The process of projecting the screen of a laptop onto a television is made easier by the use of a VGA connection; however, there are other considerations to take into account. Find out whether the device has a VGA port and whether it is possible to convert VGA to HDMI if it does have a VGA port.


Even though personal computers and laptops are the most prevalent devices to use VGA cables to connect to displays, you could still find them on older AV devices. Do not be surprised if you stumble onto a VGA port every once in a while; despite the fact that it is an older form of connection, it is still helpful in certain circumstances.


Despite this, there are still a great number of circumstances in which a VGA connection is required. In addition, it is possible to convert VGA signals to HDMI, which is a feature that is very useful when it comes to connecting older equipment. In addition, an adaptor that converts HDMI signals to VGA output can be purchased.

The VGA Port Looks Like What?

The following should appear on the VGA port of your device:


A female D-sub 15-pin connector is featured on the blue VGA adapter. VGA cables can only be plugged in one way due to their distinctive ‘D’ form and blue or black colouring, which are industry standards.

It is dependent on the device that you are utilising as to whether the connector will act as an input or output for a video signal. It’s possible that the inputs and outputs of a device are labelled plainly as such, but even if they aren’t, you can determine what they are by thinking about the function of the device.


One example of an output that can be connected to a display device is the Video Graphics Array (VGA) port, which can be found on desktop and laptop computers. However, it is quite likely that there will be a video input that enables the projector to obtain video from a device that is external to the projector.

How Does a VGA Cable Appear?

This is an example of a VGA cable’s appearance:


To be more specific, it will have a male 15-pin D-sub connector that is designed to be compatible with the female connector that is already present on your existing gear.

If you are not careful when plugging it in, the pins can easily be bent out of their original position. If it is difficult to insert the plug, check the end of the cable for any pins that may be bent. It is possible to gently straighten any that are crooked using a pair of tweezers or a pair of little pliers.

Various Forms

Connectors for video graphics arrays (VGA) come in a variety of flavours. The video graphics array (VGA) connector is also known as the RGB connector, the Mini 015, the HD15, the Mini D15, the HDB-15, the DB15, and the Mini sub D15.


Connectors with male pins include the DB13W3, HD15, 5BNC, 4BNC, etc. Therefore, “connection one” is the standard name for this category. HD15 female, HD15 male, HD 15 female, or a 6PIN Mini-Din PS2 male, 4BNC male, 5BNC female, HD 15 female, or a USE B male cable are alternatives.

The VGAs splitter, the sun DB13W3, the VGA adapter, the KVM, the VGA to BNC breakout, the SVGA, the VGA to RCA breakout, and the BNC to BNC breakout cables are but a few of the many varieties of VGA connectors available. Several alternative plug styles are offered for these cables.


The VGA Connector has the following features:

Depending on your needs, you can choose from VGA cables and connections ranging in length from 0.75 feet to more than 30 feet. Not only that, but you can get these cables in a range of hues, including black and beige.


Double or triple shielding is also included in some cables. The type and length of these connectors determine the retail price. Depending on the application, many cables may be utilised. A single connector on one of these lines can cost anything from $10 to $400.

What purpose does a VGA cable serve?

When two devices are compliant with the Video Graphics Array (VGA) standard, it is possible for analogue video signals to be transmitted between them. In most cases, you will need a VGA connector in order to link your desktop computer or laptop to an audiovisual (AV) equipment such as a TV or projector.

The visual output of a computer monitor is an analogue RGB stream, and a VGA connection is capable of handling resolutions in both standard definition and high definition. A separate audio connection is required in order to listen to sound while using a VGA cable; this cannot be done on its own.

Because most computers use the same 15-pin D-Sub connector, you can use VGA male-to-male adapters to connect your computer to your TV. This will allow you to view your computer’s display on your television.

When Should a VGA Connector Be Used?

It is usual practise to utilise a VGA connection when connecting an internal display (like that of a desktop or laptop computer) to an external display (like that of a TV or projector). However, if your desktop or laptop computer has a DVI or HDMI output, it is strongly suggested that you make use of one of those cables instead.


If your output device only has a VGA connector or if it does not have a DVI or HDMI input accessible, you should not immediately rule out using a VGA connection because it still produces a high-quality image. Be wary of inexpensive VGA cables, though, as these cables frequently result in a display that is pixelated at the other end.

A Brief History of VGA Connector

The Video Graphics Array (VGA) standard, an analogue interface for computer monitors, debuted in 1987. IBM created this standard for computer display connections as an improvement over the older CGA (Color Graphics Adapter) and EGA (Enhanced Graphics Adapter) interfaces.

