using a secondary display

Is it possible to force a Processing program to run on a second (non-primary) display, particularly in presentation mode? I have a large screen display connected to my laptop and I would like to launch my Processing program in full screen mode on that display.

On Win7: on desktop -> right click -> resolution -> then click on the BIG screen -> "make this my primary monitor"

In Processing, use ALT+SHIFT+R to run full-screen application

This would work.

Thanks, yes, that works, and it is what I'm doing now. However, it switches everything to that display (e.g., my desktop icons and menu bar). I'm looking for a way to launch from my laptop display and have it open full screen on my secondary display.

Hi, you can do fullscreen on the secondary monitor like this:

public void init(){
frame.removeNotify();
frame.setUndecorated(true);
frame.addNotify();
super.init();
}
void setup() {
size(1024,768, OPENGL); // set to the size of the second display
frame.setLocation(1440,0); // set to the position of the second display
}
public void stop() {
super.stop();
}

Thanks--this information is what I needed.

I'm using Processing libraries directly from Java, so am starting Processing with PApplet.main. The problem was that I was using the "--present" flag to start in presentation mode, but that apparently thwarts attempts to locate the window on the second display. By using your init code to remove the frame decorations, I was able to stop using "--present" and the "--location" command line option started working. (frame.setLocation(...) in this context seems to have no effect.)

As a side note, perhaps because my secondary display is located to the left of my main display, I had to use a negative position ("--location=-1920,0").
