↑This is a follow-up to my previous post.

 

However, the displayed image is extremely blurred, and it is difficult to recognize what is shown on the screen.

What should I check or adjust to display the image clearly?

Hello @chachamaru;

 

Are you able to display image or color from a frame buffer?

Please look at Introduction to LCD-TFT display controller (LTDC) on STM32 MCUs - Application note application note section 7 LTDC application examples  and get inspired to check the LTDC settings.

 

Thank you.
