LG Aristo 3 Screen Mirroring to Roku / Aristo 3 Plus Cast to TV

We can mirror an Android Smartphone to the big TV screen via wired & wireless Screen Mirroring.

The wired connection can be established using MHL, HDMI, or Slimport Adapter.

The wireless display sharing can be done in 2 ways. We can mirror the Android phone screen to the TV via Screen Mirroring or Screen Casting.

As the name suggests, mirroring creates a mirror image of the phone screen on the TV.

However, Casting lets you do something else on the phone, once you cast a video or image to the TV screen. You can even turn off the phone screen and keep playing the video on the TV screen.

Let’s find out the ways to Mirror an LG Aristo 3 Screen to TV  –

LG Aristo 3 MHL / HDMI Compatibility

Wired screen mirroring can be done using an MHL adapter. It’s one end goes to the phone’s micro USB port and another end to the TV’s HDMI port.

However, the phone should be compatible with MHL / HDMI / Slimport to achieve this. A wired connection offers a more stable connection with less lag, especially during gaming. The best part is that it works without an internet connection.

I failed to find an MHL / HDMI cable that can mirror the Aristo 3 Screen to the TV using a wired connection. Unfortunately, Aristo 3 not compatible with MHL.

In the next step, we are going to try wireless screen mirroring –


LG Aristo 3 Screen Mirroring to Chromecast / Does LG Aristo 3 have Screen Mirroring?


For Screen Mirroring to work, the Phone should be Miracast enabled. We usually get a “Cast” option in Settings which helps us to enable wireless display mirroring.

Unfortunately, I couldn’t find the “Cast” option anywhere on the LG Aristo 3.

So, our only option left is to use Chromecast to enable Screen Mirroring on Aristo 3 & Aristo 3 Plus. Chromecast uses the Google Home app for screen mirroring. Let’s see how to do that –

Connect the Chromecast device to your TV’s HDMI port.

The TV screen says to get the Google Home app for Chromecast setup.

Let’s download the Google Home App via Play Store on our Aristo 3 / Aristo 3 Plus.

“Open” Google home after installation is done.

Tap “Get Started” to begin the setup.

We have to choose a Google account to proceed further. Add an account if needed.

The Location services should be on on your LG Aristo 3. You can pull down the notification bar and turn on “Location”.

Now, it’s searching for nearby Chromecast devices.

A Chromecast device with id 5115 is found.

Hit “Yes” to connect to this Chromecast device.

Now, it says “Connected”.

The Chromecast TV screen shows the “S3N4” code.

The same code is displayed on the phone screen. We are setting up the right Chromecast device. Tap “Yes” to proceed further.

Now, choose your device location. Mine is “Office”.

In this step, we have to choose the Wifi network we are going to use with Chromecast.

Select the wifi network and click next.

The Chromecast is connecting to the selected wifi network.

The next screen also shows “Connecting to Home Wifi”.



We are almost done. Just finish the setup on the Google Home app and start mirroring.

Follow the on-screen prompts to move ahead.


The Chromecast is visible as “Office TV”. Select it for more options.

We can adjust the TV volume from this screen.
