HDMI not working

Question

After the last Windows 10 Update my HDMI port do not send any signal to my TV or Monitor. I tried to use the HDMI->VGA adapter and works well. I booted the pc with a ubuntu SO (without installation) and HDMI work as well, so, my problem is with the drivers, but i already tried to install all drivers versions available on Dell's driver page and already used many auto detect tools, but no one works. Finally, I installed the last W10 release in a clean installation and the issue remains. Can someone help me?

You tried pressing windows logo key and P key at the same time to open the Connect To A Wireless Display screen? if no, then do so and select Extend in the screen.
