7 or 8 Inches display on custom board based on F746

[SKokk.1]

Hello,

On a custom board (similar to F746-Disco board) i was able to setup a 5' display with 800*480 resolution on RGB565.

Now, i would like to support bigger display with same board. As i checked, there are many 7+ inches displays with RGB interface.

Is there any limitation on the maximum resolution?

As i read, with F7 i can reach up to 1024*768 resolution. This number is related with the maximum frame rate or i could go to higher resolutions by reducing the frame rate?

The resolution depends on the refresh rate of course.

Table 12 of AN4861 gives you an overview of supported resolution and you can see you can do 1920x1080 at 30Hz and 16bpp.
