HDMI stopped working after upgrade to Win10

Hi all,

after the upgrade to Win10, HDMI port of my laptop (ASUS ZENBOOK UX21E) stopped working.

When connecting it to my smart TV, HDMI is detected but the screen remain black :/

I tried to download drivers from asus website (https://www.asus.com/supportonly/ux21e/H...) but nothing changed.

Do someone has some advices for me to solve this issue?

Thanks

Leo
