Video Cables - CompTIA A+ 220-1201 - 3.2

If you're connecting a computer to a screen or really any type of consumer electronics to a video display device, then you're probably using HDMI. This stands for highdefinition multimedia interface. This sends both audio and video through the same digital connection and it has about a 20 meter maximum range before you start to lose

too much signal and start seeing blockiness on the screen. This is one of the most common connector types that you'll find on today's monitors and televisions. It's a 19pin connector, and it's referred to an HDMI as a typea connector. Here's a video adapter that has a number of different outputs. It has DVI and display port, but it also

has a HDMI connection right here at the bottom. You can see that it's almost in the shape of a rectangle, but the bottom corners are indented in just a bit, which means that an HDMI cable would be the only thing that would fit into that interface. On that picture of the display adapter, we saw that one of

those interfaces was a display port interface. Display port is a video format that is also able to send audio and video over the same connection. and it was one of the first display type connections that sent it in a packetized form very similar to how you might send information over an Ethernet network.

This also has some compatibility with both HDMI and DVI. You can use a passive adapter to convert between display port to HDMI or display port to DVI. On some devices, you may find that the display port interface is the smaller style known as the mini display port. But on desktop computers and video interface

cards, you'll probably find the full-size display port connector. Notice that the display port connector has small little locks along the top of the connector. And when you plug it into the interface, it tends to lock in place. This means that connector will not accidentally pull out of that connector. And usually there's a button along the
