3. Setup and Installation
3.1 Unpacking and Initial Inspection
Carefully remove the monitor from its packaging. Inspect all components for any signs of damage during transit. Ensure all accessories listed in the package contents are present.
3.2 Connecting to Your Device
The UPERFECT Dual Portable Monitor supports both Type-C and Mini HDMI connections. No drivers are required for most operating systems.
- For Windows Devices (Single Type-C Cable):
Connect one end of the provided full-function Type-C cable to the monitor's Type-C port and the other end to a full-function Type-C port on your Windows laptop or PC. The monitor should automatically detect and extend your display. Ensure your device's Type-C port supports video output and power delivery.

- For macOS Devices (Two Type-C Cables):
Connect two Type-C cables from your macOS device to the two Type-C ports on the monitor. This configuration is typically required for macOS to properly recognize and utilize both screens. Ensure your MacBook has sufficient Type-C ports or use a compatible hub.
- Using Mini HDMI:
If your device does not have a full-function Type-C port, you can use the Mini HDMI port. Connect the provided Mini HDMI cable from the monitor to your device's HDMI port. You may also need to connect a separate USB-A to Type-C cable for power if the HDMI connection does not provide sufficient power.

3.3 Power Supply
While the monitor can often draw power from a full-function Type-C connection, it is recommended to connect the included power adapter for stable operation, especially if your device's port cannot provide sufficient power or if you experience brightness issues.

5. Maintenance
5.1 Cleaning the Monitor
