5. Setup
5.1 Connecting to Devices
The UPERFECT portable monitor offers versatile connectivity options:
- USB-C Connection (Single Cable): For devices supporting DisplayPort Alternate Mode (DP Alt Mode) over USB-C, such as modern laptops (Thunderbolt 3/4, USB 3.1/3.2 compatible models), iPhone 15 and later, and Android phones (2020 onwards with USB 3.1/3.2 support). A single USB-C cable can transmit both video signal and power. Note: If your device's USB-C port does not support Thunderbolt 3/4 or sufficient power delivery, external power via the included power adapter may be required.
- Mini HDMI Connection: For devices like game consoles (PS5, Nintendo Switch, Xbox), cameras, and PCs that do not support DP Alt Mode over USB-C. When using Mini HDMI, the monitor requires separate power via one of the USB-C ports using the provided power adapter or a compatible power source.
5.2 Powering the Monitor
Connect the provided 30W power adapter to one of the monitor's USB-C ports (labeled 'Power' or 'PD') and then to a power outlet. If your device supports sufficient power delivery via USB-C (e.g., Thunderbolt 3/4), a single USB-C cable may be enough to power the monitor and transmit video. Otherwise, always use the external power adapter.

The included magnetic cover serves both as protection during transport and as a versatile stand. Fold the cover to prop up the monitor at various viewing angles for comfortable use.
