Setup
Connecting via USB-C (Single Cable Solution)
For devices supporting DisplayPort Alt Mode or Thunderbolt 3/4/5, a single USB-C cable can transmit video, audio, and power.
- Connect one end of the provided USB-C to USB-C cable to a full-featured USB-C port on your device (laptop, MacBook, Surface, etc.).
- Connect the other end of the USB-C cable to either USB-C port on the portable monitor.
- The monitor should automatically detect the signal and display your device's screen.
Important Note: Ensure your device's USB-C port supports DisplayPort Alt Mode or Thunderbolt 3/4/5 for single-cable functionality. If the screen flickers, use the original power adapter provided. Old MacBooks may require a Mini DP to HDMI adapter. Apple M1/M2/M3 chips do not support two external monitors simultaneously.

Connecting via HDMI (Two Cable Solution)
For devices with an HDMI output, you will need both an HDMI cable for video/audio and a USB-C cable for power.
- Connect one end of the provided HDMI cable to the HDMI port on your device (PC, PS5, Xbox, etc.).
- Connect the other end of the HDMI cable to the HDMI port on the portable monitor.
- Connect one end of a USB-C to USB-A cable (or USB-C to USB-C if your power source supports it) to one of the USB-C ports on the monitor.
- Connect the other end of the power cable to the provided power adapter, and plug the adapter into a power outlet.
- The monitor should automatically detect the signal.
Important Note: Always use the original power adapter to ensure stable power delivery and prevent screen flickering, especially when using HDMI.
