The term "dual screen" refers to a device or setup that has two separate screens, typically used for enhanced productivity and multitasking. This can include devices such as laptops with built-in secondary displays, tablets with detachable keyboards featuring dual screens, or even desktop computers with multiple monitors connected. The idea behind the "dual screen" concept is to provide more space and flexibility for users to work on different tasks simultaneously, allowing them to view and manipulate data from various applications at once. This can be particularly useful in fields such as graphic design, video editing or programming where visual elements are crucial, but it also benefits anyone who needs to have multiple windows open and accessible at the same time.
