Display MHS 4 inch

Hi friends.
A favor, I am working with the display: MHS-4.0inch Display-B
(MHS-4.0inch Display-B - LCD wiki).
I am using such display with the microcontroller stm32h750, with system clock of 480Mhz, I made my own library, it works very well with spi frequency of 50 Mbits/s or lower, but when I try the spi frequency of 100 Mbits/s the display only show the white screen, such display can work up 125Mhz spi. Someone know why it happen?.

Maybe the problem is the distance of display to the microcontroller, it is about 15 cm. I am not sure.

I thank you for your help in advance.
