If the blue screen is showing TA instead of DGUS, it will not work if the project placed on the SD card was created with the DGUS ii software.

For TA mode it is necessary to create the project using the TA software.

To convert the display to DGUS mode, see this other post:

There are many videos about programming these Dwin displays using the DGUS software, including on Dwin's YouTube channel, I don't know why Dwin is sending the display in TA mode  .
