@kaslan2023, thank you for the feedback! You're welcome.
You could post the constructors you used for the data bus and display.
Are you sure about the controller ILI9341 used in the display?
If you have an Arduino UNO R3, you could check with library MCUFriend_kbv.
I am busy with some new e-paper displays. I will update my fork afterwards, and then re-test.
But you can see the way I use to configure examples with Arduino_GFX here:
https://github.com/ZinggJM/Arduino_GFX/tree/known_tests/examples/PDQgraphicstest
e.g. in known_good.h
I like this library, as it supports most TFT displays I have, and some more I'd like to discover.
And the whole selection of display and configuration can be done in the example or application.
Good Luck!
