Updated graphics card drivers to the latest version on the Dell website. Updated wireless card drivers to latest version. The laptop seems to be able to connect and usually the TV will show the laptop's display for about 5 seconds before the image either freezes or the connection is dropped. Whenever I put my TV in the "screen mirroring" mode, the laptop is able to see the TV when choosing the function to connect to a wireless display. Unfortunately I haven't been able to use it with this laptop since then. The additional bonus would be that an Intel wireless card is no longer required. I looked for the WiDi drivers and found that Intel has discontinued the product saying that Windows now has good Miracast support that can be used instead. I didn't use the functionality for a while and have reinstalled Windows 10 on that laptop since.
I remember having to install an Intel wireless card and the need to install a piece of software called Intel WiDi to make it work.
A good year ago I was able to wirelessly duplicate my laptop's screen to a Samsung UE40J6200 TV. I have a Dell Inspirunning Wind(Fall Creators Update).
