Setup
- Verify Laptop Compatibility: Ensure your laptop's USB-C port supports video output (DisplayPort Alt Mode) and Power Delivery if you intend to use these features. Not all USB-C ports are identical. Look for symbols like a lightning bolt (Thunderbolt), a 'D' inside a square (DisplayPort), or a battery icon next to the USB-C port.

- Connect the Hub to your Laptop: Plug the USB-C connector of the MOKiN hub into an available USB-C port on your laptop.
- Connect External Displays: Use HDMI cables to connect your monitors to the HDMI ports on the MOKiN hub.
- Connect Peripherals: Plug in your USB devices (e.g., keyboard, mouse, external hard drive) into the USB 3.1 and USB 2.0 ports on the hub.
- Power Delivery (Optional): If you wish to charge your laptop through the hub, connect your laptop's original USB-C power adapter to the PD port on the MOKiN hub.

Operating Instructions
Display Modes (Windows Laptops)
For Windows laptops, the MOKiN USB C Hub supports both Mirror (SST) and Extend (MST) display modes, allowing for triple display setups (laptop screen + two external monitors).
- Mirror Mode: Duplicates your laptop's screen onto the connected external monitors.
- Extend Mode: Extends your desktop across multiple screens, providing more workspace. Each external monitor can display different content.

Figure 4: Illustration of multiple display modes for Windows systems. It shows both Mirror Mode (duplicating the laptop screen) and Extend Mode (extending the desktop across two external monitors).
To configure display settings on Windows, right-click on your desktop, select "Display settings," and arrange your monitors as desired.
Display Modes (Mac OS Laptops)
Important Note for Mac OS Users: Due to Mac OS limitations, this hub only supports Mirror Mode (SST) for external displays. It does not support extended triple display functionality where each external monitor shows different content. All connected external monitors will mirror the primary display.

Figure 5: Visual representation indicating that MacBooks connected to this hub will only support Mirror Mode for external displays.
Data Transfer
The hub provides high-speed data transfer capabilities:
- USB 3.1 Port: Offers data transfer speeds up to 10Gbps, suitable for external hard drives and high-bandwidth devices.
- USB 2.0 Ports: Provides 480Mbps transfer speed, ideal for connecting standard USB devices like flash drives, keyboards, and mice.

Troubleshooting
- No Display Output:
- Ensure your laptop's USB-C port supports DisplayPort Alt Mode.
- Check all cable connections (USB-C to hub, HDMI to monitors) are secure.
- Try restarting your laptop and reconnecting the hub.
- Test with different HDMI cables or monitors if possible.
- Update your laptop's graphics drivers.
- Flickering or Unstable Display:
- Ensure the resolution and refresh rate settings are within the supported range (e.g., 4K@30Hz for dual HDMI).
- Reduce the resolution of the external monitors to see if stability improves.
- Ensure adequate power supply to the hub and laptop, especially when using multiple high-power devices.
- USB Devices Not Recognized:
- Ensure the hub is securely connected to the laptop.
- Try connecting the USB device directly to the laptop to confirm it functions independently.
- Avoid connecting high-power consumption USB devices simultaneously without external power to the hub.
- Charging Issues (PD Port):
- Ensure your laptop's original USB-C power adapter is connected to the hub's PD port.
- Verify that your laptop supports charging via its USB-C port.
- Check the wattage of your power adapter; it should be sufficient for your laptop and the hub.
- Hub Overheating:
- It is normal for the hub to become warm during heavy use, especially with multiple displays and devices connected.
- Ensure proper ventilation around the hub. Avoid placing it in enclosed spaces.
- If it becomes excessively hot, disconnect some peripherals or displays to reduce load.
