--- Comment #2 from Imre Deak <imre.deak at intel.com> ---
I assume you connect the HDMI display via the DDI0 HDMI plug. In that case it's
expected that HDMI won't work if it's not connected when booting, since the
driver is missing LSPCON support. If the display is connected BIOS will
configure LSPCON.

An HDMI display connected to the DDI1 DP++ port via a type 1 HDMI dongle should
work fine.
