Frequently Asked Questions

Q: What input sources are compatible with this 2x2 video wall controller?

A: This HDMI video wall controller is compatible with any HDMI or DVI output device, including DVD players, TV boxes, Xbox consoles, Roku devices, laptops, desktop computers, and more. Simply connect your source to the single HDMI/DVI input and distribute the signal to up to 4 displays.

Q: Why is there no audio output from my video wall processor?

A: Audio output requires that both your input and output devices are set to 1080P resolution. Once the resolution is correctly set, the updated firmware supports audio output to any compatible TV, speaker, soundbar, or amplifier via the 3.5mm stereo jack or optical SPDIF port.

Q: Can I use the 180° rotation feature in all display modes?

A: No — the 180° screen rotation feature is only available in 2×2 mode and requires all connected displays to be running at a resolution no higher than 1080P@60Hz. If your screens are set to 4K, please switch them to 1080P first to enable this feature.

Q: How do I switch between display modes on this video wall controller?

A: You can switch between the 8 available display modes (2×2, 1×1, 1×2, 1×3, 1×4, 2×1, 3×1, 4×1) using the included IR remote control or by pressing the "Switch" button directly on the unit. For advanced automation environments, RS-232 control is also supported.

Q: Is the IR remote control not working — what should I check?

A: The IR remote control operates reliably when both the input source and output displays are set to 1080P resolution. Please verify the resolution settings on all connected devices and ensure you are within range of the IR receiver on the controller unit.
