Hello and Welcome,
DO you have a link to the specific display?
Is it a touch screen model?
How are you connecting the Hardware? Always start with that.
then post what software you have tried and or what errors you are getting?
They are Great Displays with the touch screen , even better.
Even on the Round Display the touch portion makes the code more specific.

FYI, Not all TFT_eSPI libs are the same.
(from the wiki) If you have previously installed the TFT_eSPI library, please remove the original library and install the new one.(download from that link only?)
