    the last things to try, if you didn't alread tried:

     

    Uninstall Intel drivers and check if HDMI playback is still here and check if it works

    Uninstall nvidia drivers and check if HDMI playback is still here and check if it works

     

    it must some drivers issue but without the notebook in hands, it's very difficult to narrow the issue.

    please report the correct model number, E?-571G and installed OS.

     

    if HDMI out is used by nVdia card, you can do a quick check on windows services:

    windows key logo + r

    type

    services.msc

    check if NVIDIA Display Driver Service is started (double click on it), if not start it manually and set it to automati start

    then check again if HDMI is still greyed

    The model is E5-571G,with NVIDIA 840M and Windows 7 64 bit

    I check,NVIDIA Display Driver Service and the other services from NVIDIA is on AUTOMATIC!

    have you re-installed both Intel and nvidia VGA drivers?

     

    when you connect to the TV, if you go to the nVidia control panel, are you able to see the TV connected?

    Sorry about questions, but i'm trying to find out what's wrong.

     

    Did you install standard drivers or broadwell drivers?

    It seems that after several installations in different order,now HDMI works!
