What Is Screen Mirroring and How Does It Work?
Often referred to as screen sharing, screen mirroring is the process of duplicating a different display. This functionality is commonly used in conferences, classroom presentations, and video calls.
Screen mirroring on Mac can be done in two ways. You can use a cable to connect your device to the TV screen or install an app. Each method has upsides and downsides - for example, wires have limited length and get in the way, while Wi-Fi has a delay and requires a consistent connection.
Wired and Wireless Solutions to Share Your Screen
Wired Mirroring. HDMI cables are used to connect devices to an external display. If you are using a device that has an HDMI port, then you only need to connect one end of the cable to the device and the other one to the display. Older devices may not have HDMI ports; VGA was common, and it requires an adapter to connect to HDMI. USB to HDMI also exists, but it’s much better to have a dedicated graphics port.
Wireless Mirroring. If you mirror Mac to TV wirelessly, you’ll get similar results to wired mirroring. It’s pretty easy to work with, since most devices come equipped with built-in wireless capabilities nowadays. Not having to deal with tangling cables is another plus.
