Query: Worked once with each adapter tried, then quit

Hellish. Would work once with each adapter I tried, then quit. Because it worked fine on a friend's laptop I assumed it was the adapters (mini display port to HDMI) that were failing or that I had some kind of software bug. Excruciating weeks were spent ordering new adapters off amazon and searching for software bugs until I realized it was this chthonic HDMI cord. Would not buy again.
