I would like to use an STM32F7 MCU to drive a MIPI 1920x1080 display.
I have seen that the max supported resolution for this type of MCU is 1024x768, but I am asking to know if there is an embedded mechanism that allow me "to plot the same pixel" of the frameRAM more than one time into the display. In this way I can continue to use the MCU facilities and at the same time use a panel that I am already using in another product. Please, someone can help me? Thank you in advance.

Pretty sure it doesn't have the bandwidth to sustain a screen that large via two lanes, nor the interpolation to achieve it either.
You would need to see if your display side controller supports other modes, and interpolation. ie a monitor supporting DSI to HDMI/DVI. and recognizing the sync patterns.
Used an F769I-DISC1 with an DSI/HDMI adapter to drive a 1920x1080 panel at lower resolutions.
