Your photo shows a write-only mega2560 Shield with an 8-bit interface. (4 resistor packs RP1-RP4)It is the wrong shape for 400x320. It is probably 480x320.As far as I know, the only library that will work is MCUFRIEND_kbv that you can install from Library Manager.However, it is rather complex to configure it to work with your SPECIAL board.Edit utility/mcufriend_shield.h to define USE_SPECIALEdit utility/mcufriend_special.h to define USE_MEGA_8BIT_SHIELDEdit every sketch to force tft.begin(0x9488)Plug the shield into the Mega making sure that all the male pins mate with female sockets.It is possible that your Shield has a different controller. If 0x9488 is not 100% perfect, try 0x9481, 0x9486, 0x1581, ...Please let me know how you get on. The library is intended for Uno Shields. It is fiddly to enable SPECIALs for unusual hardware.David.
