Important Notes for Setup:

• Ensure each computer supports dual-monitor display. Test by connecting monitors directly to your computer before using the KVM switch.
• Each computer requires one DisplayPort cable and one USB-A cable connected to the KVM switch for full functionality (video, keyboard, mouse).
• Both your computer and monitors must support 4K@60Hz, and you must use appropriate cables, to achieve 4K@60Hz resolution.
• Do not press the switch button while connecting devices or cables to prevent potential issues.
• The two monitors will display the video source from only one computer at a time; simultaneous output from both PC1 and PC2 is not supported.

Display Working Modes

The KVM switch supports two primary display modes for your dual monitors:

• Extended Mode: Each monitor displays a different part of your desktop, extending your workspace.
• Mirror Mode: Both monitors display the same content, mirroring your desktop.

To configure display modes on Windows, press Win + P and select your desired mode (Duplicate or Extend). For macOS, please note that Multi-Stream Transport (MST) for extended mode may not be fully supported, depending on your Mac model and OS version.

7. Troubleshooting

If you encounter issues with your KVM switch, please refer to the following common solutions:

• No Display / Flickering Screen:
  • Ensure the 5V power adapter is securely connected to the KVM switch and a power outlet.

  • Try connecting the keyboard and mouse to different USB ports on the KVM switch.
  • Ensure the correct computer input (PC1 or PC2) is selected on the KVM switch.
  • Note that hotkey switching is not supported; use the physical button on the KVM or the wired desktop controller.
• USB Devices Not Detected:
  • Confirm the USB-A to USB-A cables are properly connected from both computers to the KVM switch.
  • Ensure the KVM switch is powered on.
  • Try connecting the USB device to a different USB 3.0 port on the KVM switch.
• Audio Issues:
  • Check the audio cable connection from your speakers/headphones to the KVM's Audio Out port.
  • Verify audio output settings on your computer are configured to use the KVM switch as the audio device.
