This setup enables you to view reference materials, documents, or communication channels on one screen while focusing on your primary tasks on the other.

Enhanced multitasking capabilities

Having a second display allows you to divide your work across two screens, enhancing your multitasking capabilities. For example, you can work on a spreadsheet on your desktop while monitoring emails or chat applications on your laptop’s screen. This setup minimizes distractions and streamlines your workflow, resulting in improved efficiency and time management.

Convenient portability

Laptops are designed for mobility, allowing you to work from anywhere. By using your laptop as a second display, you can carry your workspace with you and enjoy the convenience of having a dual-screen setup wherever you go.
