When running in HDMI mode, the monitor expects properly formatted CEA infoframe
packets (for audio, 3D, colorspace, etc.) from the source, however, at the
moment, we don't yet have support for them in the open source driver for
evergreen hw.  The monitor can misinterpret the bogus/missing infoframe packets
and do strange things.
