My daughter ran away with my spare HDMI monitor so I was left with DVI-D. With this adapter I can connect a second monitor to my Mac because the second hole in the Mac is Thunderbolt. This works transparently for Mac, the only setting was to change from "Duplicate Display" to "Continue Display" on Mac. Not sure what thickness and transparency have to do with it, but one end of the adapter smartly connects to the Mac, the other end smartly connects to the DVI-D cable, and it works fine.
