Advise on buying and controlling multiple TFTs

Hi,

I'm currently doing a feasability check for one of the projects I have in mind. Maybe you guys can help me out with some advise (thanks in advance!).
I have an Arduino Uno and I would like to control 4 TFTs at the same time. My questions:

  • Can you guys advise me on cheap TFTs? Which ones have you successfully used in your projects?
  • Is it possible to control 4 with only one Arduino? Or would you advise to use one Arduino per screen?
  • I want to control 4 at the same time, meaning that there will be 4 buttons that can be pushed, upon pushing an image will be displayed.

Thanks in advance for your reactions!

Greetings,
Joost
