User question:

I would like to think I am good w/technology but cannot figure out how to stream some home videos on my Macbook Pro to my LG OLED. I have an Amazon Firestick and just can't figure out what I need to do. I've done it in the past using Chromecast and VLC but I don't have Chromecast right now. What are my options? — from Reddit

AirPlay Mac to LG TV

AirPlay or AirPlay 2 is Apple’s proprietary technology which you can use to stream videos directly from your Mac to your TV without HDMI or any third-party app.

Not all LG TVs come with built-in AirPlay 2 functionality, though. In fact, devices like Roku and Fire TV also have a limited number of models that support the technology.

Mac Users Attention:

LG Smart TVs have this technology built-in to them, and depending on what model you have, you can mirror videos in ultra HD wirelessly. All you have to do is download a software called LG Smart Share on your PC.

This software allows you to connect multiple devices using DLNA (SmartShare PC, Nero, Plex, SmartShare Mobile, and Elmedia Player), screen share (Miracast/Intel WiDi), and Wi-Fi Direct.

How to Connect Mac to LG TV with HDMI

1. First, connect an HDMI cable to your Mac. If your computer only has Thunderbolt ports, then you’ll have to get an adapter/dongle.

2. Connect the other end of the HDMI cable to your LG TV.

3. Now on your Mac, open System Settings (or System Preferences if you’re on an older version of macOS).

4. Go to Displays and arrange the screens as you like.
