Hello,

You need to to find and read the LCD datasheet and refer to the application note AN4861 "Introduction to LCD-TFT display controller (LTDC) on STM32 MCUs" then adapt the LTDC parameters to the LCD specification or try to find if there was someone implemented it or provided its driver.

Figure 4. Display module without controller nor GRAM and with external framebuffer sdram
