Hi,
There are no ST discovery board with a 7 inch display to my knowledge, but I know that the STM32H7B3 evaluation board has a 7" 800*480 TFT RGB LCD display.
To understand how to setup the display with the ST toolchain have a look at the Board Bring Up articles in the documentation . There are also a couple of videos made by ST and other users which can be of use. Depending on the display interface you will use you can have a look at the relevant TouchGFX Board Setups and Board Specific Demos available in TouchGFX Designer and use them as source of inspiration for your configuration.
It is a bit difficult to say if an STM32F7508 discovery board will be able to use a 7 inch display, I can just point that the framebuffer necessary for a 1080*600 resolution will be HUGE so watch out for the memory consumption. Otherwise stick to a 800*480 with 16bpp ( framebuffer size = Width * Height * bpp/8 = 768 000, so still huge).
Now, where you can get a 7-inch display ? Well that kind of depends where you are located and the amount of display you want. I'll let other users comment on this.
