--- Comment #1 from Gary Wang <gary.c.wang at intel.com> ---
The HDMI port is designed by Thunderbolt interface with following conditions,

Port-B is for HDMI in Alpine Ridge (Integrated DisplayPort with HDMI/DVI
Compatible in VBIOS's VBT).
Port-C is for Type-C in Alpine Ridge (Integrated DisplayPort with HDMI/DVI
Compatible in VBIOS's VBT).
Port-D is disabled.

If "Integrated HDMI/DVI" is used for Port-B, this issue went away.
