How to Use Chromecast to LG TV [2025 Guide] | Setup & Tips

Chromecast is one of the easiest ways to stream your favorite apps, shows, and videos from your phone or laptop to your TV. If you own an LG TV, you might be wondering — can I use Chromecast with it? And if yes, how do I set it up? The good news: you can absolutely use Chromecast to LG TV, whether it’s a newer model with built-in casting or an older one that needs an external Chromecast device.

This detailed guide walks you through everything you need to know — from setup and compatibility to casting tips, troubleshooting, and advanced streaming tricks.

1. Understanding Chromecast and LG TV Compatibility

Before jumping into the setup, it’s important to know how Chromecast works and whether your LG TV supports it.

What Is Chromecast?

Chromecast is a streaming device developed by Google that allows you to wirelessly send (or “cast”) content from your phone, tablet, or laptop to your TV. It plugs into your TV’s HDMI port and connects to your Wi-Fi.

Do LG TVs Have Built-In Chromecast?

Some newer LG Smart TVs (especially 2021 models and later) have built-in Chromecast, meaning you can cast directly from your device without any extra hardware. These models often run webOS 22 or newer and support both Google Cast and Apple AirPlay 2.

If your TV doesn’t have built-in Chromecast, you can still use an external Chromecast dongle (like Chromecast with Google TV) — it works perfectly with any LG TV that has an HDMI port.

Types of Chromecast Compatible with LG TVs

• Chromecast (1st, 2nd, 3rd Gen) – basic casting from phone or computer.

• Chromecast Ultra – supports 4K and HDR.

• Chromecast with Google TV – has its own operating system and remote, turning your LG TV into a smart TV.

• Built-in Chromecast – available on newer LG models.
