Chromebooks are a great choice for students and busy professionals who want to stay connected while on the go. However, if you’re not careful, you can disable your Chromebook’s screen when it’s connected to an external display. To do this, you’ll need to know how to connect your Chromebook to an external display and disable its screen. To connect your Chromebook to an external display, first make sure that it is turned on and connected to the internet. Then open the Chrome browser and type chrome://display/connections in the address bar. Once you’ve found the connection that corresponds to your Chromebook, click on it and select “enable.” After enabling the connection, you’ll need to set up a password for your external display. To do this, open the Chrome browser and type chrome://settings/security/password in the address bar. After setting up your password, click on “enable.” Now that your Chromebook is enabled with a connection and password, you can disable its screen by clicking on “disable.” After disabling your Chromebook’s screen, be sure that you’re logged into it so that you can continue using it as usual.


There are two ways to use a Chromebook with an external display. The extra display can be a secondary screen independent of the Chromebook display, or you can mirror your Chromebook’s display.