Video Graphics Array (VGA) was a standard for connecting computers to monitors and other displays using a 15-pin connector and cable. Multiple resolutions were available, with 640×480 being the highest. Other supported resolutions included 800×600 and 1024×768. The RGB (red, green, and blue) standard used to transport video information over the interface allowed for a respectable degree of colour fidelity.


The Video Graphics Array (VGA) interface has steadily gained traction over the years to become the de facto standard for computer monitors. CRT displays, which were extensively used with VGA, fell out of favour after the arrival of flat-screen LCD monitors in the early 2000s. Because of this, digital display interfaces like HDMI and DisplayPort were created to facilitate better video quality and higher display resolutions.

Although other digital interfaces have gained in popularity, VGA is still commonly used, especially in older computers and in industrial and commercial contexts. As a result of the necessity to transform digital signals to analogue ones before they could be delivered over the VGA interface, VGA was also still utilised in some circumstances when older equipment needed to be connected to newer screens. Further drop in VGA utilisation has occurred in recent years as digital interfaces have become the norm for connecting screens. There are still many places where VGA is used, especially in older systems and devices.


To sum up, VGA was a game-changer for computer monitors and its effects are still being felt today. Despite being supplanted by digital interfaces, VGA is still a popular choice for computer monitors. Its introduction cleared the path for the development of contemporary digital display interfaces and helped set the norm for computer display connections.

Which VGA Connector Should You Buy?

Several factors, such as those listed below, can be used in the selection of a VGA connector.

Brand name is a major factor in determining the quality of a connector. Cable power, RS Pro, Matrox, and StarTech are among of the most well-known manufacturers of VGI connectors.

On the Basis of Its Duration
To prevent visual signals from degrading due to their short length, the connector should be as long as possible. With the hope of preventing signal interference and preserving the cable.


Connector Pins with a Gold Finish
Gold plating the connector’s pins makes them a more effective conductor than copper plating. A faster and more reliable data transport is guaranteed by the gold plating.

Signal Interference Protection
VGA connection cables are vulnerable to signal interference from radio frequency and electromagnetic fields. Therefore, designers must construct the wire with a number of shielding layers. This feature ensures that the data transit in the cable is uninterrupted by any signal interference.


Adapter for use with male to female and female to male cables
Carefully choose the cable according to your needs, such as male to female or male to male. For instance, a ferrite bead and a male-to-male cable, such as an HD15 SVGA cable, are used with a male-to-female cable, which is used to connect a laptop, and a male-to-female connection is needed to add length to an existing cable.

VGA Port Orientation
You can find VGA connectors in both male (pins/plug) and female (socket/holes) forms. Position relative to the connector gender is used to identify VGA connectors.


Different VGA adapters, splitters, and extenders may be required to make a functional connection for a given system, depending on the precise cable type used and the specific pattern of the connection you need to build at the computer or monitor end.

The following are the several VGA connector genders that are currently available.

  • Male to Male
  • Male to Female
  • Female to Male
  • Female to Female

VGA Cable Connection Method for PC and TV

When connected to a monitor, a user can interact with a desktop PC. The desktop monitor displays the operating system’s graphical user interface (GUI) and other software applications, allowing you to see what you’re doing while you type, play games, etc.


When it comes to flat-panel displays, you can choose between LED and LCD. Displays like these can be joined to a computer via a VGA, HDMI, DVI, USB-C, or Display Port connection. USB-C, the Display Port, and HDMI are modern connections, whereas DVI and VGA are older options.

With a VGA cable, a computer can be linked to a TV in the following fashion. You’ll find a detailed explanation of the process down below. A VGA cable is used to join a home theatre PC to a TV. You can plug in the PC end into a TV port, and the TV end into a computer.

  • Plug the 3.5 mm audio wire into the computer’s headphone jack. Get some speakers, or hook up the TV’s audio input, and listen to it through there.
  • Select “Control Panel” from the menu that appears after clicking “Start.”
  • To modify the screen’s resolution, go to the Display menu.
  • If you select TV from the menu, you’ll see a pull-down menu with this choice.


The following are some of the benefits of using a VGA connector.

  • A VGA cable makes it simple to link many different types of electronic devices together, including televisions, computers, CRT monitors, and more.
  • In addition to providing stability, it aids you by facilitating faster reactions and easier movement.


The following are some of the drawbacks of the VGA connector.

  • It’s not as resolving.
  • The media player does not support audio or 4K video.
  • It is no longer relevant for today’s desktop and laptop computers.

How to Use VGA to Get a Good Computer Picture on Your TV Screen?

Adjusting the computer’s output video resolution to be the same as the native resolution of the television will result in an image that is crisp when viewed on the television.

