> If you’ve ever tried to plug one of those into the back of a TV, you’ll know it’s still pretty difficult to get it the right way up.

That's true, but the difficulty in that case comes from being unable to see the hole or fit into the space between the television and the wall.

For example, plugging an HDMI cable into the back of a monitor involves none of the difficulty of plugging an HDMI cable into the back of a TV, even though the connector and the port are the same in both cases.
