The screen when playing games is reduced to the maximum size

Another problem you may encounter when using the second monitor is that the game you are playing on one screen is reduced to its maximum size for no apparent reason. You may accidentally click on the second screen because there is nothing separating the screens.

If this happens to you, try one of the following troubleshooting tips:

1. Check out the options displayed in the game itself. If you're playing in 'Windowed' mode , try switching to 'Full Screen' mode instead.
2. Try switching to 'Borderless Window' mode. This mode will not prevent you from moving the mouse to the other screen, but it will prevent the screen from being reduced to the maximum size when you are playing the game.
3. Try the Dual Monitor Tool (reference link: http://dualmonitortool.sourceforge.net/ ). The Cursor tool allows you to lock the mouse pointer on one of the screens. Remember to unlock when you finish the game!
4. Turn off the second screen or press Win + P to change the screen only to the desktop.

Use these tips to make using a second monitor an experience that makes you more satisfied and reduces problems that prevent you from completing a task.

Hope you are succesful.
