Mobile devices operating system (OS) requirements
You can use the Google Home app on compatible mobile devices to set up Chromecast, Chromecast Ultra, Chromecast Audio, and TVs and speakers with Chromecast built-in.
The Google Home app is compatible with mobile devices running:

Hardware and broadband requirements
All Chromecast devices require a TV with High-bandwidth Digital Content Protection (HDCP) 1.3 or higher built in. HDCP 2.2 is required to support 4K content. Most televisions that are five years old or newer and have HDMI ports will have at least one port that supports HDCP 2.2.
In order to view 4K or Ultra HD content on Chromecast Ultra, in addition to the requirements listed above, your equipment must meet the following requirements:
- For 4K content, you need a 4K-capable TV and a high-speed internet connection (at least 20 Mbps)
- For HDR content, you need an HDR-capable TV
- Availability and performance of features and services are application-, device- and network-dependent and may not be available in all areas; subscription(s) may be required, and additional terms, conditions and/or charges may apply.
- The length of your content, your internet service provider's network availability over time and other factors can impact your Internet speed, and therefore Chromecast Ultra's ability to show content in the best possible resolution.
