How to Use Chromecast as a Second Monitor : Extend Your Desktop Now

What a great invention the Google Chromecast is, isn’t it? It nicely mirrors your display to another device of your choice so that you experience seamless viewing on any device that you want. You can mirror the display on to any device – Android, iPhone, Windows, MacBook, Chromebook, and more.

We already know this about Chromecast, though. What many don’t know is that we can use Chromecast as a second monitor! Just by taking care of a few settings we can extend the screen of the desktop into the second monitor and amplify our experience!

Let’s talk about how to extend the desktop in Windows 10 as well as in Mac:

Use Chromecast as second monitor in Windows 10

  1. Go to the Settings from the Start menu.
  2. Here you will see the System option, below which you have Display, Notifications, Apps, and Power.
  3. Enter the Display setting.
  4. Once the tab opens, click on Detect and click on the Blue Screen that you see. You may notice that it says Display not detected but that’s okay.
  5. Scroll and in Multiple Displays, choose Try to connect anyway on VGA in the drop-down box.
  6. Now choose the second display and in the drop-down, choose Extend these displays.
  7. Click Apply.
  8. After this, you will be asked if you want to freeze on these settings.
  9. Press Keep Changes.

The setup is all done now. You need to open Google Chrome on your desktop. On the upper-right corner, you will see the Chromecast option. Now choose Cast Screen/Window. Choose display number 2 for this. That’s about it! You have successfully made your desktop think that we have two screens!

Note that even though these settings are for Windows 10, you can follow the same steps for Windows 8. They are more or less the same.

Use Chromecast on a Window 10 desktop – after the latest Windows update

If you have updated your Windows, you may not be able to follow the aforementioned steps. A few things have changed thanks to this massive update. Luckily, you still have an option to extend your desktop with a Chromecast and here are the steps:

1. Make sure that all the required cables are connected properly. Your monitors need to be connected, of course.

2. Press the Windows Key and P simultaneously to directly choose how to display your desktop.

3. If you want to explore more options, right-click on your Desktop and choose Display Settings.

4. Here, you will see all the options of monitors available. If you don’t see your new monitors, click on Detect.

5. Go to the Multiple Displays option and select the right option from the list that appears when you click on it. Then choose to Extend Desktop.

6. After this, choose Keep Changes and scroll up to adjust the resolution. The recommended setting is the best, but if you want to make changes, feel free.

7. Click on Keep Changes again.

You are done!

Use Chromecast as second monitor on Mac

Make sure you have the latest version of Google Chrome downloaded and installed on your Mac. You will automatically have Chromecast support for it. Now, do the following:

  1. On the upper-right corner of the browser, you will see the Google Chromecast icon.
  2. Click on it to open the Cast to box.
  3. Here you will see a drop-down arrow. Click on it and choose the Cast Desktop option.
  4. You will be navigated to the Chromecast box again.
  5. Here, you must now select your Chromecast Device. You may see an error here saying it can’t mirror system audio. Soon you will see a pop-up that asks for permission for the Chrome Media Router to share the screen. Choose Yes.
  6. That’s about it!

The only catch here is that you won’t be able to listen to the audio from both devices. It will only come from your Mac, but that should be okay. It won’t make much of a difference anyway. The idea is to ensure that the desktop is extended for seamless viewing and this process helps with that seamlessly.
