Yes, you can cast your laptop to your TV using Chromecast
You can send your laptop screen to a TV with a Chromecast device plugged into it. The method depends on what operating system your laptop runs. Windows, Mac, and Linux laptops all work, but the steps differ slightly. Your Chromecast and laptop must be on the same Wi-Fi network for this to work.
Casting your laptop is useful when you want to show a presentation, watch a video on a bigger screen, or share photos with others in the room. The connection is wireless, so you can move around without unplugging cables.
Key Takeaways
- Windows and Mac laptops cast to Chromecast through the Chrome browser using the Cast button in the menu.
- You can cast your entire screen or just a single browser tab, depending on what you need to show.
- Both your laptop and Chromecast device must connect to the same Wi-Fi network before you start.
- Casting stops when you close the Cast connection, and your TV returns to its normal input.
- Some apps like Netflix and YouTube have their own Cast buttons built in, which work faster than screen casting.
Casting from a Windows laptop
Open the Chrome browser on your Windows laptop. In the top-right corner, click the three vertical dots to open the menu. Look for the option labeled "Cast" — it usually appears near the middle of the menu. Click it.
A window will pop up showing available Chromecast devices on your network. Click the name of your Chromecast. You will see options to cast your entire screen or just the current tab. Choose "Cast entire screen" if you want to show everything on your laptop, or "Cast tab" if you only want to share what is open in that browser tab. Once you select, the casting begins when ready.
To stop casting, click the Cast button again and select "Stop casting." Your TV will return to whatever it was showing before.
Casting from a Mac laptop
The process on a Mac is nearly identical to Windows. Open Chrome and click the three dots in the top-right corner. Select "Cast" from the menu. A window appears listing your Chromecast devices. Click your device name, then choose whether to cast your entire screen or just the current tab.
On a Mac, you may also see a "Sources" option that lets you choose which screen to cast if you have multiple displays connected. Select the screen you want to share, then confirm. To end the cast, click the Cast button again and choose "Stop casting."
What to do if your Chromecast does not appear
If you do not see your Chromecast in the list, check that both your laptop and the Chromecast are connected to the same Wi-Fi network. Look at your laptop's Wi-Fi settings and your Chromecast's network settings in the Google Home app. They must be on the same network.
Restart your Chromecast by unplugging it for 10 seconds, then plugging it back in. Wait about 30 seconds for it to fully start up. Then try the Cast button again. If it still does not appear, restart your laptop's Chrome browser completely and try once more.
If your Chromecast is very far from your Wi-Fi router, the connection may be weak. Move the Chromecast closer to the router or move your laptop closer to both. A weak signal can prevent the devices from finding each other.
Casting individual apps instead of your whole screen
Many apps have their own Cast button built in, which works faster and uses less battery than casting your entire screen. Netflix, YouTube, Spotify, and Google Photos all have Cast buttons. Look for a rectangle with a curved line in the corner — that is the standard Cast icon.
Click the Cast icon inside the app, select your Chromecast, and the content plays on your TV. You can then close the app or lock your laptop without interrupting playback. This is more efficient than screen casting because only the video or audio stream goes to your TV, not your entire screen.
Not every app has a Cast button. If you do not see one, you can still cast the entire screen or just the browser tab containing the app.
Common problems and how to fix them
The cast connection keeps dropping. This usually means your Wi-Fi signal is weak. Move your laptop and Chromecast closer to your router. If you have many devices on your network, try disconnecting some temporarily. Restart your router by unplugging it for 30 seconds.
The video is choppy or lags behind the audio. This happens when your Wi-Fi is busy or slow. Close other apps on your laptop that use the internet, like downloads or video calls. If you are casting video, try casting just the browser tab instead of your entire screen — it uses less bandwidth.
Your laptop screen appears but nothing plays. Some websites block casting for copyright reasons. Netflix, for example, will not let you cast from a browser tab — you must use the Netflix app's Cast button instead. Check the website or app to see if it has its own Cast feature.
The Cast button does not appear in Chrome. Make sure you are using an up-to-date version of Chrome. Open Chrome, click the three dots, go to "Help," then "About Google Chrome." It will update automatically if a newer version is available. Restart Chrome after updating.
Casting from Linux laptops
Linux laptops can cast through Chrome the same way Windows and Mac do. Open Chrome, click the three dots, select "Cast," choose your Chromecast, and pick whether to cast your screen or tab. The steps are identical.
Some Linux users also use a tool called Chromium (the open-source version of Chrome) which has the same Cast feature. If you use Chromium instead of Chrome, the process works the same way.
Frequently Asked Questions
Do I need to install anything on my laptop to cast?
No. If you use Chrome, the Cast feature is already built in. You do not need to read or install anything. Just make sure your Chrome browser is up to date by checking the Help menu.
Can I use my laptop while casting?
Yes. If you are casting your entire screen, anything you do on your laptop appears on the TV. If you are casting just a browser tab, you can use other apps on your laptop without them showing on the TV. You can also lock your laptop or close the lid without stopping the cast.
What if my TV does not have a Chromecast device?
You need a Chromecast device plugged into your TV's HDMI port for this to work. Chromecast is a small device you buy separately. Some newer TVs have Chromecast built in, but most do not. Check your TV's manual or look at the HDMI ports to see if you have one.
Does casting use a lot of internet speed?
Casting uses your Wi-Fi network, so it depends on what you are casting. Casting a browser tab or video uses moderate bandwidth. Casting your entire screen uses more. If you have a slow internet connection, casting may be choppy. Closing other apps and moving closer to your router helps.
Can I cast to multiple TVs at the same time?
No. One laptop can only cast to one Chromecast device at a time. If you want to cast to a different TV, stop the current cast and start a new one with the other Chromecast.
