Most smart projectors on the market support connecting external mouse and keyboard, which greatly enriches the operating functions of projectors and makes up for the inconvenience of traditional remote control operation. Early ordinary projectors only had simple projection functions and could not connect external accessories, but all current smart projectors with Android systems are equipped with universal connection interfaces and wireless connection functions, which can perfectly match wired and wireless mouse and keyboard, bringing a more flexible and efficient operation experience.

There are two main connection methods for mouse and keyboard. The first is wired connection, which is the most stable and compatible way. Projectors are equipped with standard USB interfaces, and users can directly insert the USB data cable of wired mouse and keyboard into the projector’s USB port. The device will automatically identify and install the driver within a few seconds, and no manual setting is required. After the connection is successful, a mouse cursor will appear on the projection screen, and users can use the mouse to click icons, browse web pages, and select videos, and use the keyboard to input text and search content.

The second is wireless connection, which is more convenient and tidy. Users can use a 2.4G wireless mouse and keyboard set, insert the supporting wireless receiver into the projector’s USB interface, and the connection can be completed automatically. In addition, many Bluetooth-enabled projectors can directly pair with Bluetooth mouse and keyboard without occupying USB interfaces. After connecting the mouse and keyboard, the projector can realize computer-like operations, such as office document viewing, online searching, and game operation, which greatly expands the usage scenarios of home projectors and improves the practicality of the device.
