The Basic Steps to Cast Chrome to Your TV
To cast from Google Chrome to your TV, open Chrome on your computer, click the three-dot menu in the top right corner, select Cast, choose your Chromecast device from the list, and then select what you want to send — either your entire screen or just the Chrome tab you're viewing. Your TV will display whatever you cast within a few seconds. The connection works over your home WiFi network, so both your computer and Chromecast device must be on the same network.
The Cast option appears in Chrome's menu only if you have a Chromecast device set up and powered on. If you don't see it, check that your Chromecast is plugged in, connected to the same WiFi network as your computer, and fully booted up — this usually takes about a minute after you plug it in.
Key Takeaways
- Open Chrome's menu, select Cast, pick your device, and choose whether to send your whole screen or just one tab.
- Your computer and Chromecast must be on the same WiFi network for casting to work.
- Casting the entire screen shows everything on your desktop; casting a tab shows only that browser window and uses less bandwidth.
- You can stop casting by clicking the Cast icon again and selecting Disconnect, or by unplugging the Chromecast device.
Cast Your Entire Screen vs. Cast a Single Tab
Chrome gives you two casting options, and which one you choose depends on what you're doing. Cast entire screen sends everything on your computer monitor to the TV — your desktop, all open windows, and any notifications. This is useful if you're giving a presentation, showing photos from multiple folders, or want to mirror your whole workspace. The downside is that your computer's fan may run harder because it's processing more data.
Cast tab sends only the active Chrome tab to your TV. This is the better choice for watching videos, looking at websites, or streaming content, because it uses less of your computer's processing power and bandwidth. If you switch to a different tab while casting a tab, the TV will go blank until you switch back. If you want to show something else, you'll need to click back to that tab or stop casting and start again with a different one.
What to Do If Cast Doesn't Appear in Your Menu
The Cast option only shows up in Chrome's menu when your Chromecast device is powered on and connected to WiFi. If you don't see it, first check that your Chromecast is plugged into power and into an HDMI port on your TV. Look for a light on the device — it should be solid white or blue when it's ready. If the light is off or red, unplug it, wait 10 seconds, and plug it back in.
Next, make sure your Chromecast and your computer are on the same WiFi network. Open your computer's WiFi settings and confirm you're connected to the same network name (SSID) that your Chromecast is using. You can find your Chromecast's network in the Google Home app on your phone — open it, tap the Chromecast device, tap the gear icon, and look for the WiFi network name under Device Information.
If both devices are on the same network and the Chromecast is powered on, try restarting Chrome. Close the browser completely and open it again. If Cast still doesn't appear, restart your computer and your Chromecast device.
Controlling Playback While Casting
Once you've started casting, a small Cast icon appears in your Chrome address bar. Click it anytime to see playback controls — you can pause, play, adjust volume, or disconnect. The controls that appear depend on what you're casting. If you're casting a video from YouTube or Netflix, you'll see play and pause buttons. If you're casting your entire screen, the controls are more limited because you're mirroring your desktop rather than streaming a specific app.
You can also control casting from your TV remote if your Chromecast supports it, though this varies by device and app. For most video streaming, the remote controls work smoothly. For screen mirroring, remote control is usually not available — you'll need to use your computer keyboard and mouse or trackpad.
Stopping the Cast and Disconnecting
To stop casting, click the Cast icon in your Chrome address bar and select Disconnect. The TV will return to whatever it was showing before you started casting. You can also stop casting by unplugging the Chromecast device, though this is not the cleanest way to end the connection — disconnecting through the menu is better for the device.
If you walk away from your computer while casting, the cast will continue until you manually disconnect it or your computer goes to sleep. Some computers will stop casting when they enter sleep mode; others will keep the connection active. If you want to make sure casting stops when your computer sleeps, disconnect before closing your laptop or letting it idle.
Casting From Different Devices and Browsers
Casting works from any computer running Chrome — Windows, Mac, or Linux. You cannot cast from other browsers like Firefox, Safari, or Edge, because the Cast feature is built into Chrome only. If you want to cast from a different browser, you'll need to open Chrome instead.
If you have multiple Chromecast devices in your home, the Cast menu will show all of them. Click the one you want to use. You can cast to only one device at a time from a single Chrome window, but if you open Chrome on a different computer, that computer can cast to a different Chromecast device simultaneously.
Troubleshooting Common Casting Problems
If your cast keeps dropping or freezing, the most common cause is WiFi interference or a weak signal. Move your Chromecast closer to your router, or move your router closer to where you're sitting. If you have a 5GHz WiFi network available, try connecting your Chromecast to that instead of 2.4GHz — it's faster and less crowded in most homes, though it has shorter range.
If video is choppy or audio is out of sync, close other apps and browser tabs that are using your WiFi. Streaming video, downloads, and video calls on other devices will slow down your cast. If the problem persists, restart your router by unplugging it for 30 seconds, then plugging it back in.
If your TV shows a black screen or "no signal" message, make sure the TV is set to the correct HDMI input. Use your TV remote to switch to the HDMI port where your Chromecast is plugged in. Also check that your Chromecast is fully booted — wait at least one minute after plugging it in before trying to cast.
Frequently Asked Questions
Can I cast from my phone or tablet to the TV using Chrome?
Chrome on Android phones and tablets has a Cast feature, but it works differently than on a computer. You can cast web pages and some apps, but the process is the same: tap the three-dot menu, select Cast, choose your device, and pick what to send. iOS devices (iPhone and iPad) cannot cast through Chrome because Apple restricts this feature.
Do I need to pay for anything to use Chromecast casting?
No. Casting itself is free. You don't pay Google or your internet provider to use the feature. If you're casting video from a paid streaming service like Netflix or Disney+, you'll need a subscription to that service, but that's separate from the casting feature.
What happens to my computer when I'm casting?
Your computer stays in control of what's being cast. If you're casting a tab, you can continue using other tabs and apps on your computer — the cast won't be affected. If you're casting your entire screen, anything you do on your computer will show on the TV, including opening new windows or typing. Your computer must stay powered on and connected to WiFi for the cast to continue.
Can I cast to a TV that doesn't have a Chromecast device?
Not directly through Chrome. You need a Chromecast device plugged into the TV's HDMI port. Some newer TVs have Chromecast built in, so you don't need a separate device — check your TV's manual or settings to see if it has this feature. If your TV doesn't have Chromecast built in and you don't have a separate device, you'll need to purchase one.
Is casting the same as screen mirroring?
They're similar but not identical. Screen mirroring sends an exact copy of your screen to the TV, including your cursor and notifications. Casting can do this, but it can also send just a single app or tab, which uses less bandwidth. When you cast a tab in Chrome, you're not mirroring — you're streaming just that one window.
