Mirror your phone screen to LG TV without Chromecast: what you need to know before starting

If you have an LG TV with webOS and want to see what’s on your phone screen in a larger format, the good news is that you don’t need any external device for this. LG TVs manufactured from 2016 onwards come with built-in support for Miracast and the proprietary LG Screen Share protocol, which allow you to mirror your screen wirelessly directly over Wi-Fi or through a peer-to-peer connection between the two devices.

The process is simpler than it sounds, but it depends on the TV model, the Android or iOS version on your phone, and how your home network is configured. This guide covers the three most common scenarios in Brazil: Android via Miracast, iPhone via AirPlay (on compatible LG TVs), and HDMI cable as a wired alternative. Read the section that matches your case.

Basic requirements: LG TV with webOS 3.0 or higher, Android phone 5.0 or higher (or iPhone with iOS 12 or higher for AirPlay), and active Wi-Fi connection on the TV. For the cable method, you’ll need an adapter compatible with your phone.

What is Miracast and why it’s already in your LG TV

Miracast is a wireless transmission standard created by the Wi-Fi Alliance that works like a virtual HDMI cable through the air. Unlike Chromecast, which requires an app to “cast” content to the TV over the internet, Miracast mirrors everything that appears on your phone screen in real time, including apps that don’t have a cast button.

LG implemented Miracast within a feature called LG Screen Share. In practice, you access the TV menu, activate Screen Share, and your phone sees the TV as a mirroring destination, just like it would see a wireless projector. The latency (the delay between what happens on your phone and what appears on the TV) varies, but is usually acceptable for presentations, photos, and videos. For games with time-sensitive controls, the wired connection is still more reliable.

It’s worth noting that Miracast does not depend on your home Wi-Fi network: it creates a direct connection between the two devices. This means it works even if the router is on the other side of the house, as long as the phone and TV are close enough to see each other via Wi-Fi Direct signal.

How to mirror Android to LG TV via Screen Share

This method works on virtually all modern Android phones, including Samsung (which calls the feature Smart View), Motorola, Xiaomi, and others.

Enabling Screen Share on LG TV

1. Press the Home button on the TV remote.
2. Go to Settings (gear icon) and then All Settings.
3. Navigate to Network and then Screen Share (on some webOS versions the path is Screen Sharing directly in the main menu).
4. Enable the feature. The TV will now appear as available to nearby devices.

Connecting from your Android phone

1. Open Settings on your phone and look for “Transmit”, “Mirror screen”, “Smart View”, or “Screencast” (the name varies by manufacturer).
2. On recent Samsung phones, slide the quick panel (notifications) and tap Smart View.
3. Wait for the LG TV to appear in the list of available devices.
4. Tap the TV name and confirm the connection on both devices if prompted.
5. Your phone screen will appear on the TV in a few seconds.

To stop, simply tap the active mirroring notification on Android and select Disconnect.

How to mirror iPhone to LG TV via AirPlay 2

AirPlay 2 is Apple’s protocol equivalent to Miracast. Unlike Miracast, it uses the local Wi-Fi network to transmit content, so your phone and TV need to be connected to the same router.

LG added native AirPlay 2 support on models from 2019 onwards with webOS 4.5. To find out if your TV is compatible, visit the official LG website or consult your model’s manual. TVs before 2019 usually don’t support AirPlay natively.

Steps for iPhone (iOS 16 or higher)

1. Make sure your iPhone and LG TV are on the same Wi-Fi network.
2. On the TV, go to Settings > Network and confirm that AirPlay is enabled.
3. On your iPhone, swipe to open Control Center and tap Screen Mirroring (rectangle with triangle icon).
4. Select your LG TV name from the list.
5. If prompted, enter the code that appears on the TV screen.

AirPlay on LG supports resolution up to 4K depending on the model and content being transmitted. Apps like Netflix and Apple TV transmit in optimized quality when AirPlay is compatible with the service.

Using HDMI cable: the most stable alternative

If your home Wi-Fi is overloaded or you want zero latency, the cable is the most reliable solution. The principle is simple: you connect your phone to the TV’s HDMI input using an adapter.

