An external monitor is a separate display screen that connects to a computer or laptop, allowing users to expand their visual workspace. These monitors can enhance productivity by providing more screen real estate for multitasking, making it easier to view multiple applications simultaneously. They come in various sizes and resolutions, catering to different needs, from basic tasks to high-definition gaming. External monitors typically connect via ports such as HDMI, DisplayPort, or USB-C. They can be used for various purposes, including graphic design, video editing, and general office work. Many models also offer features like adjustable stands and built-in speakers for added convenience.
