Hia

I’m looking at working with multiple monitors.

SPAN is quite a nice new feature, however i’m wondering if there’s a way to exclude my working machines display from the output?

I have 2 or 3 external monitors coming off my laptop, but if i use SPAN, it covers my laptops display as well, not ideal as this is the working machine.

One is able to define a specific monitor with the second parameter, ie 2, it seems what i need is to be able to do, say:

fullScreen(P3D, 2, 3);

Any ideas anyone?

alternatively, is there a way to get rid of the window bar?

how does that look?

```auto
void setup() {
  fullScreen();
  surface.setSize(200, 200); //Change size here
}

void draw() {
  background(0);
  ellipse(mouseX, mouseY, 20, 20);
}

```

> No, I agree with you, and your first answer - overriding initSurface() - is the way I do this. Depending on the renderer and the OS, fullScreen() can set flags on the window that you don’t want and can cause problems. The slightly longer-winded way you posted first is a safer bet. I only use the OpenGL renderers in PraxisLIVE. Interesting these return the window and not the canvas from getNative() so I override initSurface like (where wHints is my own config object) - protected PSurface ini…

Just don’t ignore what I said in the thread @kll quoted if you want this to work reliably across systems, platforms, etc. There is more to `fullScreen()` than making things undecorated.
