Update on my issue: Mea Culpa! I had previously tried a second cable, with no luck. But lacking other fixes, I scrounged around my house and rounded up 5 cables that I had laying around. Out of the 5 cables, 2 of them work properly! So, 3 of 5 cables do NOT work properly, and 2 of 5 do work. And this is consistent and repetitive results. Go figure.
In the attached photo, the 2 cables at the bottom are the ones that work properly, and the 3 at the top do not work properly.
