Hi all, where can I find a guide for dummyes about how to connect and maybe run the nucleo-f767 board whit LCD display with RGB 24bit interface ?

Pretty sure there isn't one.

Step One would be to identify the pins usable for such an interface, the choices are pretty limited/finite.

The board also lacks any external memory to hold a usable frame buffer.

Consider a display with its own buffer, and interface it via the FSMC/FMC

Look at the EVAL board reference designs, and those for the DISCO

The F769I-DISCO has a DSI interface, and replaceable screen/connector

I'm agree with you that it is not the sympler way.

But the STM32F767xxx series seem to have all you needs to drive an RGB interface, using its internal ram and flash.
