What is VGA Full Form in a Computer?

In this topic, I will explain what is a VGA Full Form and its uses. There are so many different cables in your home, office, and computer that it can be hard to keep track of them all. The VGA cable is one of the most common, so it’s worth getting familiar with what it does, and how to use it correctly.

Here’s what you need to know about VGA cables – including how to identify them and the difference between male and female connectors, so you can identify the cables you have around your home or office and connect any new ones you buy.

VGA Full Form

Video Graphics Array (VGA) stands for Video Graphics Array. A full form of VGA cable is a visual-graphics array cable.

This cable was initially developed by IBM in 1987 and used to transfer video signals between computers, monitors, video output devices, and video input devices. Today’s digital televisions usually come with two types of ports – HDMI port or DVI port.


The History of the VGA Cable

For many years prior to 2007, standard computer monitors were most commonly connected using what’s known as an analog signal cable.

That is, when you connect your computer to your monitor, it sends out information in analog form. This older type of cable became outdated in 2004 when digital signals began replacing analog ones.

At that time, computers and monitors were usually connected with what’s known as a DVI (Digital Visual Interface) cable. These cables are very similar to each other; they just send out videos in different forms.

How it Works

A VGA cable transfers video information to your display screen. The cable may be connected to your display or your computer.

It has three main parts: an amplifier, two signal conductors, and shield connectors.

The amplified signals are transmitted from one end of the cable to another through either a 15-pin HDDB15 connector or a 24-pin HDDB15 connector that fits into holes on your display unit or motherboard.

The holes vary based on which type of cable you have – regular definition (VGA) cables, high definition multimedia interface (HDMI) cables, digital visual interface (DVI) cables, and personal computer monitor (DPM) cables –

so make sure you know what kind of connection you need for your system and/or hardware devices before purchasing any cables.


Different Types of Cables

When it comes to cables, there are many types. The most common type of cable you will find is RCA cables. These cables can be used for audio or video, though these aren’t usually referred to as VGA cables. If you want to use an RGB or RGBS signal, then you will need a specific cable in order to do so.

There are some instances where both types of signals can be sent over one line by using a special type of adapter known as a SCART adapter.

However, if your monitor doesn’t have such an input option on it, then you will need separate lines for each signal type.

Advantages & Disadvantages

Advantages of VGA Cable

The technology has been around for decades, which makes it one of the most commonly used connection types. The wiring in these cables is twisted to help prevent signal loss and interference.

The main downside to using these cables is that they cannot display at high resolutions, such as 4K or 5K.

As higher resolution screens become more commonplace, you will need to use HDMI or DisplayPort connections instead. However, if you only need a standard HD video display, then VGA cables will be just fine.

In addition, there may be compatibility issues with certain monitors and computers when using VGA cables. This can make finding compatible equipment harder than some other connection types.

Disadvantages of VGA Cable

Another downside to using VGA cables is that they can’t transfer audio signals, which means users must rely on their computer’s speakers (or headphones) for sound output.

Another issue to consider is compatibility between devices – different devices may require different kinds of connectors; there are several versions of VGA ports (15-pin D-sub), so even if your monitor supports VGA connectivity, your computer might not have a matching port available on its back panel.

The Importance of Having One

When it comes to getting quality video onto your TV, you can’t beat a VGA cable. They’re easy to set up and offer amazing quality at an affordable price.

No wonder most people use them in their home theaters! If you need to install one of these devices, follow these simple steps First, purchase a VGA cable.

Most electronics stores sell them for less than $10. Next, plug one end into your computer and run it along the wall until you reach your television.

Where to Get One

A VGA cable is necessary if you have an old computer monitor. They are relatively inexpensive and can be purchased at most electronic retailers.

For example, you can go to Best Buy or another large electronics retailer and ask for a 15-pin to 15-pin RGB (also called DB15) cable. Or, you could go online and look for them there; there are even multiple websites that sell cables specifically made for video gaming.

The prices range from $10-$20, depending on what type of cable you get and where you buy it from. And remember, since they’re so common, stores tend to have them in stock; otherwise they will just order one for you instead of wasting your time trying to locate one elsewhere.


As we mentioned above, in general, VGA cables are used to connect video output devices such as monitors and projectors to a computer or laptop. It’s important that you make sure your cable is HDCP compliant, meaning it can transmit high-definition content.

HDCP stands for High-bandwidth Digital Content Protection, which was created by Intel Corporation to protect audio/video content from being stolen or pirated.

If you’re buying a new PC with an integrated graphics card and you’ll be connecting it to an external monitor via HDMI or DVI, you don’t need to worry about getting an adapter cable.

However, if you’re going to be hooking up older hardware like projectors that only have VGA ports available, there are definitely some options out there for you.
