Follow these steps to set up your UPERFECT portable monitor.
4.1. Connecting to a Power Source
The monitor can be powered via a USB-C connection from a compatible device or an external power adapter.
- Via USB-C (Single Cable Solution): If your device (e.g., laptop, smartphone) has a full-function USB-C port (supporting DisplayPort Alternate Mode and Power Delivery), connect one end of the provided USB-C to USB-C cable to your device and the other end to one of the monitor's full-function USB-C ports. This single cable can provide both video signal and power. Note: If your device's USB-C port does not support sufficient power delivery, or if it's not Thunderbolt 3/4 compatible, you may need to connect an external power source.
- Via External Power Adapter: Connect the provided USB Type-A power adapter to a power outlet and then to one of the monitor's USB-C ports using a USB-C cable. This ensures stable power delivery, especially when using HDMI for video input or connecting power-intensive devices.
4.2. Connecting to Devices
The monitor supports various devices through USB-C and HDMI connections.
- For Laptops/PCs (USB-C): Connect a USB-C to USB-C cable from your laptop's full-function USB-C port to the monitor. Ensure your laptop's USB-C port supports DisplayPort Alternate Mode.
- For Laptops/PCs (HDMI): Connect the provided HDMI to Mini HDMI cable from your laptop's HDMI port to the monitor's Mini HDMI port. You will also need to connect the monitor to a power source via USB-C.
- For Smartphones: Connect a USB-C to USB-C cable from your smartphone's full-function USB-C port to the monitor. Ensure your smartphone supports video output via USB-C (DisplayPort Alternate Mode).
- For Gaming Consoles (Nintendo Switch, PS4/PS5, Xbox): Connect the provided HDMI to Mini HDMI cable from your console's HDMI output to the monitor's Mini HDMI port. The monitor must also be powered via its USB-C port using the external power adapter.
