What is screen mirroring and how does it work?
Screen mirroring is a technology that allows users to project the content of their device’s screen to a larger display, such as a TV or projector. This can be done wirelessly using protocols like Miracast, Chromecast, or AirPlay, or through wired connections like HDMI cables. Screen mirroring is commonly used for presentations, watching videos, or sharing content with others.
The process of screen mirroring typically involves pairing the device with the display device, either through a wireless network or a direct connection. Once paired, the device’s screen is replicated on the display device, allowing others to see what’s on the screen. Some devices may require additional software or hardware to enable screen mirroring, while others may have it built-in.
Is WiFi necessary for screen mirroring?
WiFi is not always necessary for screen mirroring. While many screen mirroring technologies rely on WiFi to transmit the signal, there are alternative methods that do not require a WiFi connection.
