thanks for the info! That is pretty much, what took me hours to seek and find ;-)
According to this:
there should be a plurality of different possible displays. As I wrote, I am especially interesetd in a 3,5" display and will get the one you mentioned. Is there anything I have to do to get it working or will it work out of the box?
If you need support for testing different displays I could also get other displays and we could coordinate the efforts.
Just let me know if you want any help.
