It is relatively trickier to for users to handle when a traditional display screen comes with a control box to operate together with a user manual.But with a smart control box, you can control the display screen through a mobile APP as well as display the pictures which you upload.
Either WiFi or bluetooth connection can be used to manage control between the smart box and mobile APP in Brightness adjustment, screen control,color-temperature control, screen on-and -off,screen power supply control and uploading and display of local pictures from the phone.
Either automatic adjustment or manual adjustment is available in brightness adjustment
Chroma adjustment or brightness adjustment at first is alright, separately or together.
Power on or off command
Manage the display mode and screen rotation control
Receive the screen size and video size from the transmission box via the protocol command
Just need to send a quick connection screen command to the transmission box
