If you know how to connect a Chromebook to a TV, you can stream video content from your laptop to your home theater. It's even possible to wirelessly connect your Chromebook to a TV using Chromecast.
Information in this article applies to all Chrome OS devices regardless of the manufacturer (Acer, Dell, Google, HP, Lenovo, Samsung, Toshiba, etc.).
How to Connect a Chromebook to a TV With HDMI
If your Chromebook has an HDMI port, you can connect it to an HDTV using an HDMI cable. If your device uses USB-C instead, you'll need a USB-C adapter with an HDMI port. To connect via HDMI:
Insert one end of the HDMI cable into your Chromebook. If using an adapter, first plug the HDMI cable into the adapter, then insert the adapter into one of the USB-C ports on the side of the Chromebook.
Insert the opposite end of the HDMI cable into your TV. Look for one or more HDMI ports on the back, bottom, or sides of the screen.
Boot up your Chromebook.
Turn on the TV and set it to the proper input channel (e.g. HDMI 1, HDMI 2, etc.).
Your Chromebook's desktop should now appear on the TV. To make the entire screen visible, you may have to change some system settings. Select the clock in the bottom-right corner of the screen, then select the Settings gear.
In the Chromebook settings, scroll down to the Device section and select Displays.
Check the box beside Mirror Internal Display.
Your entire Chromebook screen should now appear on your TV. When you open apps and browse the web as you normally do, your computer's actions will be mirrored on the TV screen. That way, you can show off photos stored in your Google Drive or watch streaming video from websites like YouTube and Netflix.
