How to connect to an LG TV via Wi-Fi from an iPhone: all the methods and nuances

Wireless connection iPhone to LG TV via Wi-Fi opens up a lot of possibilities: from broadcasting video with YouTube to the big screen to display high-resolution photos. However, many users encounter difficulties—either the TV isn't visible in the device list, or there are delays during streaming. In this article, we'll look into all current connection methods (including Screen Mirroring, AirPlay 2 And LG Smart Share), as well as typical errors and their solutions.

It is important to understand that the connection method depends on LG TV models and versions iOS on yours iPhoneModern TVs with webOS 4.0+ support AirPlay 2 "Out of the box," while older models may require additional apps. We'll cover each scenario in detail so you can choose the best option without unnecessary experimentation.

If you have previously tried to connect and encountered an error like "Unable to connect to LG TV" or "The device is not supported"Don't rush to blame the technology—in 80% of cases, the problem can be solved by configuring the network or updating the firmware. Below you'll find step-by-step instructions with illustrations (in text format) and a compatibility table of LG models with different broadcast protocols.

1. Preparation: Checking compatibility and requirements

Before you begin connecting, make sure your devices meet the minimum requirements. This will save you time and avoid frustration.

LG TV requirements:

• 📺 Models with webOS 4.0 and later (released after 2018) support AirPlay 2 And Screen Mirroring without additional applications.
• 🔄 TVs on webOS 3.0–3.5 (2016–2017) may require installation of an app LG TV Plus or Smart Share.
• 🚫 Outdated models with NetCast or webOS 1.0–2.0 (before 2016) do not support wireless broadcasting with iPhone directly - will be required intermediate device (For example, Apple TV or Chromecast).

iPhone requirements:

• 📱 iOS 12.3+ For AirPlay 2 (recommended) iOS 15+ for stable operation).
• 🔋 Battery charge not lower than 30% - when the battery level is low iOS may block the broadcast.

• 🔄 If the signal is weak, try 2.4 GHz, but expect possible lags.

2. Router settings

• 🎯 Turn on QoS (Quality of Service) in the router settings and set the maximum priority for devices Apple.
• 🔄 Turn off the "Energy saving" (if any) - it can reduce the speed of Wi-Fi.
• 🔒 Use encryption WPA2-AES or WPA3 - outdated standards (WEP, TKIP) slow down the network.

3. Router placement

• 📡 Place the router in an open area, away from metal objects and household appliances.
• 🔌 If the TV and router are in different rooms, use Mesh system or Wi-Fi repeater.
