Yes, you can connect a Chromebook to a TV with HDMI. Most Chromebooks lack a full-size HDMI port, so you’ll need a USB-C to HDMI adapter — plug it into your Chromebook, run an HDMI cable to your TV, and select the correct TV input.
- You use a USB-C to HDMI adapter that supports DisplayPort Alt Mode
- Your TV is on and set to the correct HDMI input
- Your Chromebook’s USB-C port supports video output
- You configure the display in Chromebook Settings
- Your USB-C cable or adapter does not support video
- The TV input is set to the wrong HDMI port
- Your Chromebook shows a “Cable may not support displays” error
- The adapter is a charge-only USB-C cable with no Alt Mode
What You Need for a Chromebook HDMI TV Connection
Most Chromebooks ship with USB-C ports only — no full-size HDMI. That means a USB-C to HDMI adapter is the missing link. The adapter must support DisplayPort Alt Mode, which is what carries video over USB-C. A basic charging cable will not work here.
If you’re unsure whether your port handles video, check out our guide on whether USB-C supports video before buying an adapter.
Step-by-Step Setup
- Plug your USB-C to HDMI adapter into the Chromebook’s USB-C port
- Connect an HDMI cable from the adapter to an available HDMI port on your TV
- Use your TV remote to select the correct HDMI input (e.g., HDMI 2)
- On the Chromebook, go to the clock area > Settings > Displays
- Choose Mirror Built-in Display to duplicate your screen, or leave it to extend
For full setup guidance, Google’s official Chromebook display help page covers every display option in detail.

Troubleshooting: When the TV Shows Nothing
If your TV stays blank, the most common culprit is an adapter that doesn’t support video. You may see a “Cable may not support displays” warning on the Chromebook. Swap the adapter for one explicitly rated for video output.
Wrong TV input is the second most frequent issue — double-check that your remote is selecting the exact HDMI port the cable is plugged into. If you still get no signal, our USB-C to HDMI not working troubleshooting guide walks through every fix step by step.
Bottom line: A chromebook hdmi tv connection is straightforward once you have the right USB-C to HDMI adapter — one that supports DisplayPort Alt Mode. Get that part right, select the correct TV input, and your Chromebook display will appear on screen within seconds.
