Short answer
If your Chromebook has an HDMI port, use an HDMI cable. Most recent Chromebooks without one send video through USB-C, so use a USB-C to HDMI adapter. You can also cast a tab or your whole screen to a TV with Chromecast or Google TV built in.
Find your port, get the right part
Look at the side or back of your device and pick the one that matches.

USB-C to HDMI adapter
Your laptop's USB-C port carries video and your screen takes HDMI, so a plain adapter does the job.

- Connect the Chromebook to a free HDMI port on the TV.
- Switch the TV to that HDMI input.
- To choose mirroring or a separate screen, open Settings, then Device, then Displays.
Check this first
- To cast without a cable, the TV needs Chromecast or Google TV built in, or a Chromecast plugged in, on the same Wi-Fi.
Questions people ask
How do I cast my Chromebook to a TV?
In Chrome, open the menu (three dots), choose Cast, and pick the TV. You can cast one tab or your whole screen.
The picture works but there is no sound on the TV. Why?
HDMI carries sound, but the computer may still be using its own speakers. On Windows, click the speaker icon and pick the TV. On a Mac, open System Settings, then Sound, and choose the TV under Output.
