I want to assign a different screen to each dual monitor through ndisplay, what should I do?

I wanted to make a dual monitor with the same pc, the same IP address, into two monitors and assign a screen to each monitor.

If you press the red mark, the two nodes turn on, but they are concentrated only on the main monitor. How do we solve this?

follow these steps and add second window at X= 0 Y= 0 Position.
