Hi @Angelo_B,
Please ensure that you have connected the display in the correct position as shown in this tutorial, specifically, to use the GIGA Display Shield, mount it on the bottom side of the GIGA R1 WiFi board. The GIGA R1 WiFi board will be flipped upside down when the display is used.
If you still encounter issues, don't hesitate to contact support through this form, and we'll do our best to assist you.
Best regards,
