Setting up your Chromecast with a TV isn’t difficult to do as the above guide shows you. After that step, you can cast a browser tab to your Chromecast television as if you had moved it to a second monitor.

Doing this is easy on Chrome. Look at the top-right of your browser window and find what looks like a Wi-Fi signal beaming toward a screen. Click this, and you’ll see all the devices that can cast your tab. Click on the one you want, and you’ll see the tab appear on the television.

But after installing and trying it, it didn’t seem to be functioning anymore. It’s worth keeping tabs on it in case it does evolve over the coming months.

Casting your desktop isn’t as intuitive as casting a tab, but it’s not difficult either.

As above, find the Chromecast icon at the top right of your browser and click it. This time, however, don’t click the screen you want to cast to; instead, click on Sources below the displays.

Then, click Cast Desktop. Once selected, you can then click the screen you want as usual.

How to Cast From a Video Service

Sometimes you want to cast a video on a webpage without casting the whole page. For example, if you’re going to put a video from YouTube through your Chromecast, you may not want the rest of the page to show—just the video.

In this situation, look for the Chromecast icon on the video player itself. You may need to hover over the video with your mouse to get the controls to appear. Then, look for the Chromecast icon and click it if you see it.

If you don’t see it, you may still be able to work around it. For example, you could try casting the tab, then making the video full screen if the player lets you do so.

What if you want to cast a media file located on your computer? Thankfully, Chromecast can handle that, too.

How to Cast From a Video Player

If you’re lucky, you’ll find that your favorite video player supports Chromecast natively. Apps such as VLC have adopted Google’s streaming device, allowing you to cast whatever you’re watching to the TV immediately.

If you’re using a recent version of VLC, you can cast to Chromecast by clicking on Playback, then hovering over Renderer.

Your Chromecast should appear on the list of renderers if it’s currently on and running. If it doesn’t, try restarting your computer’s Wi-Fi connection and trying again.

If it does appear, click on the Chromecast. Then, open the video you want to play.
