  • Please clarify your question. Are you asking for: 1) a wireless solution; 2) a wireless solution that doesn't include Miracast or WiDi, or 3) any solution? If Option 3, I'd recommend a HDMI cable between computer and TV: pretty much guaranteed to work.

  • You mention that you were able to connect to your LG Smart TV using Windows. How are you doing this? Perhaps that will help us better understand your issue.

  • @richbl Windows 10 has this by default in screen settings for Intel graphics.

From your comments, it sounds like you're using Miracast under Windows, the successor being Miraclecast. I'd recommend downloading and installing the Miraclecast project. The quick procedure would be to:

  • Download the zip file from the release folder
  • In the miraclecast-1.0 folder, run the autogen.sh script
  • Run ./configure
  • Run make
  • Finally, run sudo make install

This should install Miraclecast on your machine.

For a discussion and additional details, see the detailed AskUbuntu thread here.

  • Offhand, I'd guess that you don't have the proper dependencies installed on your machine. I'd recommend that you work with the project developer and community who can help you troubleshoot specific issues directly.

  • For me it is not easy to compile this, I could not make it. But I did find PPA's in Ubuntu, so things worked to install. I think I connected to my TV, but the problem is to send stream to TV, did not find an easy solution for that (if any).

  • Is Miraclecast project still working? I was able to install it, but I don't know how to use it (as there is not interface/extra button)..
