Rotation of STM32F429I-Disco LCD

So I've been through the HAL, the CubeF4, and the StdPeriph library. 
There are many functions to do many things to the LCD but I cannot for the life of me find one to rotate the LCD or initialize it in with a landscape or portrait type orientation.

I have seen some parameters such as LTDC_VerticalStart but what exactly the parameter controls is unknown and not documented.

I have discovered that by manipulating the MADCTL bits in the ili9341.c the orientation can be changed. But then then I have width and sync issues.

I just don't get why ST went through all that trouble to create an interface for the LCD and touchscreen, then left out something so simple. Or is it there and I just don't see it?

BTW I don't want to use SPI to control the LCD, so please don't suggest using a third party SPI library. I want to use the LTDC lib.

I've read the ili9341 datasheet, its not very helpful either.
