      I have a Dell inspiron 7746, comes with intel HD 5500 integrated graphics and Nvidia 845M. After I had to change my hard drive, I recovered my windows 8 (originally on the laptop) and then reinstalled windows 10 home (build 1079).

      ever since I replaced the hard drive I can bot get the HDMI port to output anything. no external monitor works.  I tried different laptop and the monitors are fine.

      Since then I have updated my BIOS, updated the graphic drivers, uninstalled and reinstalled the drivers. I can't think of anything else. The diagnostics test do not shoe any thing wrong with my laptop. all other ports and internal parts work just fine. I can't tell what could have gone wrong. I am suspicious that this is software related problem but I cant be sure. can anyone help me with this?
