2. Please confirm whether the resolution of the LCD screen is the same as the resolution of the LCD controller board (Please refer to the controller board purchase link which has marked compatible resolution, use the screen type to search on the network to confirm its support resolution), if not, please contact with seller, some boards after updating the firmware will fix this problem.

2. The input resolution is inconsistent with the LCD menu display resolution, it is due to the LCD screen controller board writes the common resolution, corresponding to the special resolution, and the control board menu displays the common resolution. If you want to display the same resolution, it needs to modify the EDID data of the LCD screen. If you encounter this situation and need to improve it, please contact us.

Q13: When to use Type-C connect to the Phone, it can’t turn on or the brightness is very low.
–A13: 1. The input current of the mobile phone is not enough, and it is not possible to input enough current to allow the control board to run while transmitting signals.
2. When the phone is turned on, the default brightness is turned on. The input current of the mobile phone is not enough. You need to connect an additional power adapter to the control board.
