Share my pc screen on LG smart tv

Miracast allows you to cast (transmit) your PC screen directly to the Miracast receiver on the TV.

Do you see the TV listed when you go through the steps below?

I can't get a video to stream to my lg smart tv in full screen , it's playing full screen on the pc no problem

Hi Steve,

To assist you better, I like to know; how exactly you are trying to stream video from your PC to LG Smart TV?

As an initial step, I suggest you to try updating the display adapter on your system.

Follow the below steps:

• Click on the Start button, and type Device Manager on the search bar.
• Open Device Manager, expand Display Adapters.
• Find and double-click Display Adapters from the left panel to update.
• Right-click the device, and click Update.

As you are able to play the video full screen in your PC, then it might be an issue related to LG Smart TV. I suggest you to check for the LG Smart TV manual and check what all settings need to done to play video in full screen.

Kindly reply to us, with the status of your issue. We will be happy to assist you.
