Edit Chromecast Background: Change Backdrop Photos

You can change the Chromecast background (the photos shown on your TV when idle) through the Google Home app. Open the app, select your device, tap the settings gear, then choose your preferred ambient mode source—from Google’s curated art to your own photo albums.

What Is Chromecast Ambient Mode?

When your Chromecast is not actively casting, it enters a low-power idle state called Ambient Mode. This mode displays a rotating slideshow of images, along with useful information like the time, weather, and your personal photos. By default, it shows artwork selected by Google from its curated collection, but you have control over what appears. The background is not fixed—you can personalize it to show your own photos, experiment with different art categories, or even display a custom clock face. This feature is available on all Chromecast devices, including the older dongles and the newer Chromecast with Google TV, although the steps vary slightly depending on your device and the version of the Google Home app you are using.

How to Change the Background on a Chromecast (Google TV)

If you have a Chromecast with Google TV, the process is slightly different because it uses a full operating system. Here is how to change the ambient background:

1. Press the Home button on your remote to go to the main screen.
2. Select the gear icon (Settings) in the top-right corner.
3. Scroll down and select System.
4. Choose Ambient mode.
5. Here you can select Personal photos and choose a Google Photos album, or pick from Experiment styles like weather, clock, or minimal art.

Note that on Google TV, the options are more limited than on the classic Chromecast. You cannot choose specific art categories like “Fine Art” or “Satellite” images; you are limited to your own photos or the built-in experimental styles.

How to Change the Background on a Classic Chromecast (via Google Home App)

For the classic Chromecast (1st, 2nd, 3rd gen, and Chromecast Ultra), you use the Google Home app on your phone or tablet:

1. Open the Google Home app and make sure your phone is on the same Wi-Fi network as your Chromecast.
2. Tap the Devices icon (the one that looks like a monitor) at the top of the screen.
3. Find your Chromecast device and tap on it.
4. Tap the Settings gear icon in the top-right corner.
5. Scroll down to Ambient mode.
6. Choose from the options below.

Ambient Mode Options on Classic Chromecast

• Google Photos: Select a specific album or create a new one. You can choose from albums you have created in Google Photos, or create a new album with the photos you want to display.
• Art Gallery: Choose from Google’s curated collection, including categories like “Featured,” “Fine Art,” “Satellite,” “Street Art,” and “Earth.”
• Experimental: This includes weather, clock, and other minimalist styles.
• Custom: You can upload your own photos directly from your phone, but this is limited to a single image at a time.

How to Use Your Own Photos as the Background

Using your own photos is the most popular way to personalize your Chromecast. Here’s how to set it up:

1. Open the Google Home app and select your Chromecast device.
2. Tap the Settings gear and then Ambient mode.
3. Tap Google Photos.
4. If you have not already, you will be prompted to link your Google Photos account.
5. Select an existing album or create a new one by tapping the “+” icon.
6. Choose the photos you want to display and tap Done.

Your Chromecast will then cycle through the photos in that album. You can also choose to show photos from all your albums, but that can result in a chaotic slideshow, so it’s better to curate a specific album.

Common Problems and How to Fix Them

Sometimes the background won’t change, or your photos don’t appear. Here are the most common issues and solutions:

• Photos not appearing: Make sure the album is set to “Shared” or “Public” within Google Photos. If the album is private, the Chromecast might not have access to it. Open the album in Google Photos, tap the three-dot menu, and select “Options” to change sharing settings.
• Background stuck on default: This often happens after a Chromecast restart. Go back to the Google Home app, re-select your preferred ambient mode, and make sure you tap “Set as default” if the option is available.
• Changes not saving: Force-close the Google Home app and reopen it. Also ensure your phone and Chromecast are on the same Wi-Fi network.
• No “Ambient mode” option: If you don’t see the Ambient mode option in settings, your Chromecast might be running an older firmware. Check for updates in the Google Home app under device settings.

How to Turn Off the Background (or Use a Blank Screen)

If you prefer a blank screen or want to turn off the slideshow entirely, you can do that as well. On the classic Chromecast, go to Ambient mode in the Google Home app and select Experimental > Blank. This will show a solid black screen when idle. On Chromecast with Google TV, go to Settings > System > Ambient mode and choose None or Off. Note that turning it off completely may not be possible on all models; some will still show a default clock.

Comparing Chromecast Background Options

Here’s a quick comparison of the different background sources:

• Google Photos: Most personal and customizable. You can display family photos, travel pictures, or any image you like. The downside is that you need to curate an album.
• Art Gallery: Great for discovering new art and photography. It’s curated by Google, so it’s always high quality. You can’t control exactly which images appear, but you can choose a category.
• Experimental: Includes weather, clock, and other functional screens. These are useful if you want to glance at the time or weather, but they are not visually rich.

Frequently Asked Questions

Can I use a single photo as my Chromecast background?

Yes, you can. In the Google Home app, go to Ambient mode > Custom > Upload a photo. You can upload a single image from your phone. However, it will only display that one image, not a slideshow. If you want a slideshow, you need to create an album with multiple photos.

Why are my photos not showing up on the Chromecast?

This is usually a sharing or album permission issue. Make sure your Google Photos album is set to “Shared” or “Public.” Also, check that the album is not empty and that the photos are in a format supported by Chromecast (JPEG, PNG, etc.). If you’re still having trouble, try removing the album and re-adding it.

Does changing the background affect casting performance?

No, the background is only displayed when the Chromecast is idle. It does not affect casting performance or streaming quality. The Chromecast uses a separate process for ambient mode, so it won’t interfere with your streaming.

Can I set a different background for each Chromecast in my house?

Yes, you can. Each Chromecast device has its own settings. In the Google Home app, select the specific device you want to configure and change its ambient mode settings individually. You can have different albums or art categories on each TV.

Will the background change if I use a different Google account?

Yes, the ambient mode settings are tied to the Google account that is linked to the Chromecast in the Google Home app. If you switch accounts, the background will change to the settings associated with that account. You can change the linked account in the Google Home app under device settings.
