Display connections are evolving to keep up with new video technology and data rates. See what lies ahead for the future.

Chances are, you have a shoebox filled with a bunch of obsolete connectors collecting dust in your garage, or worse, your parents’ house. Each of these cables and display connectors can only fulfill one specific connection. You can’t mix a VGA cable with a tri-colored composite cord and expect it to work; the connections look and act differently from each other. This was the norm for years.

Today, the trend is moving toward fewer display connectors that handle more. This will be great news for your parents, who will bug you a little less about clearing out those ratty shoeboxes. They’ll still bug you, just about other stuff.

Connectors now are able to handle multiple signal formats, so they can carry video, audio, and data information while often being able to charge the connected device. This’ll be familiar to anyone who’s got a smartphone, and in fact, this connectivity trend is being driven by consumer devices like advanced phones and tablets. Compare this to a decade ago, where connections were driven by advances and needs of professional equipment.

The interfaces through which we connect our devices are getting smaller, denser, and faster, much like the phones themselves, now sporting fewer ports. The interfaces can make decisions about display resolutions, audio formats, Ethernet connectivity, and can receive and send control signals, so you don’t have to sweat the details. All of these interfaces use Extended Display Identification Data which allows your video card to configure itself automatically. This is what makes your display rotate to landscape mode when you plug in your phone to display content on a TV. What’s more, wireless connections are also right around the corner.
