Connect multiple screens on raspberry pi 4 model B

Question

Hi,

I allow myself to contact you in order to know if it's possible to connect 6 screens to one Raspberry PI 4 model B.

Moreover, I want the 6 screens to show completely different content, I want them to be completely independent from each other.

I tried to find out the answer of my question on different platforms but I'm still not finding a solution.

Thank you in advance,

Kind regards,

Camille

It depends what info you want to display.

The Pi4 is only designed to run 2 HDMI displays and 1 MIPI DSI screen, so you cannot generate 6 different video streams simultaneously.

If you only want 6 static screens that only update periodically, you would still need smart displays that had built-in computers that could receive images via ethernet.

You can run 6 screens with a PC or a Mac, but running 2 or 3 Pi4s to get 6 screens is cheaper than running a PC or Mac.
