I've been using a Mini DisplayPort to HDMI adapter to connect to an external monitor for over a year. It stopped working yesterday and I am about to replace it. However, I noticed there are Mini DisplayPort to HDMI cables on Amazon, as well. The cable's length, either 3 or 6 feet, may be useful to me. That said, I have 2 HDMI cables already, so getting another cable may just be a waste of space (pricing is roughly the same, as far as I can tell).
So, what difference, if any, is there between the Mini DisplayPort to HDMI adapter vs. the Mini DisplayPort to HDMI cable? Thank you.
