Connect one end of the USB-C cable to the monitor's USB-C port and the other end to your laptop's USB-C port. The monitor should automatically detect the signal.
4.2 Connecting to a Laptop/PC (HDMI)
For devices using HDMI, connect the Mini-HDMI to HDMI cable from the monitor's Mini-HDMI port to your device's HDMI port. When using HDMI, external power is required. Connect the USB-C to USB-A cable from one of the monitor's USB-C ports to the provided wall charger or another suitable power source.
4.3 Connecting to Gaming Consoles (PS5, Xbox, Switch)
Connect your gaming console to the monitor using the Mini-HDMI to HDMI cable. Ensure the monitor is powered via the USB-C to USB-A cable and wall charger. For Nintendo Switch, use the official Switch dock to output the video signal via HDMI to the monitor.
4.4 Using the Smart Cover as a Stand
The included smart cover can be folded to create a stable stand for the monitor, supporting both landscape and portrait orientations. Adjust the folds to achieve your desired viewing angle.
