Having 2 different OSes both fail to see the HDMI output sounds like a 
problem that isn't software to me, but read on.

According to the internet, the laptop has one of those 
dual-graphics-card chipsets in it.  (Intel HD Graphic 530 and GeForce 
960M.)  I don't know which card is responsible for handling the HDMI 
port.  According to https://nouveau.freedesktop.org/wiki/FeatureMatrix/ 
, the 960M is in the NV110 class of hardware and so should be able to do 
HDMI with the nouveau X module.  However, the nouveau FAQ says, "If you 
have a laptop with dual Intel/Nvidia graphics, the Nvidia card may or 
may not be usable. The card may be selectable via vgaswitcheroo or a 
BIOS option, you should check those first."

So:  See where the HDMI port is with lspci, maybe see what you can find 
in the BIOS Setup, and investigate the "vgaswitcheroo" program?
