Sending to outputs

[Pont3x]

I want to stream an image from my pi to itself (via localhost). I also want to see in the ssh terminal the same output my pi should be showing on the rpi-rgb-matrix (because in my configuration you cant see the matrix from the point of the controller).
(How) Would it be possible to output via matrix and terminal?

In case this doesn't work, how could I send from a client to the client itself functioning as server and the pi as an seperat server? (so you would have two servers with one output instead two outputs at one server)

Sincerely
Christian
