To install the firmware (specifically for a 1920x1080 resolution), follow this guide for flashing the LCD panel driver board via USB. 1. Preparation

Turn on the power. An LED light sequence on the board or its connected keypad will indicate that flashing has begun.

Note: If you are using a Mac, ensure you delete any hidden resource files (starting with ._ ) after copying, as they can interfere with the flashing process.

A successful flash should display an image correctly on your 1920x1080 panel.

Insert the USB drive into the board's USB port.

Do turn off the power during this process to avoid bricking the board. 3. Verification
