Hi Leigh
would it be possible to add more clock settings?
or can I do this in my program as C code?
These settings here are not enough for the display probably

I don't understand how this works but we can test these settings first

Ah, well spotted, looks like that LCD clock needs some attention then.
I'd forgotten that this device has an LCD controller, it's been quite a few years since I worked with this device.
I am still somewhat limited in the time I can put to technical investigations, hopefully someone can get there before me

Hi Leigh
I have tried but there is a small problem.

Re: STM32F469I-DISCO Board clock setup
Yes compile works,
I have tested different settings
but the display only works correct, if I increase the delay time from 8 to 16Mhz, but then I2c and UART no longer work properly.
I will test the settings again and maybe we should have a look at the reset pin of the display LCD_reset
