How to cast and mirror to Chromecast
The smart TV market is convoluted with all kinds of devices, operating systems, and user interfaces. It continues to be a mess. This is what makes Chromecast dongles an enticing offering. They offer smart TV-like functionality without all the fuss and complications. Cast from your smartphone to your TV – that is the Google Cast promise. And it does this at a very reasonable price!
There are multiple ways to do this, though. Traditionally, this was only possible when connected to the same Wi-Fi network, but now it’s possible to cast without being in the same network.
You can cast content using a supported app like Netflix, YouTube, Hulu, etc. It’s also possible to mirror your Android phone’s screen to it.
You can look at our How to set up Chromecast tutorial if you need some help getting set up first.

Casting videos, images, or music is a straightforward process if your smartphone/tablet and the dongle are connected to the same Wi-Fi network. Here’s how to do it!
How to cast to Chromecast with a smartphone:
- Connect your smartphone (Android or iOS) to the same Wi-Fi network as the dongle.
- Open a supported app and launch the content you want to cast.
- A Google Cast icon will appear, usually in the top-right corner.
- Tap on it and select the device you want to cast to.

- Open a supported service’s website using Chrome.

Chromecast devices used to have a Guest Mode, which allowed users to cast to your screen without being connected to the same Wi-Fi network. This feature has been phased out.
How to mirror your screen to Chromecast
Do you have an app that isn’t supported, or simply want to show others your screen? There’s a way to do that, too! This is how you do it.
How to mirror your smartphone to Chromecast:

It’s no longer possible for a guest to cast to Chromecast without connecting to the same Wi-Fi network. This feature has been phased out, but it used to be known as Guest Mode.
Guest Mode for Chromecast is no longer supported at all. That said, when it was available, it was not available on Chromecast with Google TV dongles.
With Chromecast devices, a smartphone or tablet is needed to set up the device. However, you could get away with using a computer once you set up the device. Chromecast with Google TV products are more independent, as they run Android TV, and you can control them using the included remote. You will still need the Home app for the initial set-up, though.
Chromecast devices need the Google Home app, which is compatible with devices running Android 9.0 or later, or iOS 15 or later.
