Did it work previously? As delivered?

Work directly with the vendor from whom you purchased it.​

Build one of the example in the CubeF7 trees for the board that uses the screen.

One of at least half a dozen, to check screen

STM32Cube_FW_F7_V1.16.0\Projects\STM32746G-Discovery\Applications\Display\LTDC_PicturesFromSDCard

If the screen worked and you broke it, that's between you and the vendor.

What board revision? Is board blue or green?

Hi @friendlynatureperson​ ,

Please refer to the readme file that you find in the same folder as Binaries under Cube package. It provides the steps to follow in order to program the demonstration.

You can use either ST-Link Utility or STM32CubeProgrammer.
