Transferring images from a smartphone Android to TV opens up a lot of possibilities - from viewing content to presentations. However, not all methods are equally convenient: in some cases you will need to buy an adapter, and in others, built-in functions are sufficient.

If you have previously tried to connect and encountered problems, there is a section at the end of the article with solutions to the most common problems. We will also compare the methods according to three criteria: ease of setup, picture quality and signal delay.

1. Wireless transmission via Wi-Fi (Miracast/Wi-Fi Direct)

Technology Miracast allows you to duplicate your smartphone screen to a TV LG wirelessly, using direct connection via Wi-Fi Direct. This is a built-in feature in most modern devices, but there are nuances:

2. Connection via HDMI (wired method)

If you need maximum quality without delays (for example, for games or video in 4K@60fps), a wired connection via HDMI is the best choice. However, there are two scenarios here depending on the connector of your smartphone:

  • 🔌 USB-C → HDMI: Modern phones (for example, Samsung Galaxy S22, Google Pixel 7) support DisplayPort Alt Mode. You need an adapter USB-C to HDMI (cost from 500 ₽).
  • ⚡ Micro-USB → HDMI: For older models (before 2016) you will need an adapter with support MHL (Mobile High-Definition Link). Make sure that your phone is compatible with MHL!

Step-by-step guide:

  1. Connect the adapter to the smartphone and the HDMI cable to the port HDMI 1/2 on the TV LG.
  2. Press the button on the TV remote control INPUT (or SOURCE) and select the appropriate HDMI port.
  3. On your phone, an option will appear in the notification shade Transfer via HDMI —activate it.
Type adapter Max. resolution Latency Power
USB-C → HDMI (DisplayPort) 4K@60Hz ~10 ms From phone
Micro-USB → HDMI (MHL) 1080p@30Hz ~20 ms Requires external source
USB-C → HDMI (passive) 1080p@60Hz ~15 ms From phone
⚠️ Attention: Adapters MHL may overheat with prolonged use. If the image begins to “scatter,” let the device cool for 10–15 minutes.
💡

Before purchasing an adapter, check whether your phone supports DisplayPort Alt Mode. A list of compatible models can be found on the chipset manufacturer’s website (for example, Qualcomm or MediaTek).
