Hi there,

I am currently writing a program to control a LED-Wall. The LED-Wall is connected via DVI and acts like a normal connected second Display.

I use the normal Monitor (Screen from Laptop) as Control Panel and Preview

I created a second PApplet which gets displayed on the LED-Wall with JFrame.

I run into problems when I use the same PGraphics to display the Preview on the Laptop-Screen and the PGraphics I "send " to the LED-Wall. It seems that only one PApplet can use the PGraphic.

In this case my Laptop gets the PGraphics:

1. void draw(){
2.       image(frame,0,0);
3.       secondApplet.image(frame,0,0);
4. }

In this case the LED-Wall gets the PGraphics:

1. void draw(){
2.       secondApplet.image(frame,0,0);
3.       image(frame,0,0);
4. }

Is that some kind of bug or is that something in the Graphics Card that outreaches my knowledge about these?

Thank you
