Inspiron 15 7566 - HDMI not working

Got a new Dell "gaming" laptop, Intel + NVIDIA 960M. Everything works mostly out of box, except the HDMI output.
HDMI port not "seen" when cable is connected after boot; but some connection made when cable is already connected at startup/boot.
No HDMI messages in the startup logs (dmesg and journalctl) when cable is not connected.

Anyone have some pointers on how to start debugging the issue?

linux 4.10.1-1
xf86-video-intel 1:2.99.917+760+ge9cd8c21-1
nvidia 378.13-3
xorg-server 1.19.2-1

Regards
M

Got some debug out, adding kernel parameter "drm.debug=0x1e"

Re: Inspiron 15 7566 - HDMI not working

Possibly a step closer.  Seems that some Intel GPUs naturally outputs Displayport, that needs to be adjusted (converted) to HDMI onboard (LSPCON).
See https://patchwork.freedesktop.org/series/8024/
Not sure why this works when connected at boot (maybe the BIOS does something).
Still trying to get the nightly Intel driver (with LSPCON) installed.

[update]
Intel DRM nightly installed (linux-drm-intel-nightly 20160823-1) - no change

Re: Inspiron 15 7566 - HDMI not working

I have a Dell 7566 too but I'm not able to connect a HDMI display, not even when connected early at boot.
I connected a LG display via HDMI port, rebooted and xrandr says only:

Screen 0: minimum 8 x 8, current 1920 x 1080, maximum 16384 x 16384
eDP-1-1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
   1920x1080     60.05*+  48.04  
   1400x1050     59.98  
  <... omitted ...>
   320x240       60.05  
DP-1-1 disconnected (normal left inverted right x axis y axis)

I have nvidia driver. I also tried nouveau driver, output was similar: I had eDP1, DP1 and VIRTUAL1.

Any advice on how to connect HDMI display?

Edit: an interesting fact: When I booted SystemRescueCD Linux (nouveau driver), xrandr outputted also "HDMI1 disconnected" but with no modes listed. I tried forcing 1920x1080 mode (cvt 1920 1080 60, xrandr --newmode... etc.), however it failed with a message like "failed with crtc 1"...

Re: Inspiron 15 7566 - HDMI not working

OK, I partially solved it and my findings might help other with Dell 7566. My problem was two-fold:
1. My HDMI cable was wrong, or not supported... (although, the cable works fine connecting my TV and set-top-box)
2. Hot-plug doesn't work... HDMI must be connected during boot. And even so, when later unplugged and reconnected, the image won't show up, it's like the display won't wake up... However, a little hack helps: suspending and resuming NB with HDMI connected.
