How to Mirror Laptop Screen to Samsung/ LG Smart TV Over WiFi

With the evolution of HDMI, it’s possible to connect your laptop to HD TV or any other external display without much hassle. But problem is that it requires the connection to be wired and lengthy HDMI cables are quite costly.In this post, I will show you how to wirelessly mirror Laptop screen to any Smart TV.

Intel’s wireless display technology known as WiDi helps us stream audio and video to external devices. Intel WiDi 3.5 which is Miracast compatible offers direct competition to Apple’s Airplay.

How to Connect Windows 8 laptop to Smart TV using WiDi /Miracast

In this setup, I’m using LG Smart TV with WiFi card attached, Sony Vaio laptop with Windows 8 & D-Link router. Both Laptop and TV is connected to same router.

1. Press Windows key and search for Intel WiDi application.

    After connecting over WiDi from laptop to smart tv, I’m getting black screen in TV and not showing laptop screen. It’s totally showing as blank after accepting connection request from DLNA/ WiDi.

      Make sure you’ve turned ON WiDi in setings on TV.

      Go to Smart TV> User Settings>

      Find the option of Intel Widi/ Miracast and Turn it ON. Then connect your laptop to TV. It will work. I too had faced similar problem of getting blank screen once WiDi is connected.

          Hi Aman,

          Have you tried manually turning on WiDi /Miracast in Smart TV settings?
          Enable Widi in TV and then connect from laptop.
