Make Slideshow Chromecast: Step-by-Step Guide

To Chromecast a slideshow from your phone or computer, open the photos app or Google Photos, select the images you want, tap the Cast icon, and choose your Chromecast device. The slideshow will then play on your TV, with playback controls on your device. This guide covers the exact steps for Android, iPhone, Windows, and Mac, plus how to fix common casting problems.

What You Need to Cast a Slideshow

Before you start, make sure you have the following:

• A Chromecast device (Chromecast, Chromecast Ultra, Chromecast with Google TV, or a TV with built-in Chromecast) plugged in and powered on.
• Your phone, tablet, or computer connected to the same Wi-Fi network as the Chromecast.
• The Google Home app installed on your phone or tablet (for setup and troubleshooting).
• A photo app that supports casting, such as Google Photos, Microsoft Photos, or the default gallery app on your device.

How to Cast a Slideshow from Android or iPhone

The most reliable way to cast a slideshow from a mobile device is through the Google Photos app. Here’s how:

1. Open the Google Photos app on your Android or iOS device.
2. Tap and hold to select the photos you want in the slideshow. You can select multiple photos from your library.
3. Tap the Cast icon (a rectangle with Wi-Fi waves in the corner) at the top of the screen.
4. Choose your Chromecast device from the list.
5. The selected photos will start playing as a slideshow on your TV. Use the on-screen controls to pause, skip, or adjust the speed.

If you don’t see the Cast icon, make sure your device is on the same Wi-Fi network as the Chromecast. Also, some third-party gallery apps have their own cast button, but Google Photos is the most consistent.

How to Cast a Slideshow from Windows or Mac

On a computer, you can cast a slideshow using the Chrome browser or the Google Photos website.

1. Open Google Chrome and go to photos.google.com.
2. Sign in to the Google account that has your photos.
3. Select the photos you want by clicking the checkmark in the top-left corner of each photo.
4. Click the Cast icon in the top-right of the browser toolbar (or right-click a selected photo and choose “Cast to device”).
5. Select your Chromecast.
6. The slideshow will start playing in a new tab or directly on your TV, depending on your settings.

Alternatively, you can cast your entire screen (including a PowerPoint or Keynote slideshow) by clicking the three-dot menu in Chrome, selecting “Cast,” and then choosing “Cast desktop” or “Cast tab.” This is useful for presentations.

Using the Google Home App to Cast Photos

The Google Home app also lets you start a slideshow directly from your phone, even if the photos are stored on the device itself.

1. Open the Google Home app.
2. Tap your Chromecast device.
3. Tap “Cast my screen” or “Cast photos.”
4. If you choose “Cast photos,” you can select a source (Google Photos or your device) and then pick an album or individual photos.
5. The slideshow will begin on your TV.

Common Problems and How to Fix Them

If casting doesn’t work, try these troubleshooting steps:

• No Cast icon: Ensure your phone and Chromecast are on the same Wi-Fi network. Restart the app or your device.
• Slideshow stops after one photo: Some apps only cast a single image. Use Google Photos or the Google Home app for continuous playback.
• Audio not playing: If your slideshow includes videos, make sure the volume on your TV and casting device is up. Some apps mute video audio during slideshows.
• Lag or buffering: Move your router closer to the Chromecast, or reduce the number of devices on your network. Also, close other apps that might be using bandwidth.
• Device not found: Restart your Chromecast by unplugging it for 30 seconds, then plugging it back in. Also, restart your router.

Tips for a Better Slideshow Experience

To make your slideshow more enjoyable, consider these tips:

• Create an album in Google Photos before casting. This makes it easier to select all photos at once.
• Adjust the slideshow speed using the controls on your phone or computer. Some apps let you set a duration per photo.
• Use ambient mode on your Chromecast to display photos from a Google Photos album when idle. You can set this up in the Google Home app under Device Settings > Ambient Mode.
• For presentations, use the “Cast tab” feature in Chrome to mirror a PowerPoint or Google Slides presentation, including transitions and animations.

Alternatives to Chromecast for Slideshows

If you don’t have a Chromecast, other options exist:

• Smart TV apps: Many smart TVs have built-in apps like Google Photos or Plex that can display slideshows directly.
• HDMI cable: Connect your laptop or phone to the TV with an HDMI cable (using an adapter for phones). This is the most reliable and doesn’t depend on Wi-Fi.
• AirPlay (Apple TV): If you have an Apple TV, you can use AirPlay to mirror your iPhone or Mac screen and play a slideshow.
• DLNA: Some TVs and media players support DLNA, allowing you to stream photos from a computer using apps like Plex or Serviio.

Frequently Asked Questions

Can I cast a slideshow from my iPhone to Chromecast?

Yes, you can use the Google Photos app on iOS to cast a slideshow. The process is the same as on Android: select photos, tap the Cast icon, and choose your Chromecast. Note that iOS doesn’t support screen mirroring to Chromecast natively, so using an app like Google Photos is the best method.

Why won’t my Chromecast play a slideshow from my gallery?

Most default gallery apps on Android and iOS don’t have a built-in cast button. They may only cast a single photo. To play a slideshow, use Google Photos or the Google Home app, which are designed to handle multiple photos and continuous playback.

Can I cast a slideshow from PowerPoint?

Yes, you can cast a PowerPoint presentation by using the “Cast tab” feature in Google Chrome. Open the presentation in PowerPoint Online or in the desktop app, then select Cast from the Chrome menu and choose “Cast tab.” Your entire screen will be mirrored, so the slideshow will appear on the TV.

How do I stop a slideshow on Chromecast?

You can stop the slideshow by tapping the Cast icon in the app you used and selecting “Disconnect,” or by pressing the Home button on your Chromecast remote (if you have one). On your phone, you can also open the Google Home app, select the device, and tap “Stop casting.”

Does Chromecast support 4K slideshows?

Yes, Chromecast Ultra and Chromecast with Google TV support 4K resolution. When casting from Google Photos, the images are sent at their original resolution, so if your photos are 4K, they will display in 4K on a compatible TV. Older Chromecast models only support 1080p.
