Apple ecosystem users often face a dilemma: how to display images from a laptop on a large screen if they have a smart TV in the living room but don't have an Apple TV set-top box. Fortunately, modern technology makes it easy. broadcast content Wirelessly, using built-in protocols and third-party solutions. You don't need to buy additional equipment if your TV supports Smart TV.
The main connection method is based on technology AirPlay 2, which has become the standard for many TV manufacturers in recent years. However, there are alternative methods, such as using DLNA servers or installing specialized receiver apps directly on the TV. The specific method you choose depends on your TV model and operating system version. macOS.
In this article, we'll take a detailed look at all available options, assess their pros and cons, and provide step-by-step setup instructions. You'll learn how to control your computer screen from the comfort of your couch and enjoy high-definition content without the hassle of wires.
Checking compatibility and preparing the network
Before you begin setup, you need to make sure your equipment is ready for operation. A fundamental requirement for stable video streaming is the availability of a single Wi-Fi networksBoth devices—the laptop and the TV—must be connected to the same router.
If your TV was released after 2018, there's a good chance it already has built-in AirPlay 2 support. This includes models from Samsung, LG, Sony, Vizio, and Roku TV. Older or lower-end models may require installing a third-party app from the TV's app store.
⚠️ Important: Make sure "Guest Network" is disabled on your router for both devices. Routers often isolate guest networks, which can prevent your MacBook from seeing the TV in the list of available devices.
It's also worth checking that your software is up to date. On your MacBook, go to System Settings → General → Software Updateto ensure you have the latest version of macOS. Similarly, we recommend updating your TV's firmware through the support menu.
Using built-in AirPlay on Smart TV
This is the easiest and highest-quality method, requiring no additional software. If your TV supports AirPlay 2, the setup process takes just minutes. This technology ensures minimal latency and high picture quality.
To activate the feature on your TV, you need to go to the settings. On Samsung models, this is the path Settings → General → Apple AirPlay SettingsOn LG you need to open the menu Home Dashboard → AirPlay & HomeKit SettingsMake sure the switch is in the "On" position.
After activation, a confirmation code may appear on the TV screen. When connecting for the first time, enter this code on your MacBook. Subsequently, the devices will connect automatically when on the same network.
To start casting on a MacBook, click the "Control Center" icon in the menu bar (the two vertical sliders) and select "Mirror Screen." Select your TV from the list. Your desktop image or video will instantly appear on the big screen.
Broadcasting via third-party receiver applications
If built-in AirPlay support isn't available, emulator apps can help. They turn your TV into a signal receiver that understands the Apple protocol. These programs are often called "receivers."
The most popular solutions are AirScreen (for Android TV), Receiver for AirPlay or AirPinThey can be found in official app stores (Google Play Store, LG Content Store, Samsung Apps). Once installed, the app creates a virtual device that your MacBook can see.
The algorithm of actions is as follows:
- 📺 Find and install a receiver app (such as AirScreen) on your TV through its app store.
- 📡 Launch the app on your TV and wait for the "Ready to connect" message or the device name to appear.
- 💻 On your MacBook, open Control Center and click Screen Mirroring.
- 🔗 Select the device name that appears in the running app on your TV.
⚠️ Please note: Free versions of receiver apps often contain ads or have session time limits. For a seamless, uninterrupted experience, you may need to purchase an in-app subscription on your TV.
Streaming quality via third-party apps may be slightly inferior to native AirPlay, especially when playing 4K video. However, for viewing photos, presentations, or YouTube, this method is an excellent solution.
Comparison of connection methods: characteristics table
To help you choose the best option, we've prepared a comparison table of the key characteristics of different streaming methods. Please note latency and the need for additional software.
| Method | The need for software on TV | Latency | Quality | Compatibility |
|---|---|---|---|---|
| Native AirPlay 2 | Not required | Low | High (up to 4K HDR) | New Smart TVs (2018+) |
| Applications (AirScreen) | Installation required | Average | Good (depending on network) | Android TV, older Smart TVs |
| HDMI cable | Not required | Absent | Maximum | Any TV with HDMI |
| DLNA (video only) | A player is required | N/A (file) | High | Almost all Smart TVs |
As the table shows, native AirPlay wins across the board if your equipment supports it. However, the availability of alternatives allows you to use older, yet functional, TVs.
Setting up display and screen resolution
After successfully connecting, it's important to configure the image output settings correctly. It's common for the picture on the TV to be out of proportion with the MacBook screen, appearing stretched or cropped.
To make corrections, go to System Preferences → DisplaysHere you will see two windows: the built-in laptop display and the external one (TV). Select the TV and adjust the resolution. It is recommended to select the mode "Primary display"** if you want to work only with the big screen, or "Extend" to use the TV as a second monitor.
☑️ Checking the broadcast quality
If text on your TV appears blurry, try changing the refresh rate. The default value is 60 Hz, but some TVs may support 50 Hz or 30 Hz at high resolution, which can cause the cursor to feel lagging.
What to do if there is no sound on the TV?
If you see a picture and hear sound from your MacBook speakers, click the speaker icon in the menu bar. Select your TV or Apple TV from the list of output devices. If the device isn't listed, try restarting both devices.
Wi-Fi Troubleshooting and Optimization
Wireless HD video streaming requires a stable connection. If you experience buffering, image tearing, or connection drops, the problem lies with your Wi-Fi network.
Modern routers operate in two bands: 2.4 GHz and 5 GHz. For streaming video from a MacBook, using the appropriate band is critical. 5 GHzIt provides much higher bandwidth for video streaming and is less susceptible to interference from neighboring networks and Bluetooth devices.
Check what frequency your MacBook is running on. Hold down the key Option and click the Wi-Fi icon in the menu bar. The "Channel" line should show a value in the 5 GHz range (usually channels above 100). If you're in a 2.4 GHz zone, move closer to the router or reconfigure it.
⚠️ Note: Router and TV interfaces are constantly being updated. Menu item names may vary depending on the firmware version. If you don't find an exact match, look for similar sections in the network or connection settings.
Frequently Asked Questions (FAQ)
Is it possible to broadcast audio separately, without video?
Yes, you can use your MacBook as an audio source for a home audio system or soundbar connected to your TV. To do this, select the TV as the output device in the sound control menu (the speaker icon). Video can remain on the laptop screen.
Why does my AirPlay streaming keep dropping out every few minutes?
This is most often due to an unstable Wi-Fi signal or channel congestion. Try rebooting your router, turning off other devices consuming bandwidth (torrents, downloads), or moving the router closer to the TV. The router's power-saving mode could also be the cause.
Does this method work if I have an older TV without Smart TV?
Without a Smart TV, you can't connect your MacBook directly via Wi-Fi, as the TV doesn't have an operating system to receive the signal. In this case, you'll need to either purchase a TV box (such as an Android TV box) or use an HDMI cable.
Is there any lag when playing games via AirPlay?
Yes, there is input lag and it can be 100 ms or more. This isn't a big deal for turn-based strategy games or watching movies, but a wireless connection isn't suitable for fast-paced shooters or fighting games. In such cases, use an HDMI cable.
