I am not very sure, looks like somehow during the boot time the DP monitor is
getting a fake EDID from the FW, as the name of the monitor shown is:"ELD
monitor BOBCAT2800". Bobcat is MCA FW's name. Seeing this, I am assuming that
FW is somehow providing a backup EDID, as it's not able to read the EDID
properly from the monitor (which doesn't even exists). 

Lets see if with the latest FW flashing if this issue is gone.
