Aliexpress Displays between 2€ and 5€, tested with ESP32 Wemos lite, Arduino IDE 2.3.2 and TFT_eSPI 2.5.43.
Arduino IDE Board : "WEMOS LOLIN32 Lite"
All three displays work stable with 80MHz, even with a 50cm long cable between ESP32 and display.
Similar tests but with a RP2040 (ESP32-S2, S3, C3, C6, H2) and more displays can be found in the folders RP2040 , ESP32_S2 , ESP32_S3 , ESP32_C3, ESP32_C3_Super_Mini , ESP32_C6 and ESP32_H2.
