Hello, I am very new to STM32 boards. I just purchased an STM32F469I-Disco and have already installed STM32CubeIDE and can connect to the board via STM ST-LINK Utility v4.6.0 and see the blinking LEDs. However, when I power the board, the screen is black, and I cannot see the pre-loaded demonstration software programs.
Thanks,
Shawn

You more than likely have the newest dev board which uses a different LCD display. You might find revision B-07 on the back side. I suspect the demo FW is old and won't work as it works for the older LCD display instead. However, ST has updated TouchGFX to create a new project for this new dev board.

Thank you for your response, Karl.
I could not find any information in the ST docs about what to do for the black screen. I bought the board directly from ST, opened it immediately, and assumed all the drivers were up to date. Could you please be more specific about what steps to take?

@Shawn​
You probably won't find any documents about the screen. When you start a new project in TouchGFX you'll see 2 options for the STM32F469I-DISCO, one that mentions the newer LCD display.
