Black monitor for a short time when changing?

I have had a new monitor for a short time and whenever I play Fortnite, for example, and then on the other monitor and confirm something there with the mouse, both screens go black for a short time. What can I do about it? Why is that?

You will probably have both monitors connected to the graphics card.
Unfortunately, nothing can be changed because the graphics card has to be changed for the first time.
