I sent gateway the link to this thread (and another one), concerning this DMI-D cable issue and got this response:
I apologize for the inconvenience this has caused. Based on the
documentation number you have provided, I have learned that there is a process that was made for your unit to be replaced. At this point, I would like to suggest that you have to wait for your replacement Monitor. Meanwhile, please try to use the VGA cable port for you to use your system.
