Windows 10: Cannot mirror computer screen on TV

I use HDMI to mirror computer screen. I plugged the cable in the port and, as a default, it connected as an Extended screen. I pressed Win+P and selected Duplicate but nothing has changed

Mirroring my computer to TV has stopped since November upgrade

I recently upgraded to Wondows 10 Build 1511. As a result, I am unable to mirror my computer screen to my Samsung TV. The TV still shows up under my list of devices in the "Connect" tab of the notifications panel, but when I try to connect it, it immediately
disconnects. Now it seems it has dropped off the list of available devices. Any suggestions on how to get this working again?

 

How to screen mirror my mobile to a TV

I am using lumia 640XL upgraded to windows 10 and HP laptop upgraded from windows 7 to 10.

I was about to screen mirror my mobile to a tv when it was with windows 8.1, but after upgrading i am unable to screen mirror. The tv name is seen on display list and connected even, but screen is not projected on tv. It is getting disconnected.

In the case of laptop also i am able to see the available devices (tv) and connect but after connection established immediately it is getting disconnected.

Screen Mirroring on Win 10 to Samsung Smart Tv

Recently, I have been trying to mirror my computer screen to my Samsung Smart TV. My computer finds the device in the Connect Menu of the Notifications Tab, I've previously not seen the TV listed before, so I tried connecting them with both devices on
and running. My computer connects, formatting the screen and my TV also recognizes the connection, but both after loading for several moments, suddenly disconnect without showing a glimpse of my computer on my TV screen. I have tried repeating this multiple
times, to no avail. My TV then tells me screen mirroring has ended. My TV is updated to the newest update-so that wouldn't be the issue.
