The average person who doesn't work in IT probably has no idea what the different types of video cables are, let alone what they do or why you need them. You probably don't need to be an expert on these things either. Still, it can be good to have some working knowledge to buy the right video cable and avoid overspending on the equipment you don't need.
The first thing you need to know about video cables and wires is that there are many different types of cables. Understanding how they differ from one another can help you pick the right one for your needs. So, how many different types of video cables are there? Technically, the answer to that question depends on how you define a type of video cable. In reality, however, 26 different video cables are used by businesses, schools, government agencies, and consumers every day.
This article will take you through 26 of the most common types of video cables, their primary functions, and what equipment they typically connect to in layman's terms to become an expert on the subject yourself.
Two Primary Types of Video Cables
The first distinction you need to make when it comes to video cables is the difference between analog and digital cables. Analog cables transmit an analog signal, a continuous wave that can take on any value within a given range. Digital cables, on the other hand, transmit digital signals, which are a series of discrete pulses that can only take on a limited number of values.
The vast majority of video cables you'll encounter these days are digital cables, as the transition from analog to digital signals has been taking place for many years now. However, there are still a few analog cables in use, so it's important to know the difference.
Analog Cables
Most people have moved on from analog video cables, but some die-hards still hold onto their VHS players and CRT TVs. If you're one of those people, you might be wondering what kind of cable you need to connect your devices. The answer is an analog video cable. Analog video cables are designed to carry an analog signal produced by most older devices.
These cables typically have three pins. They can be used to connect various devices, including VCRs, DVD players, and game consoles. If you're still using analog devices, an analog video cable is a perfect way to keep them connected.
Digital Cables
There are a variety of digital video cables on the market, and it can be confusing to know which one you need. The most important thing to keep in mind is the resolution of your display. If you have an HD television, you'll need a cable carrying a high-definition signal. The most common type of high-definition cable is HDMI, which can take both video and audio signals.
If you have an older television, you may need a different type of cables, such as component video or S-video. It's also essential to ensure that the cable you choose is compatible with your equipment. For example, some cables can only be used with specific devices, such as Blu-ray players or video game consoles.
Different Types of Video Cables and Their Functions
Perhaps you need a new video cable, wondering which one is right for you. This section will take you through some of the most common types of video cables and their primary functions.
Apple Display Connector
The Apple Display Connector (ADC) is a proprietary connector used by Apple Inc. to connect their computers and displays. It was first introduced in 1998 with the release of the iMac G3, which was later used on the PowerBook G4, iBook G4, MacBook Pro, and Intel-based iMac and Mac mini. The ADC connector carries digital video and analog video signals, power, and USB data.
It was designed to simplify the process of connecting an external display to a Mac computer. However, the ADC connector is no longer used by Apple. They have switched to using HDMI or DisplayPort connectors instead. While the ADC connector is not used anymore, it can still be found on some older Apple displays.

Length
The length of the video cable is also an important factor to consider. In general, the longer the cable, the more expensive it will be. However, you'll need to make sure that the length of the cable is appropriate for your needs. For example, if you're only going to use the cable to connect a DVD player to a TV, you won't need a very long cable. On the other hand, if you're going to use the cable to connect a computer to a projector, you'll need a longer cable.
Connector Type
As we saw earlier, the connector type is also an essential factor to consider. Be sure to check the type of connector used on the devices you want to use the cable with. Otherwise, you won't be able to connect the two devices properly.
Pixel Resolution
The pixel resolution is the number of pixels displayed on a screen. The higher the pixel resolution, the better the quality of the image. When choosing a video cable, be sure to check the maximum pixel resolution that it can support.
Frequency Response
The frequency response is the range of frequencies that an audio cable can reproduce. The higher the frequency response, the better the quality of the audio. When choosing a video cable, be sure to check the frequency response to be sure that it can reproduce the audio frequencies you need.
Cable Gauge
The cable gauge is the thickness of the wire—the thicker the wire, the better the signal quality. When choosing a video cable, check the cable gauge to ensure it's thick enough to carry the signal you need.
Price
Of course, price is also an important factor to consider. Video cables can range from a few dollars to a few hundred dollars. In general, the more expensive cables will offer better performance. However, you'll need to decide how much you're willing to spend on a video cable.
