Drive dual displays from a single STM32F400 series MCU

We are designing for an application having front and back-facing 7' displays.  I am keen to hear suggestions for running both displays from the same processor using using LTDC or display peripheral?

Both displays will have different images.

Resolution will be somewhere around 800 x 480 in each display, so relatively lo-res.

That's a much better solution.

no CPU overhead to refresh the screen, its a huge difference in performance.

as many displays as you want. with a fast update.

otherwise, SPI is the best but the update speed is like 1000x slower than the 'MCU interface.'