• Android with USB-C: use a USB-C to HDMI adapter. Models from brands like Ugreen, Baseus, and Anker are found in Brazil for prices between R$ 60 and R$ 150, depending on the version (if it supports 4K, for example). Check if your phone supports DisplayPort Alt Mode via USB-C, as without this support the adapter won’t work. This should be described in the manufacturer’s technical sheet.
• iPhone: use a Lightning to Digital AV adapter (Apple) or USB-C to HDMI on iPhone 15 and later models. The original Apple adapter costs around R$ 400, but third-party adapters with verified quality cost less.
• Android with Micro-USB: compatibility is more limited. Check if the model supports MHL (Mobile High-Definition Link), a technology that allows video output through the Micro-USB connector.

After connecting, select the correct HDMI input on the TV remote and your phone screen will appear automatically in most cases.

Common issues and how to fix them

The LG TV doesn’t appear in the Android phone list Confirm that Screen Share is active on the TV. If the feature is on but the TV doesn’t appear, turn off your phone’s Wi-Fi, wait 10 seconds, and reconnect. On some Android phones, Miracast mirroring is hidden in Settings > Connections > Wi-Fi Direct or within developer options.

The image freezes or has high delay Miracast is sensitive to radio interference. If there are many Wi-Fi devices on the same 2.4 GHz band, try moving your phone closer to the TV or configure your router to operate on the 5 GHz band, which has less congestion. Thick walls and household appliances also interfere.

iPhone doesn’t find the LG TV via AirPlay Make sure both devices are on the same network and that Bluetooth is enabled on your iPhone (AirPlay uses Bluetooth for initial device discovery, even though transmission occurs over Wi-Fi). Restarting the TV and router usually solves persistent cases.

The image appears rotated or with black bars This happens when your phone’s orientation doesn’t match the TV’s aspect ratio. Lock automatic rotation on your phone and leave it in landscape (horizontal) mode before starting mirroring.

The USB-C to HDMI adapter doesn’t work As mentioned, your phone needs to support DisplayPort Alt Mode. If it doesn’t, the simple adapter won’t transmit video. In this case, consider an adapter with a dedicated chipset, but check specific compatibility with your phone model before buying.

Frequently asked questions about mirroring to LG TV

Do I need internet for Miracast to work?

No. Miracast creates a direct connection between your phone and TV via Wi-Fi Direct, without going through the router or the internet. You can mirror your screen even without cellular signal or an active home internet plan.

Does LG Screen Share work with any Android phone?

It works with the vast majority of Android phones running Android 5.0 or higher and with Miracast support, which includes virtually all models sold since 2015. Some phones from smaller brands may not have Miracast enabled by default; check the manufacturer’s specifications.

Can I mirror with 4K quality without a cable?

Via Miracast, practical quality is around 1080p on most devices, as the standard has bandwidth limitations. Apple’s AirPlay 2 can transmit content in 4K depending on the app and TV model. To guarantee 4K without compression, the HDMI cable is still the only method that delivers this consistently.

Older LG TV without webOS, can it mirror?

LG TVs before webOS (manufactured before 2014, approximately) usually don’t have native Miracast support. In these cases, Chromecast or an HDMI adapter with an external Miracast receiver are viable alternatives. It’s worth checking the specific model’s manual to confirm.

When each method makes sense for you

Screen Share via Miracast is the right choice for those who want convenience without buying anything. It works well for presentations, displaying photos to family, and watching content that doesn’t have a cast button. AirPlay is the natural option for those who live in the Apple ecosystem and have an LG TV from 2019 onwards.

The HDMI cable is for those who won’t compromise on stability: zero connection drops, minimal latency, and image quality without network compression. If you’re setting up a more complete home setup and thinking about other gadgets for your workspace, it’s worth taking a look at the guide to the best notebooks up to 4000 reais to buy in 2026, which can complement this environment well.

In the end, the three methods covered here work at no additional cost in most cases. Chromecast solves many situations, but it’s clearly not essential when the TV and phone already have this support built in.
