To move a window to another monitor on Windows 10, you can follow these steps:

1. Make sure both monitors are connected to your computer and turned on.
2. Click on the title bar of the window you want to move to another monitor. The title bar is located at the top of the window and displays the window’s name.
3. While holding the left mouse button, drag the window to the edge of the screen in the direction of the target monitor. As you drag, the window will appear to be “attached” to the mouse cursor.
4. Continue dragging the window across the edge of the screen until it moves onto the desired monitor.
5. Release the mouse button to drop the window onto the new monitor. The window will now be displayed on the selected monitor.

If you have multiple monitors arranged in different configurations (e.g., extended display or mirrored display), you may need to adjust the position of the window further to fit your desired layout. You can repeat these steps to move windows between monitors as needed.

Alternatively, you can also use the keyboard shortcut “Windows key + Shift + Left/Right arrow” to move a window to the left or right monitor, respectively. This keyboard shortcut is especially useful when you have multiple monitors set up side by side.

Remember that the ability to move windows between monitors is dependent on your specific hardware configuration and display settings.
