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.

Can I move Chromecast to a new TV?
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 in at the wall and connected to your wireless network during this time. You can follow the steps below to try to activate an available update if you think your device may be eligible:
- Leave your Chromecast plugged in and connected to your Wi-Fi network for at least one minute.
- We recommend that you plug your Chromecast in at the wall using the USB power cable and power adaptor 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"

How can I name or rename my Chromecast?
Please remember: 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 or a captive portal (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.
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.

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 for Dolby Digital Plus streams to work properly.

I'm a developer interested in developing for Cast and/or Chromecast. Where can I find more information?
What is CEC?
If you're a developer interested in finding out more about developing for Cast and/or Chromecast, please visit developers.google.com/cast
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).

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 Wi-Fi reception. The HDMI extender should be connected to your TV and your Chromecast.
