Display orientation refers to the arrangement of the screen content in relation to the physical orientation of the display device. It is an important aspect of user experience and can greatly affect productivity and usability. In Windows, display orientation can be adjusted to suit individual preferences or specific requirements.

By default, the display orientation in Windows is set to landscape mode, where the width of the screen is greater than its height. However, there are situations where changing the display orientation becomes necessary. For example, if you are using a tablet or a convertible device, you may want to switch to portrait mode to optimize the screen layout for reading or writing. Additionally, some applications or games may require a specific display orientation for proper functionality.

To adjust the display orientation in Windows, you can follow these steps:

1. Right-click on the desktop and select "Display settings" from the context menu.
2. In the Display settings window, scroll down to the "Orientation" section.
3. Click on the drop-down menu under "Orientation" and select the desired orientation option (e.g., Landscape, Portrait, Landscape (flipped), or Portrait (flipped)).
4. Once you select the desired orientation, the screen will automatically rotate to the new orientation.

Alternatively, you can also use keyboard shortcuts to quickly change the display orientation in Windows. Pressing the "Ctrl + Alt + Arrow" keys will rotate the screen to the corresponding direction (e.g., Up arrow for Portrait mode, Right arrow for Landscape mode, etc.).

It is worth noting that not all graphics drivers or display devices support all display orientations. In such cases, the available options may be limited. Additionally, changing the display orientation may affect the orientation of the mouse cursor, so you may need to adjust your mouse movements accordingly.
