How to use Chromecast to stream your Windows or Mac desktop
When you need to display an application on your TV that doesn’t have built-in Chromecast support, it’s possible to display your PC or Mac’s entire desktop.
Google calls the feature “experimental” but, in our experience, it works pretty well for showing off photos, web pages, and content hosted in applications outside Chrome. It’s just as easy as anything else to do with Chromecast.
To cast your entire desktop, follow these steps:
- Open the Google Chrome browser on your computer
- Tap the Menu option in the upper right-hand corner (looks like a red circle with white arrow)
- Click ‘Cast’
- Select ‘Cast Desktop’ from the dropdown menu that appears
- Select your Chromecast device
- Click to share your screen and audio if you’d like.
- Minimize Chrome if it’s in your way, but do not close it.
To stop Casting do this:
First, stop casting by clicking the Google Cast extension and clicking the “Stop casting” button.
Click the Cast button again and then the small triangle in the top-right corner. Pick the “Cast screen/window (experimental)” option, select your Chromecast and you’ll be asked if you “want Google Cast to share your screen”.
On the next menu select your Chromecast. A pop-up box will appear: choose Entire screen, click the Share button and your computer’s desktop will appear on your TV.
While your screen is being shared in this way, you’ll also see a small alert box at the bottom of your laptop or PC screen reminding you that you’re still sharing its contents. You can use this box to stop casting at any time, or simply hide it.
