Operating Instructions
Switching Methods:
The Yinker 4K HDMI Multiviewer offers two convenient methods for switching between inputs and display modes:
- Panel Button: Use the CH1-CH4 buttons on the front panel to directly select an input, or the MODE button to cycle through display modes.
- IR Remote Control: Use the included IR remote control for full functionality, including direct input selection and mode switching. Ensure the remote is pointed towards the IR receiver on the front panel.

Image: This image highlights the two primary switching methods for the multiviewer: the physical buttons on the device's front panel (CH1, CH2, CH3, CH4, MODE) and the included IR remote control, demonstrating ease of use.
Display Modes:
The multiviewer supports four distinct display modes to suit various needs:
- Single Mode: Displays one selected HDMI input source in full screen. Use the CH1-CH4 buttons or corresponding remote buttons to select the desired input.
- Quad Mode: Displays all four HDMI input sources simultaneously on the screen, each occupying a quarter of the display area.
- Dual Mode: Displays two selected HDMI input sources side-by-side.
- PBP Mode (Picture-by-Picture): Displays one main HDMI input source in a larger window, with three other input sources displayed in smaller windows.

Image: This visual guide illustrates the four distinct display modes available on the Yinker 4K HDMI Multiviewer 4x1: Single Screen Mode (full display of one source), Quad Screen Mode (four sources equally divided), Dual Screen Mode (two sources side-by-side), and PBP Mode (one large source with three smaller ones).
Press the MODE button on the front panel or the remote to cycle through these display modes. Audio output will typically follow the main or selected input in multi-view modes. Refer to the remote control diagram in the user manual for specific button functions.
Seamless Switching:
The multiviewer features seamless switching between inputs, minimizing black screen delays when transitioning from one source to another in single mode. This ensures a smooth viewing experience.
