How to Screen mirror Chromebook to your smart TV

One of the cool features with Chromebooks is the ability to effortlessly cast your computer screen to your TV. Screen casting or mirroring is built-in to the Chrome browser which Chromebooks are primarily centered around. With this feature, you can display your Chromebook’s entire display, a chrome tab or supported media app to the big screen wirelessly. You don’t need cables.

Before you cast your Chromebook wirelessly to your TV, you need to make sure that you meet the following requirements;

  • Your Chromebook and TV must be connected to the same WiFi network.
  • You might need to turn off VPN on your computer first.
  • Your TV must have Chromecast support. Usually that means the TV has Chromecast built-in which is common with most Android Smart TVs. Alternatively you must have a streaming device with Chromecast support connected to your TV. Common devices include Google Chromecast, Xiaomi Mi Box, Nvidia Shield, TiVO etc. Other platforms such as Roku or Amazon Fire TV Stick with miracast will only support casting content from specific video sites such as Netflix, Youtube, Disney+ etc, but not Chrome browser tab or entire display.

With that said, sharing your Chromebook’s entire screen, chrome tab or specific video website/app is done from the Chrome browser itself. To cast only a Chrome browser tab, open Chrome, select menu (3 vertical dots), then click on cast.

Click on Chrome browser menu > cast

A list of supported displays/streaming player/smart tvs will appear on a pop-up window as being available. For my case, you can see “Living room TV” which is the name for my Google Chromecast with Google TV streaming player. My TCL Roku Smart TV appears too.

Available display devices

As you tell, casting to the Roku is only available for specific video sites such as Youtube, Netflix. So I can’t cast a standard Chrome browser tab or the laptop’s entire display to the TV. That’s because Roku TVs and streaming players don’t have Google’s proprietary Chromecast protocol built-in. Instead they have Miracast, the WiFi-alliance developed standard which is different from Chromecast and more recently Apple AirPlay. That also includes other big Smart TV names such as Samsung and LG.

Alright, so I selected Living room TV since it’s my Google Chromecast device. If all goes well, you should see the Chrome browser tab you mirrored on the big screen. A blue cast icon will also now appear on your Chrome browser indicating that a tab is being displayed on another screen.

To stop casting, tap on the blue cast icon, then click the display you mirrored to. Your Chromecast-compatible device will return to its home page.

You can also cast your Chromebook’s entire display to the big screen. That means any Chrome browser tab or installed apps will be showing on the screen. This is particularly helpful for displaying Apps that natively don’t have Chromecast support such as text editors, email app, file app, social media etc.

Choose between cast tab or the entire desktop

To cast the entire display, again select Chrome browser menu, then cast and then under sources dropdown button, you’ll see two options; cast tab and cast desktop. Select cast desktop and then click on the Chromecast display/device again. Now the entire Chromebook display is mirrored to the big screen.

To stop sharing your Chromebook on the big screen, select the blue cast icon and click on your Chromecast display.
