We are about to switch to a new forum software. Until then we have removed the registration on this forum.
Had this message: Could not parse -1 for --display while running sketches via VNC on Pi. I understand, that the actual Display is :1 - which is virtual and the HDMI is actual Display :0. It still does work, but could that be configured, so the compiler is aware of the display? Or could be redirected to a display? Eg. Controlling IDE via IDE but displaying the applet to another display real one (HDMI)?
