Can You Use Two Chromecasts in One House? (Here's How)

As an owner of two Chromecasts in my home, I was frustrated to find out that there was no easy way to get them both working together. After hours of testing and research, I’m here to share how I managed to get both of my Chromecasts up and running at the same time, as well as other potential solutions I discovered. In this blog post, I’ll discuss how you can use two Chromecasts in one house, and the best way to get them both working together.

Yes, it’s entirely possible to set up multiple Chromecast devices in a single house as long as you give them unique names, connect them to different TVs, and have the bandwidth to support simultaneous casting.

How Can You Use Two Chromecasts in One House?

To get started, you’ll need two HDMI cables, two Chromecasts, two TVs, a sturdy internet connection, and a casting device (or two).

Connect Each Chromecast to a TV

First things first, use the basic steps to connect each Chromecast to the designated TV.

Here’s how:

Plug the TV and Chromecast adapter into power supplies and turn them on.
Get the HDMI cable hooked between the Cast and the TV.
Connect the Chromecast and casting device to the same home WIFI network.

Get the Google Home app on your casting device (mobile, tablet, etc.)
If the setup prompt doesn’t pop up, click on Add, then Set up New Device.
Choose a clear name for the Chromecast based on the room it is in instead of numbering.

Once you’re done with one Chromecast-TV set, repeat the steps with the other pair.

Choose a Device to Cast From

By now, you should have a network of two Chromecasts, each connected to a TV. What you need to test next is the actual casting.

The most common method here is to use different devices to cast from, but it’s also possible to use a single laptop to throw content to the two Chromecasts.

Let’s see how you can try each method:

Casting From Two Devices

The casting process is easy if you use two mobile or tablets to set up your Chromecasts.

You just open any app or platform that’s Chromecast-enabled and click on the small cast icon on the side. It should look like a screen with connectivity curves on the bottom left corner.

Alternatively, you can do it from the Chromecast app:

Double-check that the network is the same for the Chromecast and the device.

Open the app, select Cast Screen, and then confirm.
Check that the TV is mirroring the same content.
Repeat the process from the other device to cast to the second TV-Chromecast setup.

Casting From One Device

If you want to cast to the two Chromecasts from the same device, we recommend trying it out from a laptop to make things easier.

Here’s how:

Launch the Google Chrome browser on your device and open up two windows.

Change the user on one window (the small circle next to the three dots on the top right corner).
Once each window runs a different user, you can click on the three dots and select Cast.
Choose one Chromecast for each window. Again, naming by room can help cut down the confusion here.

Try Grouping Your Chromecasts

If blasting music in different rooms simultaneously sounds intriguing, you can try the multi-room feature in Chromecast.

Here’s how:

From the Google Home app on your casting device, click on Add, then Create Speaker Group.
Bundle the two (or more) Chromecasts together and select a name.
Confirm the settings and play a song to test the setup.

To control volume, open the Media tab and adjust each Chromecast’s desired volume level.

Is It Possible to Connect One Chromecast to Two TVs?

While it’s definitely more convenient to use a separate device for each TV, there’s still a way to connect one Chromecast to two TV sets in the same house.

The trick is getting an HDMI splitter to take that signal from the Chromecast and hook it up to two cables, each going to a TV.

However, it’s important to note that this only duplicates the exact content you’re streaming. You can’t pick different media to share with each device, which is less than ideal.

Plus, your HDMI cables must be long enough to go from one room to another without breaking the connection.

Is It Possible to Connect Two Chromecast to One TV?

You can’t throw content from two Chromecasts to a single TV set. One will always catch up first and start playing, only to be interrupted once the second casting starts.

Even if both are throwing the same content, you’ll end up getting the signal from one Chromecast only, so it’s mostly a waste of time to try.
