1. Plug your Chromecast into your TV. This step is self-explanatory, but good luck getting your Chromecast to work without performing it. Plug the Chromecast into an HDMI port and its power cable into a USB port. If your TV lacks a USB port, you can use a power adapter (not included) and plug it into the wall instead.
Plugging it in. Plug the Chromecast into your TV, connect the power cord, turn on the TV, and switch to the proper HDMI input setting. Next, download the Chromecast app on your iPhone or iPad, and while it is installing go to Settings, turn on Wi-Fi, and connect to the Chromecast option. Screenshot by Dan Graziano/CNET.
