What makes it Ultra?

Picture quality up to 4K Ultra HD & HDR, stronger processing power for faster, smoother streaming than any other Chromecast device, and an optional built-in Ethernet adaptor make Chromecast Ultra a great choice for premium viewing experiences.

Your device is the remote

Use your phone, tablet or laptop¹ to play, pause and adjust the volume on entertainment that you stream to your TV. While you’re streaming, you can also multitask – take calls or send messages without interrupting what’s playing.

An app for every occasion

Catch a live sporting event. Stream some dinner party music. Or maybe make it a rom-com night. You’ll find something for every mood with countless TV shows, films, songs and more available from apps on compatible Wi-Fi-enabled Android and iOS devices.

Picture perfect

When Chromecast Ultra is paired with a 4K Ultra HD TV² and 4K content³, you’ll be amazed by the brilliant images and vibrant colours. No 4K TV? No problem. Chromecast Ultra automatically optimises for the maximum resolution that your TV can deliver.

Small size, big performance

A powerhouse processor gets your entertainment playing fast – and with reliable video performance. For tricky Wi-Fi situations, switch to the optional built-in Ethernet adaptor to enjoy high-quality wired streaming.

Setup is easy

1. Plug Chromecast Ultra into the power source and your TV's HDMI port, then select the HDMI input on your TV.

2. Download the Google Home app and follow the instructions.

3. Open a Chromecast-compatible app and tap the Cast button.

Hey presto – your entertainment goes from the small screen to the big screen.
