Some Smartphone when connected to the 15.6 inches WIMAXIT "Touchscreen" portable monitor will automatically produce a display or output , that means , it mirrors the Smartphone .

Take for example , if  we use use a SAMSUNG Galaxy Note 8   to connect to the  15.6 inches WIMAXIT  "Touchscreen"  portable monitor , to mirror the SAMSUNG Galaxy Note 8 display ,  we need only  1  USB Type-C cable   That means one end of the USB Type-C  male Cable go to the SAMSUNG Galaxy Note 8 female port and the other end of the USB Type-C male Cable go to the WIMAXIT  15.6 inches USB Type-C
female port .
The cable is meant to provide power charging and data transfer (audio/video) .
