computers
• Laptops
• Media players
• TV boxes
• Game consoles
• DVD/Blu-ray players
• Digital signage players
• Security systems
• Other compatible HDMI/DVI devices

The selected input is then processed and divided across the connected HDMI displays.

Bezel Compensation

Bezel compensation helps improve the appearance of an image spread across multiple displays.

It compensates for the physical borders between screens, helping create a more natural-looking continuous image across the complete video wall.

180° Rotation

The controller supports 180° image rotation under specific configurations.

Important: 180° rotation is supported only under 2×2 video wall mode for the first-row displays and when operating at 1080P resolution.

The controller does not support 90° image rotation.

Therefore, it is intended primarily for horizontal/landscape display installations and is not suitable for video walls requiring portrait-mode screen rotation.

Audio Support

The controller supports:

PCM 2-Channel Stereo Audio

Audio can be available through the supported audio output connections, including AUX or digital optical/TOSLINK depending on the unit configuration.

4K Audio Note

In some configurations, audio may not be available when using a 4K @ 30Hz input signal.

If this occurs, set the source resolution to 1080P.

Technical Specifications

HDMI Cable Recommendation

For reliable operation, use good-quality HDMI cables with all 19 pins properly wired and shielded.

Poor-quality or excessively long HDMI cables can cause:

• Signal loss
• Screen flickering
• Synchronization problems
• Intermittent display
• Resolution detection problems

For multi-screen installations, using good-quality cables on all four outputs is particularly important.

Important Notes

1. 4K Input Only:
The controller supports input signals up to 4K @ 30Hz, while the maximum output resolution is 1080P @ 60Hz per display.

2. Use Quality HDMI Cables:
For stable video transmission, use properly shielded, high-quality HDMI cables.

3. Rotation Limitation:
180° rotation is available only under specific 2×2 / 1080P configurations.

4. No 90° Rotation:
Portrait/vertical video wall configurations requiring 90° image rotation are not supported.

5. Audio:
PCM 2-channel stereo audio is supported. If audio is unavailable with a 4K @ 30Hz input, try changing the source resolution to 1080P.

The 2×2 / 1×4 HDMI & DVI Video Wall Controller provides a practical way to transform up to four HDMI displays into a synchronized multi-screen video wall for commercial displays, digital signage, monitoring systems, presentations, and entertainment applications
