I understand Clone Mode does not work in newer versions of the graphics driver.
Let me apologize for any inconvenience this issue may be causing to you.
In order to help you better I would like to gather more information about the configuration you have in the computer. Please attach to this thread the .txt file the Intel® System Support Utility will generate https://downloadcenter.intel.com/download/25293/Intel-System-Support-Utility
Does the issue happen only with Clone Mode? Have you tried other Display Modes like Extended Desktop?
What is the behavior of the computer when you try to set Clone Mode?
To attach a file, you must click “Use Advanced Editor” on the upper right hand corner of the response box, then the “attach” option will appear on the bottom right hand corner of the response box.
I have attached the requested txt file.
Both clone mode and extended desktop mode doesn't work. The pc doesn't give any error but the tv failed to connect saying "video data is not supported".
A lot of peoples have the same problem, see microsoft forum threads:
Thanks for the information you sent to me.
I tried to reproduce the issue in our lab with a Dell* XPS laptop we have with hybrid graphics, but dual display worked fine. I tried different versions of the graphics driver, different video ports (HDMI and Displayport*), different operating systems (Windows 8.1* and Windows 10*), but I was not able to reproduce the issue. I also tried Clone Mode and Extended Desktop.
What type of video cable are you using between the computer and the external display?
I attached two screenshots showing the results of the tests.
The problem I am speaking about is wireless screen mirroring via wifi (miracast).
Of course screen mirroring work with a cable, sorry if i wasn't enough describing the problem.
What happens is that support for Miracast* is provided by Microsoft* directly. I recommend contacting them so they can provide more advanced troubleshooting steps with this issue.
If after troubleshooting with Microsoft* issue persists then they might be able to setup a lab in order to find out what is causing the issue. If the issue is related to our driver then Microsoft* should be able to escalate it to us internally.
