--- Comment #12 from Ricardo Madrigal <ricardox.madrigal.maldonado at intel.com> ---
Analyzing the hardware specifications of "DisplayPort to Dual DisplayPort
Graphics Splitter DPD2001 SUNIX" MST. We have identified that DP 1.2 does not
support enough bandwidth over a single link to drive two 4k monitors, and this
should not be a mistake anymore.
