Hi Tom Xiao,

Intel Wireless Display (WIDI) Technology is a technology that allows you to display content from your notebook PC onto a TV at HD resolutions without having a cable connected from the TV to the Notebook. There are some basic requirements in order to achieve this which are listed in the link below.

Please let me know if this helps.

That link you suggest has been removed so there is no answer to the question.

Here is what I get on my XPS 8700, not sure what it means. hen I try to connect to a Samsung smart TV I can see that it tries and says 'connecting", but then it fails to connect and drops right away.

I inserted the picture below in the previous post, but when I actually posted it it disappeared.

Any rules about adding pictures ?

Pictures with PE dropper Malware are not allowed. complex infection processes, going beyond the traditional phishing and using techniques where the malicious payload is hidden in image files even using a known file format.

Dell doesn't support Samsung TV's
Check the firmware on the Wireless Display/Miracast receiver.  This is not supported by Dell.

Most receivers (including those built into TV's and displays) need updated firmware that specifically includes support for Windows 10

Note: Some older Intel Wireless adapters are not supported under Windows 10.  These adapters may have worked under earlier Windows versions but will not work under Windows 10:

Intel Centrino® Wireless-N 1000,1030
Intel Centrino® Advanced-N 6200, 6230

2nd Generation processor support:
Intel WiDi technology requires a set of compatible hardware, drivers, and software to work properly. This includes, but is not limited to, wireless and graphics drivers for specific platforms for each supported operating system. Many of the features in Windows 10 will not function correctly on older platforms due to driver limitations. As result, systems with 2nd Generation Intel® Core™ processors will not support Intel WiDi (or Miracast) under Windows 10.
