--- Comment #13 from Jani Nikula <jani.nikula at intel.com> ---
So basically you have an external HDMI display in the same all-in-one box.
Looking from the outside, it sure looks embedded, but from the hardware and
driver perspective it's an external display.

It is likely that DDC/CI is used for backlight control. See details in an
otherwise unrelated bug [1].

This is not a bug in our driver.
