General FAQs

Having trouble with your Chromecast? Don't worry, your question may be answered below. If your questions isn't covered, please try to troubleshoot your issue.

Setup and settings

Why won't the USB cable I use for my other devices work on Chromecast?

Chromecast isn't guaranteed to work with general cables. We recommend that you use the cables and adapters provided with the Chromecast for optimal performance.

I can't tell which of my devices need to be set up.

Whenever Chromecast finds a new device in the area, it will display the Found New Device card that lets you know a new device is available to be set up.

My Chromecast won't fit into my TVs HDMI port. What do I do?

If you're using a Chromecast (1st gen) device, try using the HDMI extender that came in the Chromecast box. The extender may also improve your Wi-Fi reception.

I can't see the Chromecast home screen on my TV after setting up Chromecast.

You're likely using the incorrect input. Simply press the Input or Source button on your TV’s remote control to change the input until you see the Chromecast home screen.

How does my Chromecast receive updates?
Chromecast updates are rolled out gradually to users and your device will update automatically. Once an update is available, it can take up to two weeks for it to reach your device. It’s important that your Chromecast is plugged into wall power and connected to your wireless network during this time. You can follow the steps below to try and activate an available update if you think your device may be eligible:
  • Leave your Chromecast plugged in and connected to your WiFi network for at least one minute.
  • We recommend that you plug your Chromecast into wall power using the USB power cable and power adapter that was provided in the box.

After one minute, reboot your Chromecast device by following the steps below that match the sender device you’re using:

  • Mobile Device: Open your Google Home app > Select your Chromecast device card > Tap the Menu button in the top right corner > Tap Settings > Tap the more button in the top right corner > Tap Reboot.
  • Computer: Open your Google Home app > Click “Settings” next to your Chromecast device > Click "Reboot Chromecast"
Can I move Chromecast to a new TV?
Yes, Chromecast was built with portability in mind. You can move it from room to room for use with other HDMI enabled display devices. You won’t need to set up your device again, as long as your Chromecast is connected to the same WiFi network, you'll be able to Cast right away.
I've already set up my Chromecast. How can I change the WiFi network my Chromecast is connected to?
To change the Wi-Fi network connected to a Chromecast device, follow the steps below:
  1. Open the Google Home app.
  2. Tap the DEVICES tab to see your available Chromecast devices. 
  3. Scroll to find the device card for the Chromecast device you'd like to connect to a different Wi-Fi network.
  4. In the top right corner of that Chromecast device card, tap the device card menu  > Device settings > Network > Forget this network > Forget Wi-Fi network. 
  5. You'll need to set up your Chromecast device again on a new network.
Can I take Chromecast with me to use when I travel?
Yes, Chromecast was built with portability in mind. You can bring it with you when you travel, but keep in mind that you will need WiFi access to set up and use Chromecast.
Please keep in mind: Chromecast only works with networks which allow device to device communication. If the router/network on which you’re attempting to set up Chromecast has AP or client isolation enabled (typical of hotel rooms, school networks, corporate environments), you will not be able to set up your Chromecast device properly. You will need to disable AP or client isolation on your router in order to set up Chromecast. If you need assistance disabling AP or client isolation on your router, please contact your router manufacturer.
How can I name or rename my Chromecast?
During setup you have the ability to ‘name’ your Chromecast in order to distinguish it from others, for example 'Lulu’s Chromecast' or 'Living Room'. You can also rename your Chromecast at a later time from the Chromecast setup app.
Does Chromecast support Dolby® Digital Plus?
Dolby® Digital Plus (E-AC-3) audio technology streams are supported for use with Chromecast if the content already contains Dolby Digital Plus streams and Dolby Digital Plus pass-through is supported by your TV or Audio Video Receiver.

Please note: A number of TVs will not pass through Dolby Digital Plus streams. The Chromecast will need to be plugged directly into an A/V receiver in order for Dolby Digital Plus streams to work properly.

Casting

I’m trying to cast music from Spotify but can’t find the Cast icon in its usual place. Where is it?
Typically the Cast icon is in the top right corner of Cast-enabled apps. For Spotify, you’ll find the Cast icon at the bottom of your screen below the Play button. Tap Devices Available to see your available devices. Choose the device you want to cast to. Here's more on how to cast from Spotify.
How do I stop casting from Spotify?
To stop casting from Spotify, Tap Devices Available and select the first device in the list (For example: This iPhone or This Phone). You should now only hear music from your local device and not on your speakers.
I can't find my Chromecast extension. Where did it go?
If you've used the Chromecast extension before but it seems to have disappeared, check out these troubleshooting tips that may help it reappear.
If you've never installed the extension, here's how to get started with the Google Cast extension. 
Can I use Cast while in Chrome incognito mode?
Yes. To use Cast in Chrome incognito mode, type chrome://extensions into your browser bar, locate the Google Cast extension, and select ‘Enable in incognito’.
What's so great about Cast-enabled sites?
While casting a site's tab works well, there are numerous benefits to using controls provided by the site instead of just casting the tab for that site. Here are all the benefits to using a Cast-enabled site vs. casting a tab.
Can I cast my Android screen while in "Power Save Mode"?
Please turn off "Power Saving Mode" for the Android device you're using to cast content. Enabling "Power Saving Mode" can limit the processing power of that device which could affect the performance of the Cast Screen feature.
Can two people with compatible devices and apps cast to the TV at the same time?
Multiple users can cast to the TV provided they are both using Cast-enabled apps and are on the same WiFi network. The only way to prevent others from casting to your TV would be to password protect your WiFi network.

What is CEC?
CEC, or Consumer Electronics Control, allows for HDMI devices to be controlled with one remote control. If your television has CEC support, you may be able to turn on and change the input on your TV using your phone, tablet or computer while using Chromecast. Please note that in order for CEC to work (if CEC is supported by your TV), your Chromecast must be powered by a power outlet.
Manufacturers often call CEC by different names, including Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA Sync (Sony), HDMI-CEC (Hitachi), CE-Link and Regza Link (Toshiba), SimpLink (LG), HDAVI Control, EZ-Sync, VIERA Link (Panasonic), EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
What is HDMI?
Chromecast requires a display device that has an HDMI input, which is common in newer TVs. HDMI stands for High-Definition Multimedia Interface. Inside the Chromecast box, you will find an HDMI extender which is not required for use with Chromecast, but can be used if your Chromecast does not fit directly into your TV. It may also be used to improve your WiFi reception. The HDMI extender should be connected to your TV and your Chromecast.
