BẢO TRÌ

The KVM switch is designed for reliable operation with minimal maintenance. Keep the device in a clean, dry environment. Avoid exposing it to extreme temperatures or humidity. Do not attempt to open the casing or repair the device yourself, as this will void the warranty.

To clean the device, use a soft, dry cloth. Do not use liquid cleaners or aerosols.

Xử lý sự cố

• Màn hình không hiển thị hoặc nhấp nháy:
  • Ensure all HDMI and DisplayPort cables are securely connected.
  • Verify that the KVM switch is powered on and the correct input is selected.
  • Check if your monitors and graphics cards support the selected resolution and refresh rate (e.g., 4K@60Hz).
  • Using high-quality, shorter HDMI/DP cables (e.g., 8K certified cables) can help resolve flickering or black screen issues, especially at higher resolutions.
  • For laptops, ensure the USB-C port is a full-function port supporting video output.
• Bàn phím/Chuột không hoạt động:
  • Ensure the USB 3.0 cable from your desktop PC is connected to the KVM switch's USB3.0 input.
  • For laptops, ensure the USB-C cable is properly connected and supports data transfer.
  • Try connecting the keyboard/mouse directly to the computer to confirm they are functional.
  • Reconnect the USB peripherals to the KVM switch.
• Máy tính xách tay không sạc được:
  • Ensure your laptop's Type-C charging cable is connected to the KVM switch's PD cảng.
  • Xác minh rằng cổng USB-C của máy tính xách tay của bạn có hỗ trợ Power Delivery không.
  • The KVM switch provides up to 60W. If your laptop requires higher wattage, it may charge slower or display a warning.
• Mac OS Laptop Outputs Identical Screens:
  • Mac OS typically does not support Multi-Stream Transport (MST) for extending displays via a single USB-C connection to multiple external monitors. Therefore, Mac OS laptops will usually output two identical screens (mirror mode) when connected to this KVM switch. This is a limitation of Mac OS, not the KVM switch.
