How can you extend your desktop across multiple monitors?

To extend your desktop across multiple monitors, the "Extend these displays" setting is used. This option allows you to spread your workspace across two or more screens, effectively increasing your available display area. When you select this setting, each monitor operates as an independent display, providing more real estate for applications and windows and enhancing multitasking capabilities.

This feature is particularly useful for users who want to increase productivity or enhance their viewing experience for tasks such as gaming, graphic design, or software development. By extending the display, you can drag windows and applications from one screen to the other seamlessly, creating a cohesive workspace.

In contrast, the other options serve different purposes. For instance, "Duplicate these displays" mirrors the same content on both screens, limiting screen real estate to what can fit on a single monitor. The "Projector only" option disables the primary display and shows output only on the secondary monitor, while "Display only on 1" implies using only the first monitor, effectively ignoring any additional displays. These options may have their specific use cases but do not provide the functionality needed to extend the desktop across multiple monitors.
