How to Stream from a Mac to a TV via Wi-Fi: All the Wireless Methods

Wireless screen sharing with MacBook or iMac Streaming to your TV via Wi-Fi saves time and eliminates the clutter of cables. However, not all users know that for stable streaming, simply turning on AirPlay — it is important to set up the network correctly, choose the optimal protocol and take into account the limitations of specific models Smart TVIn this article, we'll cover all the current methods for displaying images, from standard functions macOS to third-party solutions, and we will also explain why delays or connection interruptions sometimes occur.

The main problem with connecting via Wi-Fi is the quality of broadcasting depends on the network bandwidth and the TV's support for specific protocolsFor example, old models Samsung (before 2018) may not be supported AirPlay 2, and the TVs are on Android TV often require additional applications to work with MacWe tested all methods on devices from 2020 to 2026 and highlighted key nuances that will help avoid common mistakes.

1. Network Preparation: Why It's More Important Than You Think

Before setting up your broadcast, check your Wi-Fi network settings. 80% of your success depends on them!

Many users experience lags or connection drops due to the router operating in an overcrowded range. 2.4 GHz or uses an outdated standard 802.11nTo broadcast video in quality 1080p and above it is recommended:

• 📶 Switch to range 5 GHz (if it is supported by and Mac, and TV). This will reduce interference from neighboring networks.
• 🔄 Enable mode WMM (Wi-Fi Multimedia) in the router settings - it prioritizes multimedia traffic.
• 📡 Set the channel manually (for example, 36 or 149), avoiding automatic selection.
• 🔒 Use encryption WPA3 (or at least WPA2-AES) - obsolete WPA-TKIP slows down data transfer.

Also make sure that Mac and the TV are connected to the same networkIf you have guest Wi-Fi or multiple SSIDs (for example, for 2.4 GHz And 5 GHz separately), the broadcast will not work. To check, open it on Mac terminal and enter:

networksetup -getinfo Wi-Fi

Find the line in the output Router — this IP address must match the gateway address on the TV (checked in the TV network settings).

2. Method 1: AirPlay is the easiest method for the Apple ecosystem

AirPlay - this is a proprietary protocol Apple, which allows you to broadcast your screen Mac on compatible devices, including TVs. It works out of the box on models Samsung (since 2018), LG (since 2019), Sony Bravia (since 2020) and Apple TV all generations.

To start broadcasting:

1. Make sure your TV is in the "On" mode. AirPlay (usually on the menu Settings → General → Apple AirPlay or Network → AirPlay and HomeKit).
2. On Mac open System Preferences → Displays.
3. Click the button Duplicate screen (or Connect as a separate screen) and select your TV from the list.

If your TV does not appear in the list, check:

• 🔌 Are both devices connected to the same Wi-Fi network (see section 1).
• 🔄 Is the firmware updated? Mac and TV (especially relevant for LG WebOS And Samsung Tizen).
• 🛡️ Is the streaming blocked by a firewall or VPN? Mac (turn them off temporarily for testing).

Devices on the same Wi-Fi network

AirPlay is enabled on the TV.

Firmware macOS and TV updated

Firewall/VPN disabled-->

⚠️ Attention: On some TVs Samsung The AirPlay feature may be automatically disabled after a firmware update. Check its status in the menu. Settings → General → External Devices → Apple AirPlay Settings.

If the image is transmitted with a delay, try:

• Reduce screen resolution by Mac (V System Preferences → Displays).
• Disable background apps that consume traffic (eg. Zoom or Steam).
• Connect Mac to the router via cable (if possible), leaving the TV on Wi-Fi.

3. Method 2: Miracast is a universal standard for Windows and Android

Miracast - is a cross-platform wireless broadcasting protocol that is supported by most modern TVs Android TV, LG WebOS And Samsung Tizen. However macOS does not have built-in Miracast support, so third-party software is required.

The most reliable programs for Mac:
