Why won't my monitor turn on?
1. Please check whether the Type-C port of your device is a full-featured Type-C port that can support power and signal transmission.
2. This may be caused by the insufficient power supply. It is recommended to use an external power supply.
What should I do if it says “No signal”?
1. When connecting using a USB-C cable, please make sure your device supports USB 3.1 or Thunderbolt 3. If it is not supported, please add a Mini HDMI to HDMI cable for signal transmission.
2. Be sure to use original cables.
Could you explain why I'm unable to enable the 120Hz refresh rate on my portable monitor?
