The fastest wireless option depends on what you own
The easiest way to connect your PC to a TV wirelessly is usually through Miracast on Windows, AirPlay on Mac, or a Chromecast or Fire TV device plugged into your TV's HDMI port. Which one works for you depends on whether your TV has built-in wireless casting, what operating system your PC runs, and whether you already own a streaming device. Most modern TVs support at least one of these methods, and most PCs have the software built in — you just need to turn it on and pair them.
Before you start, check that your PC and TV are on the same Wi-Fi network. If they are not connected to the same network, they cannot find each other wirelessly. You will also want to make sure your TV is turned on and set to an input that can receive a wireless signal — usually this is automatic, but some TVs require you to select a specific input first.
Key Takeaways
- Windows PCs use Miracast, which works with most modern TVs and does not require extra hardware if your TV supports it.
- Mac computers use AirPlay, which works with Apple TV devices and some newer Samsung and LG TVs, but not most other brands.
- Chromecast and Fire TV devices plug into any TV's HDMI port and work with both Windows and Mac, making them the most flexible option.
- All wireless methods require your PC and TV to be on the same Wi-Fi network before you can connect.
- Wireless casting works best for video, photos, and web browsing, but may have slight lag if you are playing fast-action games or using demanding software.
Using Miracast on Windows
Miracast is built into Windows 10 and Windows 11, and most TVs made after 2015 support it. To cast your screen, open the Action Center by pressing Windows key + A, then click Connect. Your TV should appear in the list if it is on and supports Miracast. Click your TV's name, and your screen will mirror to it within a few seconds.
If your TV does not appear, make sure both devices are on the same Wi-Fi network and that your TV's Miracast or screen mirroring feature is turned on. The setting is usually in your TV's display or network menu and may be called "Screen Mirroring," "Wireless Display," or "Miracast." If your TV is older and does not support Miracast, you can buy a Miracast adapter — a small device that plugs into your TV's HDMI port and adds wireless casting support.
Once connected, you can choose to mirror your entire screen or extend your display so your TV shows different content than your monitor. To switch between these modes, right-click the Connect notification and select your preference. Miracast works over your local network, so it does not use your internet bandwidth, and the connection is usually stable as long as your PC and TV are in the same room.
Using AirPlay on Mac
If you have a Mac, AirPlay is the equivalent of Miracast, but it only works with Apple TV devices and some newer Samsung and LG TVs. To check if your TV supports AirPlay, look in your TV's settings under "AirPlay and HomeKit" or search your TV's manual for AirPlay compatibility.
To cast from a Mac, click the Control Center icon in the top-right corner of your screen, then click Screen Mirroring. Your compatible TV or Apple TV device will appear in the list. Click it, and your Mac's screen will mirror to your TV. If your TV is not listed, make sure it is on the same Wi-Fi network as your Mac and that AirPlay is enabled in your TV's settings.
If your TV does not support AirPlay, an Apple TV device (which plugs into your TV's HDMI port) will add AirPlay support. Apple TV devices range from about $35 for the basic model to $200 for the high-end version, depending on features and storage.
Using Chromecast or Fire TV devices
Chromecast and Fire TV are the most flexible options because they work with any TV that has an HDMI port, and they work with both Windows and Mac. Both devices plug directly into your TV's HDMI input and connect to your Wi-Fi network. Chromecast costs around $30 to $50, and Fire TV devices range from $25 to $100 depending on the model.
To use Chromecast, download the Google Home app on your PC or Mac, open it, and click the Cast button. Select your Chromecast device from the list, and your screen will mirror to your TV. You can also cast individual apps like YouTube, Netflix, or Chrome tabs without mirroring your entire screen — this is useful if you want to keep your PC screen private while showing content on the TV.
Fire TV works similarly. Download the Alexa app or use the Fire TV remote to set it up, then use the Cast feature in compatible apps or mirror your entire screen through your PC's display settings. Fire TV also integrates with Amazon services like Prime Video and Music, which can be useful if you already use those services.
Comparing wireless methods side by side

| Chromecast | Any TV with HDMI, Windows and Mac | $30–50 | 10–15 minutes |
| Fire TV | Any TV with HDMI, Windows and Mac | $25–100 | 10–15 minutes |
Troubleshooting common connection problems
If your PC and TV are not finding each other, the most common cause is that they are not on the same Wi-Fi network. Check your PC's network settings and your TV's network settings to confirm they are both connected to the same network name. If one is on a 2.4 GHz band and the other is on 5 GHz, they may not see each other — try connecting both to the same band in your router settings.
If your TV supports the wireless method but it is not showing up, restart both devices. Turn off your TV completely, wait 10 seconds, and turn it back on. Do the same with your PC. Then try connecting again. If the connection keeps dropping, move your PC and TV closer together or remove obstacles like walls or metal objects between them — wireless signals weaken over distance and through barriers.
If you see your TV in the list but the connection fails, check that your TV's wireless casting feature is actually turned on. Some TVs have this feature disabled by default or require you to accept a pairing request on the TV itself. Look for a notification on your TV screen asking you to confirm the connection, and press yes or accept if prompted.
When wireless casting may not work well
Wireless casting introduces a small delay — usually less than a second — between what you see on your PC and what appears on your TV. For watching videos or browsing the web, this is not noticeable. For fast-action games or real-time applications like video calls, the lag can be frustrating. If you need zero lag, a wired HDMI cable is still the most reliable option.
Wireless casting also depends on your Wi-Fi signal strength. If your router is far from your TV or PC, or if many other devices are using your network, the connection may stutter or drop. If you experience frequent disconnections, try moving your router closer to your devices, reducing the number of devices on your network, or switching to a wired Ethernet connection for your PC if possible.
Some older PCs or TVs may not support any wireless casting method. If your TV was made before 2015 and does not have a smart TV interface, you will likely need to buy an adapter or streaming device. Similarly, if your PC is very old or runs an outdated version of Windows, it may not have Miracast support — check your Windows version and update if needed.
Frequently Asked Questions
Do I need to buy anything to connect wirelessly?
Not if your TV was made after 2015 and your PC is Windows 10 or newer, or a Mac with AirPlay support. Most modern TVs have Miracast or AirPlay built in. If your TV is older or does not support wireless casting, you can buy a Chromecast ($30–50), Fire TV ($25–100), or a Miracast adapter ($20–40) to add wireless support.
Can I use wireless casting to play games?
Yes, but there will be a slight delay between your PC and the TV, usually less than a second. For casual games or turn-based games, this is fine. For fast-action games like shooters or racing games, the lag may affect your performance. Wired HDMI is better for competitive gaming.
Will wireless casting work if my PC and TV are on different Wi-Fi networks?
No. Both devices must be connected to the same Wi-Fi network to communicate wirelessly. If your TV is on a guest network and your PC is on the main network, they will not find each other. Connect both to the same network before attempting to cast.
What if my TV does not have Wi-Fi?
If your TV does not have built-in Wi-Fi, you can plug a Chromecast, Fire TV, or Miracast adapter into its HDMI port. These devices have their own Wi-Fi radios and will connect to your network independently, adding wireless casting to any TV.
Can I cast audio only without showing my screen?
Yes. With Chromecast and Fire TV, you can cast individual apps like Spotify or YouTube Music without mirroring your entire screen. With Miracast and AirPlay, you are mirroring your whole screen, so anything on your PC will show on the TV. If you want audio-only casting, use a Bluetooth speaker or a smart speaker like an Echo or Google Home instead.
