LG Screen Share is LG's proprietary mirroring feature that uses Miracast technology. While iPhones do not support Miracast natively, you can use third-party apps to bridge this gap. Screen Share is useful if your LG TV does not support AirPlay 2.
To use Screen Share, open the Screen Share app on your LG TV. On your iPhone, install a compatible mirroring app such as "TV Assist" or "Mirror for LG TV" from the App Store. These apps use Wi-Fi to connect your iPhone to the LG TV and mirror your screen.
1. Open 'Screen Share' on LG TV 2. Launch mirroring app on iPhone 3. Select LG TV from the app's device list 4. Start mirroring This process establishes a connection through the app, allowing you to cast your iPhone screen to the LG TV even without AirPlay support.
How do you cast videos from iPhone apps to LG TV?
Many popular iPhone apps like YouTube, Netflix, and Hulu have built-in casting features that simplify streaming to LG TVs. These apps detect compatible devices on the same network and allow direct streaming without full screen mirroring.
To cast a video, open the app on your iPhone and look for the Cast icon (usually a rectangle with Wi-Fi waves). Tap it and select your LG TV from the list. The video will then play on the TV while your iPhone acts as a remote control.
1. Open video app on iPhone 2. Tap the Cast icon 3. Choose your LG TV 4. Play the video This method is efficient because it streams content directly to the TV, reducing battery usage and allowing multitasking on your iPhone.
