5. Operating Modes
The ICUIXIAN MP88U supports various operating modes to suit different display requirements.
5.1. HDMI Matrix Mode
In matrix mode, any of the 8 HDMI input sources can be routed to any of the 8 HDMI output displays independently. This allows for flexible signal distribution, where different displays can show different sources, or multiple displays can show the same source.
5.2. Video Wall Mode
The device can be configured to create a video wall using up to 4 output displays (4x2 configuration). This mode allows a single source to be stretched across multiple screens, creating a larger, unified display. Various video wall layouts are supported, including 4x2, 2x4, 3x2, 2x2, 1x2, 2x1, 1x3, 3x1, 1x4, and 4x1. Video wall configurations are typically managed via the Web GUI or RS-232 control.

5.3. Multi-Viewer / Picture-In-Picture (PiP) Mode
The multi-viewer function allows displaying multiple input sources simultaneously on a single screen. The Picture-In-Picture (PiP) feature enables one video source to be displayed as a smaller inset window over another main video source. The device supports screen overlay with up to 4 window roaming, providing dynamic display options.
