--- Comment #1 from Jani Nikula <jani.nikula at intel.com> ---
HDMI 1.4a section 6.6 Video Quantization Ranges: Black and white levels for
video components shall be either "Full Range" or "Limited Range." Limited Range
shall be used for all video formats defined in CEA-861-D, with the exception of
VGA (640x480) format, which requires Full Range.

CEA-861-D section 4.15 1920x1080p @ 59.94/60Hz (Format 16).

(CEA-861-D does not define the format at 75 Hz.)
