Hi, the crux of the matter, is it possible to implement such an application:

Suppose we have two monitors on one PC, and no matter how they are connected to the PC, whether it is one video card with two VGA, or whether it is two video cards, that is, one for each monitor, any connection option is possible, one monitor Us, our worker, we work with him in the normal mode, but with the second one a java application is working, that is, a banal program displays a message on the second monitor, suppose on a blue background "hello world", really?

if there really are some ideas, I assume that it is necessary to drip in the direction of winapi, although I may be wrong

    I do not see any problems. In Swing, get the handle on the 2nd, 3rd and generally any display is not a problem:

    GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice[] gs = ge.getScreenDevices(); //возвращает массив устройств int numDislays=gs.length; //количество мониторов
