Work screen + presentation screen

I am looking for something probably stupid but I can not find how to do this. I have a computer with a projector connected. I wish that the renderer displays on my videoprojector full screen while continuing my programming on my computer screen. I’m sure this is possible but how?
Thank you for your help.

guess, you should drag your Renderer(EX9) window to the projector screen and press alt+enter

Thanks ! It works perfectly.

as vvvv always do
