A "Dual-Screen" setup refers to the use of two separate display screens connected to a single computer or device. This configuration allows users to extend their workspace, making it easier to multitask by viewing multiple applications or documents simultaneously. It is commonly used in offices, gaming, and creative industries to enhance productivity and improve workflow. Many modern laptops and smartphones, such as the Microsoft Surface Duo and LG V60 ThinQ, feature dual-screen capabilities. These devices can run different apps on each screen or mirror the same content, providing flexibility for various tasks. Dual-screen technology is becoming increasingly popular for both personal and professional use.
