I want to use my Hyperpixel 4.0 on 30/45fps because I'm having some issues with other USB-Signals in combination with the pixelclock speed. I noticed that these issues don't occur if I set the pixelclock to 19,2MHz or 25MHz instead of the default 32MHz. Furthermore, I don't really care about the framerate because I mostly of the time have still images.
Unfortunately I don't have a clue how to perfectly coordinate the pixelclock to the reduced framerate. Does anyone know how to properly reduce the pixelclock/dpi settings? I use the Compute Module 4 in case if this has any impact on setting the pixelclock.
