- Extended Mode: Each monitor displays a different part of your desktop, extending your workspace. To activate, press "Windows + P" on your keyboard and select "Extend" in the pop-up window. This allows you to drag windows across all three screens.
- Mirror Mode (Duplicate Mode): All three monitors display the same content. To activate, press "Windows + P" on your keyboard and select "Duplicate" in the pop-up window.
- Splicing Wall Display: This mode allows for advanced configurations, often used for video walls or specific professional applications. Configuration typically depends on your graphics card software.
Note:
- Ensure your PC/laptop graphics card supports triple monitor output before purchasing or setting up.
- MAC M1/M2 chips may not support extended mode due to hardware limitations.
6. Troubleshooting
If you encounter issues with your KVM switch, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display on monitors. | Loose cable connections, incorrect input selection, KVM not powered, graphics card not configured. | Check all HDMI, DisplayPort, and power cables. Ensure the KVM is powered on. Press the select button to ensure the correct PC is chosen. Verify your computer's display settings. |
| Monitors display but USB devices (keyboard/mouse) do not work. | USB A-to-B cables not connected, loose USB connections, KVM not powered. | Ensure the USB 3.0 A-to-B cables are securely connected from each PC to the KVM. Check the connections of your keyboard/mouse to the KVM's USB ports. Ensure the KVM is powered. |
| Resolution is lower than expected (e.g., not 8K/4K). | Cables not supporting high resolution, monitor/graphics card limitations, incorrect display settings. | Ensure all HDMI and DisplayPort cables are rated for 8K/4K. Verify your monitors and graphics card support the desired resolution and refresh rate. Adjust display settings on your computer. |
| Only one or two monitors display. | Missing video cable connections, graphics card limitation, incorrect display mode. | Confirm all 2 DisplayPort and 1 HDMI cables are connected from the PC to the KVM, and from the KVM to the monitors. Ensure your PC's graphics card supports triple monitor output. Check display mode (Extend/Duplicate) settings. |
| KVM switch is unresponsive. | Power issue, temporary glitch. | Unplug and re-plug the power adapter. Try a different power outlet. |
