Modern technology allows you to completely eliminate unnecessary wires, turning your living room into a multimedia hub. If you own Apple devices and an LG TV, you have the perfect opportunity to stream content directly from your laptop to the big screen. This is especially convenient for watching movies, presentations, or high-resolution photos.
The main tool for achieving this task is technology AirPlay 2, which is built into many modern Smart TV models. However, if your TV doesn't support Apple's native protocol, there are effective alternative solutions. In this article, we'll cover all possible wireless connection methods.
Before you begin setup, make sure both devices are on the same network. This critically important condition to enable devices to discover each other. If your router broadcasts signals on both 2.4 GHz and 5 GHz frequencies, make sure both your MacBook and TV are connected to one of them, although modern routers often combine them into a single network.
Checking compatibility and preparing equipment
The first step is to determine your TV's technical capabilities. AirPlay 2 support is available on LG models released in 2018 and later, as well as on some earlier models with a firmware update. This feature is typically found on OLED, NanoCell, and Super UHD TVs.
To check the software version of your LG TV, go to the settings menu. You will need the remote control. Magic Remote For quick navigation, click the gear button, then select All settings, go to the section General and find the item Information about the TV.
- 📺 Make sure your TV model is an OLED, NanoCell, or UHD TV from 2018 or later.
- 📡 Make sure your router supports Wi-Fi 802.11ac or later for stable video transmission.
- 💻 Make sure your MacBook is running macOS Mojave or later.
If your TV model is older than 2018, it may not have built-in AirPlay support. In this case, don't despair, as there are third-party apps that emulate this protocol. However, for the best quality and minimal latency, it's best to use native support.
Setting up AirPlay 2 on an LG TV
If your TV supports Apple technology, you need to activate the corresponding module in webOS. This feature may be disabled by default for security or energy saving reasons. The activation process takes less than a minute.
Using your remote, go to the main menu and find the tile Apple AirPlayIf you don't see it on your home screen, go to Settings, select Connection and find the item Apple AirPlay and HomeKitHere you need to move the switch to the position On.
⚠️ Attention: After enabling AirPlay, your TV may prompt you to update its software. Don't ignore this prompt, as older firmware versions may contain bugs that prevent a stable connection with Apple devices.
You can also configure security settings in the AirPlay settings menu. You can choose whether to require a code each time a new device is connected, or to only allow previously used devices to connect. For home use, it's convenient to set this mode No code required or First time.
☑️ Setting up AirPlay on TV
Connecting a MacBook to a TV via AirPlay
After preparing the TV, we move on to setting up the laptop. Make sure Wi-Fi is enabled on your MacBook and the same network is selected as the one on the TV. In the top menu bar of macOS, find the icon Control center (two horizontal stripes) or icon AirPlay (rectangle with triangle).
When you click the AirPlay icon, the system will search for available devices. Your LG TV should appear in the list. If you see it, simply click its name. The image from your MacBook screen will instantly appear on the TV.
You can choose the broadcast mode. Two main options are available: Screen mirroring, when the contents of the monitor are completely copied to the TV, and Desktop extensionWhen your TV becomes a second monitor, click the AirPlay icon and select the appropriate option to select the mode.
- 🖥️ To watch videos, select the mode where the TV acts as a separate display so you can work on your laptop at the same time.
- 🎮 For games or presentations, use mirroring mode to see what your audience sees.
- 🔊 Check your audio settings: In the AirPlay menu, you can choose where to play audio—on your MacBook speakers or your TV.
If the image appears but you are not satisfied with the quality, check the resolution. Go to System Preferences -> DisplaysHere you can select the optimal resolution and refresh rate to ensure clear and smooth images.
Using third-party apps for older models
Owners of LG TVs released before 2018, or models without built-in AirPlay, can use third-party solutions. The most popular and stable app for the webOS platform is AirBeamTV or TV AssistThese programs are installed directly on the TV through the LG Content Store.
The installation process is simple: open the app store on your TV, search for the app name (e.g., "AirPlay"), and install it. Once launched, the app will create a virtual device that your MacBook will see as a standard AirPlay receiver.
| Application | Installation type | Latency (ms) | 4K support |
|---|---|---|---|
| AirBeamTV | LG Content Store | Low | Yes |
| WebOS AirPlay | LG Content Store | Average | No |
| TV Assist | LG Content Store | Low | Yes |
It's worth keeping in mind that third-party apps may be paid or contain ads. They also place additional strain on the TV's processor, which can lead to micro-lags when playing fast-paced content.
Why can third-party applications slow down?
Third-party apps run in an emulated environment or use less optimized codecs compared to native AirPlay 2. This requires more computing power from the TV's processor, which can cause FPS drops or audio desync.
Alternative methods of streaming via browser
If installing apps isn't possible, you can use the Google Chrome browser on your MacBook. This method is universal and works on virtually any Smart TV that supports Chromecast technology or has a built-in browser. It's a great solution for quickly sharing tabs.
Open your Chrome browser, click on the three dots in the upper right corner and select Broadcast (Cast). In the window that appears, select your LG TV. You can cast either a specific tab or your entire desktop screen.
⚠️ Attention: When streaming through a browser, image quality may be lower than with native AirPlay, and input lag may be higher. This method is not suitable for gaming, but is ideal for displaying web pages or videos from online cinemas.
Many modern LG TVs also have a built-in browser that lets you access video hosting sites (such as YouTube) and play videos there, using your MacBook as a remote control. To do this, click the cast icon on the video in your laptop's browser and select TV.
Troubleshooting connection issues
Even with proper setup, issues may still occur. Most often, the problem lies in network settings or a firewall. If your MacBook doesn't detect your TV, try rebooting your router, as the DNS or DHCP cache may be preventing devices from being discovered on the local network.
Check your firewall settings on macOS. Sometimes the security system blocks incoming connections for the AirPlay service. Go to System Preferences -> Protection and security -> Firewall and make sure that for AirPlay Receiver Incoming traffic is allowed.
- 🔄 Perform a full reboot of the TV by disconnecting it from the network for 30 seconds (cold start).
- 📶 Make sure that AP client isolation (Client Isolation), which prevents devices from seeing each other, is disabled on your router.
- 🔌 If your Wi-Fi signal is weak, try using Wi-Fi Direct if this option is available in your TV menu.
In rare cases, resetting the TV's network settings to factory defaults can help. This will delete all saved Wi-Fi passwords, but it often resolves issues with network modules not working properly.
Frequently Asked Questions (FAQ)
Why is there a delay in image display when connected via WiFi?
Lag is usually caused by a congested wireless channel or a slow router. Try switching to a 5 GHz network if your router and devices support it. Background downloads on other devices on the network can also cause lag.
Is it possible to connect a MacBook to an LG TV without WiFi?
Without a WiFi network (router), you can only connect via Wi-Fi Direct (if supported by both devices) or a wired HDMI connection. Wireless data transfer requires at least a local network connection between the devices.
Does AirPlay stream audio to my LG TV?
Yes, audio is transmitted along with the video stream. However, if you use third-party AirPlay emulation apps on older TVs, audio may be delayed or not transmitted at all. Always check the selected audio output device in the AirPlay settings on your Mac.
How do I disable the code request every time I connect?
Go to AirPlay settings on your LG TV (Settings -> Connection -> Apple AirPlay). Find the parameter Require code and change it to First time or Never (not recommended for public places).
