--- Comment #29 from Jani Nikula <jani.nikula at intel.com> ---
Look, the users just vastly outnumber us developers. For some perspective, I
seem to have received 67 bugzilla comments per day, on the average, for the
past 30 days, including weekends. Responding here is just a tiny part of what I
do.

No, I mean the marketing material for your motherboard says you have HDMI 2.0
hardware while your GPU doesn't have it, ergo you have a converter.

Core DRM and i915.

Please provide dmesg for the case where you have HDMI on the port that xrandr
says is DP.

Manasi, have you received the motherboard?
