How does a chromecast work on a tv
A Google Chromecast plugs into your TV’s HDMI port and uses your home Wi-Fi to stream audio and video from your phone, tablet, or computer directly to your screen.
How Chromecast Works
• The Connection: You plug the device into an HDMI port on your TV and connect it to a power source. It connects to your home Wi-Fi network.
• The Cast Command: When you open a supported app (like YouTube or Netflix) on your phone or computer, you tap the Cast icon.
• Direct Streaming: Your phone does not actually send the video file through the air to the TV. Instead, your phone sends a web link (URL) to the Chromecast.
• Screen Mirroring: You can also use Chromecast to mirror your entire phone, tablet, or laptop screen onto the TV display.
