Hi.
Do you know more details about your display? But it uses a different driver?

Hi Sandra, Although your answer was not enough for me, because I was working with a tested ESP32, so I think it was a driver update, but thank you for the answer. But the cause was incorrect wiring between the module and ESP32. Faulty connectors that slipped out of the contacts. After replacing the cables, everything works correctly with the new ESP32 30 pins.
Have a nice day. Evžen
