Hi, first post in a decade!

I would like to send differing output to two different displays, each in fullScreen mode. I’m running Processing 4.2

For example, on a Windows computer with a monitor and a projector as displays 1 and 2, I would like to display one PGraphics on display 1 and a different PGraphics on display 2, at the same time.

Is this possible?

Thanks!

Hi @jstarbell

I need to get this working as well, did you get it working?

Cris.

No. I ended up using multiple computers with network information sharing.

Wow i hope you might have better luck. I would still like to do it with multiple displays in the same program.

Best of luck,

Hello @jstarbell and @Flustered,

I was able to use Spout to direct several _PGraphics_ to separate receiving sketches and display those on separate monitors.

These are all on one screen:

Adding _fullScreen()_ with the display number to the receiving sketches directed it to separate monitors.

Reference:

> **[fullScreen() / Reference](https://processing.org/reference/fullscreen_)**
>
> This function is new for Processing 3.0. It opens a sketch using the full size of the computer's display. This function must be the first line in setup(). The size() and fullScreen()\<…

Explore the examples that come with the Spout Library:

I used:

- MultipleSpoutSenders
- SpoutDataReceiver (receives one _PGraphics_ to display)
- SpoutDataReceiver 2 (copy of above sketch for the second _PGraphics_ to display)

It was simple enough to do once you get familiar with Spout and examine the example code provided and modify as required.

Have fun!
