Frequently Asked Questions
Will I need a Chromecast for each TV?
Why am I not seeing all of my TVs when I click the cast buttons?
If you have setup each of your TVs with Chromecast you will next want to double check that they are all connected to the same Wifi network. If you have more than one Wifi network, you may have setup some of your TVs on a different Wifi network.
Can I cast from my tablet or phone?
You will need to cast from a laptop or desktop computer.
Are there any other options for casting to multiple TVs?
Yes. One other option is you can use an HDMI cable splitter to hook up one Chromecast to two TVs. The limitation of this option is you will need an HDMI cable running between the two TVs and the splitter will need to be plugged into a power outlet. You will also have to display the same content on the two TVs connected to the same Chromecast.
