    Hello zal,

    thank you for the photos. You have really nice screw terminals for the flat cables :)

    Again – I have checked your setup and do not see any obvious reason why it should not work.

    Do you have any idea how fast is the communication with the display?

    Please note that there are some protection serial resistors on the pin header lines which may slow down edges of the very fast signals. Do you have any chance to check it with oscilloscope?

    Even that according the datasheet the display should take max 120 mA, mabybe the 5V at the pinheader is overloaded – please, try to supply it externally – at least as part of the investigation.
