After a few days to a week of normal use of my MacBook Pro (Retina, 13-inch, Early 2015 with Intel Iris Graphics 6100 1536 MB) and the BenQ GW2765HT LED monitor via display port, I found that my mac was no longer being detected by my monitor and vice versa. I had no idea what to think except that the wire I had was faulty, so I exchanged it for one of the same brand. And then, bam, another week or so into use of the new wire the same thing happened. This time I decided to exchange it for another brand of Mini Displayport to Displayport cable. The same thing again! Clearly I was not taking the right approach to this problem.
My usual “setup/workflow” is that I have my monitor closed and use only the external display. At night, I turn off the monitor and unplug the power to my MBP (to not overcharge my battery) in no particular order. I wonder if my pulling the power, or some combinations of actions is killing the cable? Any thoughts?
[This was my original thinking, but I have just gotten the cable working again—will offer a preliminary solution below.]
