Yes, you can cast from a laptop to Chromecast using Chrome browser
You can send video, tabs, and your entire screen from a Windows or Mac laptop to any Chromecast device using Google Chrome. The feature is built into Chrome and works over the same Wi-Fi network — you do not need to install anything extra or pay for a service. Casting takes about three seconds once you start the process.
The catch is that your laptop and Chromecast must be on the same Wi-Fi network. If your Chromecast is on your home network and your laptop is on a guest network, casting will not work. Some workplace networks block Chromecast entirely, so check with your IT department if you are at an office.
Casting from a Mac works the same way as Windows, and the steps are identical. You do not need to own the Chromecast — you can cast to any device on your network, including one at a friend's house or in a hotel room.
Key Takeaways
- Open Chrome, click the three-dot menu, select "Cast", choose your Chromecast device, and pick what you want to send: a tab, all tabs, or your whole screen.
- Casting a single tab uses less bandwidth and battery than casting your entire screen, and the tab keeps playing even if you switch to another window.
- Your laptop and Chromecast must be on the same Wi-Fi network; if they are not connected to the same network, the device will not appear in the Cast menu.
- Casting stops when you close the tab or click "Stop casting" in the Cast menu; the Chromecast does not keep playing after you disconnect.
- Some video sites block casting for licensing reasons, so not every video will work even if your setup is correct.
How to cast a tab or video from your laptop
Open Google Chrome and navigate to the video or content you want to cast. Click the three-dot menu in the top right corner of the browser window. Select "Cast" from the dropdown menu.
A panel will appear showing all Chromecast devices on your network. Click the device you want to use. A second panel will ask what you want to cast: "Cast tab", "Cast all tabs", or "Cast desktop". Choose "Cast tab" for a single video or webpage. The content will appear on your TV or display within a few seconds.
While casting a tab, you can minimize Chrome, switch to other windows, or even close other tabs — the cast will keep playing. If you close the tab that is casting, the video stops when ready.
Casting your entire screen versus a single tab
Casting a single tab sends only that one browser window to your Chromecast. This uses less Wi-Fi bandwidth and drains your laptop battery more slowly than casting your whole screen. If you are watching a video and want to check email or browse the web on your laptop at the same time, cast a tab.
Casting your entire screen sends everything on your display to the Chromecast, including your taskbar, desktop icons, and any windows you have open. This is useful if you want to show a presentation, share a document, or display something that is not in a browser. Screen casting uses more power and bandwidth, and your laptop performance may slow down slightly.
If you choose "Cast all tabs", every tab in your Chrome window will appear on the Chromecast, and you can switch between them using your laptop keyboard. This is rarely the right choice — "Cast tab" is usually what you want.
Why your Chromecast is not showing up in the Cast menu
The most common reason is that your laptop and Chromecast are not on the same Wi-Fi network. Check that both devices are connected to the same network name. If your router has a 2.4 GHz and 5 GHz network with different names, make sure both devices are on the same one — Chromecast devices often work better on 2.4 GHz.
Restart your Chromecast by unplugging it for 10 seconds and plugging it back in. Then restart Chrome or close and reopen the Cast menu. If the device still does not appear, restart your Wi-Fi router and wait a minute for everything to reconnect.
Some workplace and school networks block Chromecast or do not allow devices to communicate with each other. If you are on a corporate or institutional network, contact your IT support to ask whether Chromecast is supported. Guest networks often have the same restriction.
Video sites that block casting and what to do instead
Netflix, Disney+, HBO Max, and some other streaming services intentionally block casting from Chrome tabs for licensing reasons. When you try to cast, the video will not appear on your Chromecast even though the tab is casting.
These services have their own Chromecast buttons built into their apps. Open Netflix or Disney+ in Chrome, start playing a video, and look for a Chromecast icon (usually in the top right or bottom right of the video player). Click that icon instead of using the Chrome Cast menu. The video will cast directly from the service to your device.
If a video site does not have a built-in Chromecast button and does not allow tab casting, cast your entire screen instead. This sends everything on your display to the Chromecast, including the video player. Screen casting works for almost any video, but it uses more power and bandwidth.
Casting from Chrome on different operating systems
The casting process is identical on Windows and Mac laptops. Open Chrome, click the three-dot menu, select "Cast", and choose your device. There are no extra steps or different options between the two systems.
Chromebooks (laptops that run Chrome OS instead of Windows or Mac) also cast the same way. The steps are the same, and Chromebooks often cast more smoothly because they are built around Chrome.
Linux laptops can cast using Chrome if you have installed it, and the process is the same. Some Linux distributions may have Wi-Fi or network issues that prevent Chromecast from working, but the casting feature itself functions identically.
Controlling playback and stopping the cast
While a tab or screen is casting, you control playback from your laptop. If you are watching a video, use the play, pause, and volume controls in the Chrome video player — these work normally. The Chromecast itself does not have a remote control for browser content (though some Chromecast models have a physical remote for other functions).
To stop casting, click the three-dot menu in Chrome and select "Cast" again. The Cast panel will show your device with a "Stop casting" option. Click it, and the video will stop when ready. You can also close the tab that is casting, and the stream will end.
If you want to cast to a different device, open the Cast menu and click a new device. The cast will switch to that device without you having to stop the first one.
Frequently Asked Questions
Do I need to install anything to cast from my laptop?
No. Google Chrome has casting built in. If you have Chrome installed and a Chromecast device on your network, you can cast when ready. No extensions, apps, or downloads are required.
Can I cast from Firefox or Safari?
No. Casting from a laptop browser works only in Google Chrome. Firefox and Safari do not have this feature. You can still cast from phones and tablets running Android or iOS using their respective apps.
Will casting work if my Chromecast is on a different Wi-Fi band?
Not usually. If your router broadcasts both 2.4 GHz and 5 GHz networks with different names, your laptop and Chromecast must be on the same one. Most Chromecast devices work better on 2.4 GHz. Check your router settings to see which band each device is connected to.
What happens to the cast if I close my laptop?
The cast stops when ready. Chromecast does not store or buffer content — it receives a stream from your laptop. If your laptop shuts down, loses power, or disconnects from Wi-Fi, the video stops.
Can I cast audio only without the video?
No. Casting from Chrome sends both video and audio together. If you want to cast only music or audio, use a music streaming service that has a built-in Chromecast button, such as Spotify or YouTube Music.
