4. Setup Instructions

Follow these steps to set up your RIJER RJ-UD12 Video Wall Controller.

1. Prepare Displays: Position your two displays (TVs or monitors) side-by-side to form the desired 1x2 video wall configuration. Ensure they are powered off.
2. Connect Input Source:
   • Connect your source device (e.g., laptop, PC, media player) to one of the input ports on the RJ-UD12 (HDMI-1, HDMI-2, or DP) using a high-quality HDMI or DisplayPort cable. For optimal performance with 4K signals, fiber optic HDMI cables are recommended.
   • Note: HDMI-1 supports HDMI2.0 (3840x2160@60HZ), HDMI-2 supports HDMI1.4 (3840x2160@30HZ), and DP supports DP1.2 (3840x2160@60HZ).
3. Connect Output Displays:
   • Connect the two HDMI output ports of the RJ-UD12 to the HDMI input ports of your two displays using high-quality HDMI cables.
4. Connect Audio (Optional): If you require separate audio output, connect speakers or an audio system to the 3.5mm Audio Out jack on the RJ-UD12.
5. Connect IR Receiver: Plug the IR Receiver Cable into the "External" port on the RJ-UD12. Position the IR receiver in a location where it can receive signals from the remote control.
6. Power On: Connect the DC 12V Power Adapter to the "DC 12V" port on the RJ-UD12, then plug the adapter into a power outlet. The device will power on automatically.
7. Power On Displays: Turn on your two connected displays.
8. Select Input: Use the buttons on the front panel or the remote control to select the appropriate input source (HDMI1, HDMI2, or DP).

7. Troubleshooting

If you encounter issues with your RIJER RJ-UD12, please refer to the following common problems and solutions:

• No Signal on Displays:
  • Ensure all HDMI/DP cables are securely connected to both the source device, the RJ-UD12, and the displays.
  • Verify that the correct input source is selected on the RJ-UD12 (HDMI1, HDMI2, or DP) and on your displays.
  • Check if the source device is powered on and outputting a signal.
  • Try using different, high-quality HDMI/DP cables, especially for 4K signals.
  • Restart the source device, the RJ-UD12, and the displays.
• Image Flickering or Instability:
  • Ensure all cables are high-quality and properly shielded. Inferior cables can cause signal degradation.
  • Check the resolution and refresh rate settings of your source device. Ensure they are within the supported range of the RJ-UD12 and your displays.
  • Verify that the power adapter is securely connected and providing stable power.
• No Audio Output:
  • Confirm that your source device is outputting audio.
  • If using the 3.5mm Audio Out jack, ensure your speakers or audio system are properly connected and powered on.
  • Check the audio settings on your source device and displays to ensure audio is routed correctly.
  • The RJ-UD12 provides a dedicated 3.5mm audio output. If you expect audio through the HDMI outputs, ensure your displays support audio passthrough from the HDMI input.
• Remote Control Not Responding:
  • Ensure the IR Receiver Cable is securely plugged into the "External" port and positioned to receive signals from the remote.
  • Check the batteries in the remote control and replace them if necessary.
  • Ensure there are no obstructions between the remote and the IR receiver.
• Image is Stretched or Distorted:
  • Ensure your source device is outputting a resolution of 3840x1080@60HZ when in 1x2 mode to avoid stretching.
  • Check the display settings on your monitors/TVs to ensure they are set to "Just Scan" or "1:1 Pixel Mapping" to prevent overscan or scaling by the display itself.
