How to Cast a Chrome Tab to Your TV

Same Wi-Fi network, a few clicks, and your tab is on the big screen.

  1. Connect your computer and TV (or Chromecast) to the same Wi-Fi

    Make sure the computer you are casting from and the TV are connected to the same router's Wi-Fi network.

  2. Click the three-dot menu in the top-right of Chrome

    Click the menu icon in the top-right corner of the Chrome window.

  3. Click "Cast"

    Select "Cast" from the menu that appears.

  4. Choose your TV or device from the list

    Pick the TV or Chromecast device you want to display from the list of detected devices, and the current tab appears on the TV screen.

  5. Why it is useful

    Instead of a small laptop screen, you can show a video or a presentation wirelessly on a big TV screen, with no cable connection needed.

A Cable-Free Way to Use the Big Screen

Casting a tab is often faster than plugging in an HDMI cable, especially when the TV is across the room or you just want to show something briefly during a meeting or a family movie night.

What Gets Shared Depends on What You Cast

Chrome lets you cast just one tab, your entire desktop, or a specific file, and each option behaves a little differently β€” casting a tab is generally the smoothest choice for streaming video or browsing content, while casting the whole desktop mirrors everything you do on your screen.

Frequently Asked Questions

Why can't Chrome find my TV or Chromecast device?

This almost always means the computer and the TV are not on the same Wi-Fi network, so double-check both are connected to the same router before trying again.

Does casting a tab affect video quality or add noticeable lag?

A stable Wi-Fi connection usually keeps quality good and delay minimal, but a weak or congested network can introduce a slight lag or lower resolution.
