Set values of LTDC Timing for stm32f429ZI

Hello

I have a TFT_LCD 5.7 inch. I want start up it with STM32F429Discovery but I have a problem according to the LCD datasheet

I have to set Vsync (Front-Porch) = 4.5 TH (Hsync Period).

But I can't give float numbers to the LTDC registers.

LCD datasheet attached.

Please help me if anyone can.

It is a typical value, must not be exact, so I'd just try it with 5. General rule: if you can't exactly match a required delay, round it up.
