How to Turn On Your Chromecast TV Without Your TV Remote
Google currently makes two Chromecast dongles that turn your regular TV into a smart one: the Chromecast ($35) and the Chromecast Ultra ($69), the latter of which supports 4K HDR displays. You can also buy a Chromecast-enabled TV, which allows you to cast content to your TV without having to buy a separate device that takes up an HDMI slot.
If you watch TV with Chromecast, either with a dongle or with it baked into your TV, you’ll know that you can control the TV with your phone or tablet via the Google Home app. But a common frustration, albeit a small one, is that casting something requires your TV to already be turned on and switched to the correct HDMI input, which can be cumbersome with older models.
If you have a Google Home smart speaker, when you ask it to cast something to your Chromecast TV, it’ll turn the TV on and switch to the correct input in one fell swoop. But, with this hack, you can do it all yourself in one easy motion as well.
With your TV on, open a supported app on your smartphone or tablet, like Netflix or YouTube, and click the cast button. If you’re using a Chrome browser, you can click the three vertical dots in the top right of your browser, and then click “Cast.” The content should appear on your TV.
