In this post, we’ll explain how to Extend Your Desktop Using Chromecast. Google Chromecast is one of the simplest and easiest ways to use your devices to watch videos on your TV. With this device, you can easily watch videos on streaming websites even if you don’t have a smart TV.
But from the small screen to the big screen. It’s also the main idea behind it. With an Android device, an iPhone, Mac, iPad, Windows PC, or Chromebook, you can use Google Chromecast to watch what’s on your screen. “Mirroring” means that your screen on your PC or Android device is shown on another device in the same way.
Not only can you monitor your desktop wirelessly, but you can also make it bigger. In some situations, this can be more important. But when you open a new screen to use as a second desktop, you are using the whole new screen.
Ways To Extend Your Desktop Using Chromecast
Cast Desktop to TV with Chromecast
It’s easy to cast your computer screen; just make sure that your computer and Chromecast device are both connected to the same WiFi network. Chromebooks, Mac, and Windows all let you show the whole computer screen. Just do these simple things:
- On your computer, launch Chrome.
- Click the three dots icon at the top right of the screen and click Cast.
- Next to Cast to, click the drop down arrow, and select Cast desktop.
- Choose your Chromecast device where you want to watch the content.
- When you are finished, simply click Stop Casting.
Extend Desktop with Chromecast
This step-by-step guide has pictures from Windows 11. But this way of making your screen bigger also works with Windows 10.
- From the Start menu, select “Settings.” (An alternate route is to right-click on “Display Settings” on your desktop as a shortcut to get into System > Display.)
- In Settings, go to “System (Display, notifications, apps, power).”
- Once in Display, click on Detect. Here, we are going to trick Windows into thinking there’s a secondary display already attached, even though it isn’t. It says “Display not detected,” but shows a blue screen—click on it.
- Go down to “Multiple displays” and click the drop-down box. Then, select “Try to connect anyway on VGA.”
- Select display 2. In the drop-down box, select “Extend these displays.” Click the “Apply” button. A message will pop up and say, “Keep these display settings?” Click the “Keep changes” button.
Now you can use your Google Chrome browser and Chromecast on the second screen to make your desktop bigger.
- Open Google Chrome on your desktop.
- Before you can connect to your Chromecast by clicking the Chromecast icon in the upper-right corner of your Chrome browser, you need to click the small arrow on the Chromecast icon area. Scroll down to “Cast screen/window (experimental)” from there. Then choose it.
- As the “Cast screen/window,” choose the second display, which is the one we just made Windows think we have. Now, your Windows desktop should be visible on both your computer and your TV.
Extend Desktop Using Chrome
Using Chrome’s built-in Chromecast service is the easiest way to extend your desktop on both Windows and Mac. Since Google made both the Cast protocol and the most popular browser in the world, it’s easy to combine the two to make a wirelessly-extended display.
You’ll need to download and install the latest version of Google’s Chrome browser on your computer in order to cast to your Chromecast. Chrome now comes with support for Chromecast built in.
- Click on the menu button in Chrome, then select Cast from the dropdown menu.
- Once the “Cast to” box opens, select the drop-down arrow. You’ll be presented with two choices: “Cast tab” or “Cast desktop.”
- Choose “Cast desktop.” You’ll be returned to the main Chromecast selection box.
- Next, select your Chromecast device. Ours keeps telling us it’s “Unable to mirror system audio” at this time.
- Another box pops up on the screen, asking, “Do you want Chrome Media Router to share your screen?” Click on the “Yes” button.
- Your Mac desktop should now be extended to where your Chromecast device is plugged in.
