4. Setup Guide

Follow these steps to set up your UPERFECT Laptop Screen Extender:

  2. Connect Cables:
    • For Laptops with Full-Featured USB-C Ports: Use one USB-C to USB-C cable for each external screen. This single cable can transmit both video signal and power.
    • For Laptops without Full-Featured USB-C Ports: Use one Mini HDMI to HDMI cable for video signal and one USB-A to USB-C cable for power for each external screen. Connect the HDMI cable to your laptop's HDMI port and the Mini HDMI port on the extender. Connect the USB-A end to your laptop's USB port and the USB-C end to the extender's power input.
    • External Power (Optional/Recommended): If your laptop cannot provide sufficient power, or if you wish to charge your laptop via the extender, connect the provided 45W Type-C power bricks to the dedicated power input ports on each external screen.
  3. Power On: Once connected, the screens should automatically power on and display your laptop's content. If not, press the power button on each external screen.
  4. Configure Display Settings: Access your operating system's display settings to arrange the screens (e.g., extend display, mirror display) and adjust resolution or orientation as desired.

5. Operating Instructions

The UPERFECT Screen Extender offers various modes and adjustments for optimal use:

Display Modes:

  • Extended Mode: Each external screen acts as an independent display, expanding your desktop area. This is ideal for multitasking.
  • Mirror Mode: The external screens duplicate your laptop's display, useful for presentations or sharing content.
  • Vertical Mode: Detach one or both screens from the main unit and use their built-in stands to position them vertically. This is beneficial for viewing long documents or code.

Screen Rotation and Swivel:

The screens can be rotated and swiveled to suit your viewing needs:

  • 360° Swivel Hinge: Each external screen can swivel independently around the central hinge, allowing for flexible positioning and easy content sharing with others.
  • 180° Automatic Rotation: The screens feature gravity sensing, which automatically adjusts the display orientation (landscape or portrait) when the screen is physically rotated.

  • Brightness and Contrast
  • Color Temperature and Mode
  • Aspect Ratio (e.g., 16:10, 16:9)
  • Input Source Selection

6. Connectivity

Each external screen is equipped with multiple ports to ensure broad compatibility and functionality:

  • 2 x USB-C Ports: These ports support both video signal transmission and power delivery. One port can be used for full-featured connectivity (video + power), while the other can be used for additional power input or pass-through charging.
  • 1 x Mini HDMI Port: For video input from devices that support HDMI output.
  • Pass-Through Charging: The USB-C ports on the extender can provide up to 60W of pass-through charging to your laptop or other connected devices, reducing the need for multiple power adapters.

7. Maintenance and Care

Proper maintenance ensures the longevity and optimal performance of your screen extender:

  • Cleaning: Use a soft, lint-free cloth slightly dampened with water or a screen-safe cleaning solution to clean the display surfaces. Avoid harsh chemicals or abrasive materials.
  • Storage: When not in use, fold the extender securely and store it in a protective sleeve or bag to prevent scratches and damage.
  • Handling: Always handle the device with care. Avoid applying excessive pressure to the screens or hinges.
  • Environmental Conditions: Do not expose the device to direct sunlight for prolonged periods, high humidity, or extreme temperatures.

8. Troubleshooting

If you encounter issues with your UPERFECT Screen Extender, refer to the following common solutions:

ProblemPossible Solution
No Signal / Display Not Detected
  • Ensure all cables (USB-C, HDMI, power) are securely connected.
  • Verify your laptop's USB-C port supports video output (DisplayPort Alternate Mode).
  • Try connecting the external power bricks to the extender screens.
  • Check your laptop's display settings to ensure the external monitors are detected and set to 'Extend' or 'Duplicate'.
  • Restart your laptop.
Screen Flickering / Unstable Display
  • Ensure sufficient power is supplied to the screens, especially if using a single USB-C cable. Connect the external power bricks if flickering persists.
  • Try different cables to rule out faulty connections.
  • Update your laptop's graphics drivers.
Automatic Rotation Not Working Consistently
  • Ensure the screens are firmly attached and rotated smoothly.
  • Check for any physical obstructions that might interfere with the gravity sensor.
  • Sometimes, a brief disconnection and reconnection of the video cable can reset the sensor.
Laptop Not Charging via Extender
  • Ensure the external power bricks are connected to the extender's PD ports.
  • Verify your laptop supports charging via USB-C Power Delivery.
  • Check the wattage of the external power adapter; it should be sufficient for both the screens and your laptop.
