6. Operating Modes

6.1 HDMI Matrix Mode

In HDMI Matrix Mode, any of the four input sources can be independently routed to any of the four output displays. This allows for flexible content distribution to multiple screens simultaneously.

• Use the front panel buttons, remote control, or RS232 software to select which input is displayed on each output.
• Supports seamless switching between sources without black screens or delays.
• Features a 4-screen preview function to monitor all inputs on a single display.

6.2 Video Wall Mode

In Video Wall Mode, a single input source is stretched across multiple displays to create a larger, unified image. The UD04 supports various splicing configurations and image manipulations.

• Splicing Modes: Supports vertical and horizontal splicing configurations such as 1x4, 4x1, 2x2, 1x3, 3x1, 1x2, and 2x1.
• Image Rotation: Images on individual display units can be rotated by 90, 180, or 270 degrees. This includes reversing the top LCD screen for minimizing gaps in vertical setups.
• Edge Blending/Masking: Corrects image edges to minimize physical frame gaps between displays, ensuring a more natural and life-like vision without blurring or stretching.

9. Troubleshooting

If you encounter issues with your ICUIXIAN UD04 controller, please refer to the following common troubleshooting steps:

• No Signal: Ensure all HDMI cables are securely connected and are of high quality. Verify that input sources are powered on and output displays are set to the correct HDMI input.
• Image Distortion/Flickering: Check cable integrity and ensure all devices support the selected resolution and refresh rate. Try reducing the output resolution if issues persist.
• Control Issues: For remote control, ensure the IR receiver has a clear line of sight. For RS232 control, verify cable connection and software settings.
• Incorrect Splicing: In video wall mode, ensure displays are physically arranged according to the selected splicing mode and that output cables are connected to the correct ports (OUT1, OUT2, etc.) as per the manual's instructions for your desired layout.
