You can watch Livestream events on your TV via Chromecast. Connect your Chromecast to one of your TV’s HDMI ports, power on your TV and select that HDMI input.
You can watch Livestream events through Chromecast using either Google Chrome desktop browser or via the Livestream mobile app. Please note these are the only applications that support Chromecast playback; mobile embeds and other browsers do not support Chromecast.
To cast the event you are watching via Google Chrome, visit livestream.com and go to the live event you are trying to view.
Open Google Chrome's Tools menu and select Cast.
Click the down arrow that appears on the top of the menu, and select Cast tab.
Next, select the name of the desired Chromecast to send the stream to your device.
After a moment, the stream will appear on your TV.
Download the Livestream mobile app from the App Store or Google Play if you haven’t done so already.
You will need a Livestream account in order to use the mobile app. Log in to your account or create a new one by selecting Continue with Email, and then Sign up.
Google provides step-by-step instructions on using Chromecast from mobile devices here.
Select a live event from the home page, or go to the navigation menu (upper right corner) to select a live event from Search, Popular, or Following.
Once you select a live event, the player will appear at the top of your screen. On the upper right corner, you will see the Chromecast icon.
Tap the icon and then select your Chromecast to start casting the stream to your TV.
The stream will appear on your TV in seconds, and you can control it through the mobile app.
Android users can also cast their screen natively depending on their device and Android OS version. See here.
