4. Operating Instructions
4.1 HDMI Display Output
Once connected, your operating system should automatically detect the external display. You can configure display settings (mirror, extend, resolution) through your device's display settings.
- Ensure your host device's USB-C port supports video output (DisplayPort Alternate Mode).
- For optimal 4K@60Hz performance, use a high-quality HDMI 2.0 or newer cable.
4.2 USB Data Transfer
Plug your USB devices into the appropriate ports. The USB-C 3.2 and USB-A 3.2 ports offer speeds up to 10Gbps, ideal for external hard drives and flash drives. The USB-A 2.0 ports are suitable for keyboards, mice, and other standard peripherals.
4.3 Ethernet Connection
Connect an Ethernet cable from your router or modem to the hub's Gigabit Ethernet port. Your device should automatically establish a wired network connection, providing a stable internet experience.
4.4 Power Delivery (PD)
Connect a USB-C power adapter to the hub's 'PD 100W' port. This will charge your connected laptop while the hub is in use. The hub reserves 15W for its own operation, delivering up to 85W to your laptop. Ensure your power adapter is sufficient for your laptop's charging requirements plus the hub's operation.
5. Maintenance
- Cleaning: Disconnect the hub from all power sources and devices before cleaning. Use a soft, dry cloth to wipe the surface. Avoid liquid cleaners or abrasive materials.
- Storage: Store the hub in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Handling: Avoid dropping the hub or subjecting it to strong impacts.
6. Troubleshooting
- No Display Output:
- Ensure your host device's USB-C port supports DisplayPort Alternate Mode.
- Check all cable connections (USB-C from device to hub, HDMI from hub to display).
- Try a different HDMI cable or display.
- Restart your host device.
- Slow Charging or No Charging:
- Ensure your USB-C power adapter is connected to the hub's 'PD 100W' port and is powerful enough for your laptop (e.g., 65W or 100W).
- Verify the USB-C cable connecting the hub to your laptop supports power delivery.
- Some laptops may require specific power adapters; consult your laptop's manual.
- USB Devices Not Detected:
- Ensure the hub is securely connected to your host device.
- Try connecting the USB device directly to your host device to confirm functionality.
- Disconnect and reconnect the USB device to the hub.
- Avoid connecting high-power-consumption devices simultaneously without external power to the hub.
- No Internet Connection via Ethernet:
- Check the Ethernet cable connection to both the hub and your router/modem.
- Verify your router/modem is functioning correctly.
- Ensure your device's network settings are configured for a wired connection (usually automatic).
