Please plug in the wall charger to the Type-C port of the monitor for enough power supply.
Please contact us for help (support@mnntech.com) I use the USB Type C to USB 3.0 A Male cable to connect the monitor to my device, but it displays “no signal” The USB Type C to USB 3.0 A Male cable can only be used for power supply. This cable does not support video transmission.

My Android Phone is equipped with a Type-C port. But it does not work with this monitor.

Phones may not be able to provide enough power supply for the monitor, please plug in the wall charger to the Type-C port, then connect the phone to another Type-C port by USB-C cable.

How to save the setting of brightness?
Since our portable monitor doesn’t contain a built-in battery, it does not have a memory function, so the brightness setting of the display cannot be saved, which means you need to reset the brightness every time you turn on the display. The action of setting the brightness is easy, just simply slide the brightness adjustment wheel will be OK.

Why the brightness and contrast cannot be adjusted?
The brightness and contrast cannot be adjusted if HDR is turned on, or ECO is set to “MOVIE, GAME, TEXT… mode, or DCR is turned on. Please refer to Page 12 to reset these settings.
