How to Cast to an LG TV: The Ultimate Guide

Casting your phone, tablet, or computer screen to your LG TV is a great way to view content on the big screen. Whether you want to stream a movie, play a game, or share a presentation, casting makes it easy to mirror your device‘s display directly on your TV.

According to a 2022 survey by Statista, over 60% of smart TV owners now regularly use screen mirroring features. With screen casting becoming a mainstream use case, TV manufacturers like LG have built dedicated protocols into their models to support this connectivity.

In this comprehensive guide, we’ll cover the ins and outs of casting to an LG smart TV model, delving into the technical details behind the experience while making concrete recommendations for both new and experienced users. Let’s get started!

An Introduction to Casting

Before jumping into LG specifics, let’s quickly cover some casting basics. Casting refers to wirelessly displaying or “mirroring” your smartphone, tablet, or computer screen onto a TV or other large display. This lets you enjoy content from small devices on the big screen.

There are two main approaches to casting:

Screen mirroring – Mirrors your entire device display to the TV. This shows exactly what’s on your device screen.

Smart casting – Casts specific app content like Netflix. Doesn’t mirror everything.

Under the hood, casting relies on WiFi protocols like Google Cast, Miracast, AirPlay, and DLNA to transmit audio/video from one device to another compatible display. Screen mirroring also typically compresses the video stream to minimize latency.

According to recent data from Display Supply Chain Consultants, more than 50% of today’s smart TVs support screen mirroring without any additional hardware. For TVs that lack built-in casting, external devices like the Chromecast can fill the gap.

What You‘ll Need to Cast to an LG TV

Before you can start casting, you’ll need to make sure you have compatible hardware:

LG TV requirements:

• LG smart TV model 2013 or newer
• Screen mirroring support via protocols like Miracast, WiDi, or AirPlay
• Wired alternative like HDMI or DLNA as a backup

Mobile device requirements:

• Android 5.0+ device with Miracast support for mirroring
• iOS 12+ device with AirPlay support
• Alternate casting apps as needed

Computer requirements:

• Windows 10+ with Miracast support
• macOS 10.14+ with AirPlay support
• Third-party screen mirroring apps as needed

Make sure you update your LG TV firmware and download any required apps to enable casting functions before getting started. Keeping software updated improves connectivity and fixes bugs.

With compatible hardware in place, let’s walk through how to cast from popular devices.

Casting from Android Phones and Tablets

The easiest way to cast from an Android device is using native screen mirroring:

1. Connect your Android device and LG TV to the same WiFi network.
2. Open Quick Settings and tap the Screen Mirroring option.
3. Select your LG TV from the list of available devices.
4. Accept the prompt on your TV and your Android screen will mirror.

This uses either Miracast or DLNA under the hood to stream up to 1080p video and audio. Newer Android devices with Miracast support offer the fastest performance with lowest latency.

If your LG TV isn’t detected, first try restarting your TV and router to refresh the network connection. Also ensure screen sharing is enabled in your TV settings menu under Connections > Screen Share.

For additional functionality, consider using the LG TV Plus mobile app. This allows screen mirroring as well as streaming photos, videos, and music from your Android device to older 2013-2016 LG TV models.

Casting from iPhones and iPads

On Apple devices, you can leverage AirPlay to cast to an LG TV:

1. Enable AirPlay on your LG TV under Settings > AirPlay.
2. Open Control Center on your iOS device and select Screen Mirroring.
3. Choose your LG TV from the list.
4. Accept the connection prompt to begin casting.

AirPlay provides a very fast and stable casting solution with minimal lag. Make sure to check for AirPlay compatibility as some older LG models may need an app like AirScreen to receive AirPlay streams.

One tip is to close and reopen an app if your LG TV isn’t displaying in the AirPlay list. This often triggers device discovery. Restarting your iOS device can also refresh network connectivity if needed.

Casting from Windows PCs

Windows 10 includes built-in wireless projection support for casting your screen:

1. Go to Settings > System > Projecting to this PC and enable wireless projection.
2. Use Win+P to open the Project menu and select Connect to Wireless Display.
3. Choose your LG TV from the list of wireless displays.

This uses either Miracast or WiDi under the hood depending on your hardware. Some older PCs may need an additional program like the Intel WiDi app to cast reliably via WiDi.

If your LG TV isn’t detected, check that screen sharing is enabled in your TV settings under Connections > Screen Share. Restarting both devices can also help establish communication.

As an alternative, the third-party app AirParrot 3 allows casting from Windows 7 and up using simulated AirPlay. This provides wider device compatibility.

Casting from Macs

You can leverage AirPlay to cast your Mac‘s screen to an LG TV:

1. Click the AirPlay icon in your Mac‘s menu bar and select your LG TV.
2. If prompted, enter the AirPlay PIN displayed on your TV screen.
3. Your Mac‘s display will now mirror to the TV.

All modern Macs support AirPlay screen mirroring without any additional software needed. As with iOS, just make sure your LG TV has AirPlay enabled in its settings to appear as an available device.

For older Macs, apps like AirParrot 2 can enable AirPlay compatibility. This lets you cast to TVs that don’t support Apple’s standard AirPlay protocol.

Using a Chromecast Dongle

While LG smart TVs don’t directly integrate Chromecast functionality, you can replicate the experience using an external Chromecast device:

1. Plug the Chromecast dongle into your TV’s HDMI port.
2. Download the Chromecast app on your phone, tablet, or computer.
3. Connect to the Chromecast network during setup.
4. Cast apps by tapping the Cast button in supported apps.

Chromecast relies on your local network to stream video from casting devices rather than native TV protocols. This provides a consistent experience across TV brands.

One benefit of Chromecast is the ability to cast apps like YouTube and Spotify that don’t have native LG TV support. Just note you’ll need an open HDMI port to use a Chromecast.

Using Third-Party Casting Apps

In addition to built-in options, third-party apps allow casting from different devices and protocols:

• Roku – Cast to LG TVs with built-in Roku OS using the mobile app.
• Plex – Stream personal media from a Plex server to your LG TV.
• Miracast receivers – Turn an LG TV into a Miracast endpoint for Android casting.
• AirScreen – Enables AirPlay support on non-Apple TVs like LG models.

These apps work by emulating protocols like Miracast and AirPlay using a local network connection. They add more flexibility for times when native casting options fail or have compatibility issues.

The tradeoff with third-party casting apps is potential instability or lag compared to mature first-party solutions. But the extra functionality is often worth experimenting with to find an optimal setup.
