Select thethree dots in the upper right corner of Chrome and chooseSave and share >Cast .

Your PC desktop will start casting immediately. To turn off casting, select the blue Chromecast icon at the top right of Chrome and chooseStop .

How to Cast a Chrome Browser Tab

Don’t want to cast the whole screen? Chrome lets you pick a single tab if you’d rather see just that on your TV. This method might be used to show a website on your TV or to display photos or online documents.

The steps are very similar to the above directions:

Open Chrome’sthree-dot menu at the top right and then selectSave and share >Cast .
SelectSource in the pop-up window and make sureCast tab is selected.
Choose your Chromecast from the list to start casting the active tab to your TV.

Cast Screen vs Cast Tab

These are your options when using Chromecast with a computer. They might seem similar but there’s a big difference, which matters depending on the type of content you want to cast to your TV.

The screen option casts the whole desktop. This includes the taskbar, Start menu, and any program you open during the casting session. Whether it’s Photoshop, another web browser, Microsoft Office, or Notepad — it doesn’t matter. Anything you open on your desktop or laptop will display on the TV until you shut off casting.

The tab option is much more restricted, but that can be better in some situations. The tab you’re viewing when you start casting is what will show up on the TV, and nothing else. You can browse around to different websites and as long as you don’t close the tab, each website will appear on the TV.

How to Use Google Chromecast on Android and iOS

Both options are great for sharing content with the room or using your TV as a bigger screen, but only for things that don’t move much, like text-only apps and websites. What it doesn’t work as well for is video. Well, it depends…

Casting Videos From a PC to Chromecast

Streaming video to a Chromecast works great if you’re watching a video on a website that supports casting. This is because the Chromecast will source the stream directly from that website instead of your computer. In other words, it’s no longer broadcasting from your tab or screen, but instead directly from the internet, essentially turning your computer into a remote.

YouTube is one example of a site that can do this, but there are lots of other ones. To check, look for the cast icon somewhere in the video player. On YouTube, it’s along the bottom right. Select that button and then choose your Chromecast to watch the video on your TV.

You’re more than welcome to_try_ to watch a movie by casting your desktop or tab, but it probably won’t run as smoothly as you hope. To do this, simply follow the steps above for whichever method makes the most sense. If the movie is playing in a video player like VLC, you’ll need to cast your desktop, otherwise, pick the tab option.

Why Cast?

Google’s streaming device is an affordable alternative to set-top boxes like Apple TV and Roku. Primarily, it allows you to view all kinds of content on a TV, including YouTube, Netflix, video games, and Facebook videos.

Chromecast also makes it incredibly easy to connect your computer to a TV because all you need is Chrome. This feature works with the Chrome browser on any PC platform that supports it including Windows, Mac, Linux, and Google’s Chrome OS.
