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

No Signal/Display Issues:
- Ensure all VGA cables are securely connected to both the KVM switch and the computers/monitor.
- Verify that the correct input source is selected on your monitor.
- If a computer starts but you are not on its channel, the resolution might be incorrect. Try unplugging and replugging the VGA cable to that PC, or restart the computer while on its channel.
Keyboard/Mouse Not Working:
- Ensure the USB cables from the KVM switch are securely connected to the USB ports on your computers. The KVM switch is powered via these USB connections.
- Try connecting the keyboard and mouse directly to the computer to confirm they are functional.
- Update USB drivers on your computer if issues persist after weeks of performance.
- Ensure you are not using a Bluetooth keyboard/mouse without a dongle, or a mechanical keyboard/mouse, as these may have compatibility issues.
Switching Issues:
- Confirm you are pressing the correct button for the desired PC.
- This KVM switch is a manual switch and does not support hotkey switching.
Intermittent USB Disconnects:
- Ensure the USB pigtail from the KVM cable is firmly connected to the computer to ensure stable power and data transfer.
- Try connecting the KVM to different USB ports on your computer.
