Chrome: Google Chrome can send any web page to your Chromecast. If you want to close the tab on your computer, though, the content won’t refresh. DashCast updates the page so you’ll have the latest content.
After you plug in the link to DashCast, you can set how often you want the page to refresh. Then, just close Chrome. It’s perfect for constantly changing content like news, weather or sports, and it won’t bog down your computer the way casting a Chrome tab would.