If you don’t, the picture will have a distorted and stretched appearance. Because the output resolution of the computer may not be the same as the resolution of the television, you may not be able to fill the entire screen of the television with a sharp image if you use the computer.

Does VGA Work With HDMI?

It is possible that you will need to press a combination of keys on your laptop, such as function and F7, in order to transfer the image to the television. This will be dependent on the model that you have, so make sure to consult the handbook.

Can HDMI be used with a VGA monitor?

While both VGA and HDMI are capable of displaying video, they cannot be used together directly due to their differing signal formats and interfaces. VGA is an analogue interface, while HDMI is digital. With the right converter or adapter, however, you can make this connection type function, albeit with some data transfer restrictions.

Which type of converter you require, whether from VGA to HDMI or from HDMI to VGA, depends on which direction you wish to convert the signal.

A Guide to Changing from VGA to HDMI

You will need an adapter cable to change the VGA signal to an HDMI one. Having a VGA port on your computer but no VGA connection on your TV makes sending a computer image to your TV more challenging. While VGA may not be supported by newer TVs, most will have several HDMI ports.

The scaler/converter from VGA to HDMI shown below only works in one direction (from VGA output to HDMI input). The VGA connector on the adapter plugs into the laptop’s VGA output port, and an HDMI cable runs from the converter to a TV’s HDMI port.

If your gadget needs more juice, you can plug it into the USB port. It’s up to your laptop’s capabilities, however the aforementioned model can handle resolutions of up to 1080p Full HD, 1600×1200 (UXGA), and 1024×768 (XGA). Note, however, that a VGA connection does not support HDCP, thus you will be unable to send copyright-protected video over it.

A Guide to Changing from HDMI to VGA

There could be some restrictions while converting from HDMI to VGA. Since copyright protection requires an end-to-end HDCP connection, you won’t be able to play any copyright-protected content. It will be unable to watch movies on your DVD, 1080p, or 4K Blu-ray player because of this. There could be a need for a separate audio jack as well.

Multiple platforms, including computers, laptops, Chromebooks, the Xbox One, and the Wii U, are supported for delivering video.
In contrast, the Sony PS4 and a few Apple products, which use a low-power HDMI output connector, are not supported.

Does the DisplayPort to VGA Converter Work?

DisplayPort to VGA conversions are available. Any device having a DisplayPort output can be connected to a VGA input with the purchase of an adapter.

In the same way that an HDMI to VGA converter is required to transfer signals from one format to another, a DisplayPort to VGA adapter is required to do the opposite. The adapter depicted below is capable of doing the job, and it supports a wide variety of resolutions in addition to 1080p Full HD video, such as 1920 by 1200 at 60 frames per second, 1280 by 768, 1680 by 1050, and 1024 by 768.

To connect the adapter to the display’s VGA port, you need just supply an appropriate VGA cable. This only supports video transmission, so you’ll need to use a different cable to get sound from your source to your TV or stereo.

How to convert from VGA to DisplayPort

Of course, you may be in the inverse situation right now. Sometimes you’ll need to hook up an older computer with a VGA-only graphics card to a newer display, TV, or projector that only has a DisplayPort connector.


The solution is to track out a suitable adaptor that performs the necessary conversion of the video signal. You will be able to send an HD picture with a maximum resolution of 1920 by 1080 at 60 hertz.

Connect the included 15-pin D-Sub male connector to the VGA output for video output, and the 3.5mm connector to an audio output for sound. Connecting the USB plug supplies electricity to the adaptor.

What Is a USB to VGA Adapter For?

A USB to VGA adapter allows you to see digital video and computer images on a single cable. If your device doesn’t already have a VGA output, you can get one with the help of a USB to VGA adapter. You can connect your laptop to a projector with a VGA port to display its contents on a larger screen. Yet many modern PCs lack a VGA output, making your situation problematic.


The number of available USB ports on modern PCs is usually rather large. The addition of a VGA video output to your computer is a breeze with the help of this adapter. Your computer’s OS is the primary factor to think about. Only 800×600 at 60 frames per second will be possible via USB 2.0 connections. However, what if you don’t use Windows? Then you’ll need to go out and get a new adaptor.

Connecting via USB-C eliminates the need for drivers or software on a wide range of gadgets, including Thunderbolt 3-equipped MacBooks, iPads, laptops, tablets, and phones. Be sure to double-check with the maker for a full list of compatible gadgets before making a purchase.


In conclusion, the purpose of this article was to provide an overview of the VGA connector, which is mostly utilised for the purpose of connecting display devices, such as a computer to a projector, TV, or monitor. The HDMI, DVI, Connector, and Display Port cable are all responsible for the current transformation of this connector, which can be found in regular use today. I have a question for you: what exactly is the difference between a VGA connector and an HDMI connector?
