STM32H747-Disco LCD Demo

Hello all,

maybe someone know what’s going wrong:
With mbed studio I build the LCD demo for a STM32H747I-Disco board. I put the program on the board, and it started (so far).
But the dispayed content on the screen look’s not good. There are vertial lines over the complete display…

What I tried:
With the Cube programmer I unchecked BCM4 (CM4 boot enable)
