Using a parallel TFT display with ESP32

Using Arduino Displays
1

Hi. I bought a cheap TFT LCD and I want to use it with my ESP32 DEVKIT V1.
Since it's a Chinese cheap display from EBay I haven't any datasheet. I't a 3.5" LCD TFT SHIELD (image below). It's an UNO shield: I tried it on a UNO with the Adafruit_TFTLCD library and it works. It can't automatically detect the driver ID (returns 0) but forcing it to be ILI9481 works.
I found this post so I tried the TFT_ESPI library, enabling the correct User Setup and using the same pins as described in the configuration, but the screen remains blank.
Has anyone managed to make one of those displays work with the ESP32?

Thank you.

You may be getting ground bounce issues due to long wires between the boards. Try adding extra 0V (GND) connections and keep all the wires as short as possible. The best option is to use an UNO style ESP32 board with the display as this is a tested combination that is less error prone.

The picture posted suggests you have not connected all the required pins up, but I am guessing these connections were removed to take the picture...
