VGA Connector: What is a VGA Cable & Port?

VGA Connector Guide - the Port and Cable Explained

Updated:

A VGA cable can help send a laptop image to your TV, but it can be more complicated than that. Learn about the VGA port and if you can convert VGA to HDMI.

A VGA cable is mainly used to connect computers and laptops with screens and monitors, although you may also find this connection type on older AV equipment.

While a VGA port is a relatively old connection type now, it still has its uses, so don’t be surprised if you run into one of these from time to time.

There are still plenty of times that you might need to use a VGA connection.

And, you might be surprised to know that you can connect VGA to HDMI, which can be extremely useful if you want to connect older equipment together.

But that’s not all; you can connect HDMI to VGA too!

Read on to find out more about this connection type and consider its use.

What Does a VGA Port Look Like?

The VGA connection on your device looks like this:

Blue VGA connector

It is a female 15-pin D-sub port.

The ‘D’ shape ensures that VGA cables will only fit one way round, and it is often colored blue or black.

Depending on your device, the connector will either be a video input or output.

It may be labeled as ‘input’ or ‘output’ on the device itself, but if not, you should know what it is by considering what the device is for.

For example, on a desktop computer or laptop, the VGA port will be a graphics card output for connecting to a monitor or screen.

But, it will probably be a video input for receiving video from a source device on a projector.

What Does a VGA Cable Look Like?

A VGA cable looks like this.

It will have a male 15-pin D-sub connector, which obviously fits nicely with the female connector on your hardware.

Be careful when plugging this in, as you can bend the pins unless you are careful. If you find it isn’t going in easily, check for any bent pins on the cable end.

If you see some that aren’t aligned properly, you can carefully straighten them up with tweezers or a small pair of pliers.

What Does a VGA Connection Do?

A VGA connection sends analog video signals between compatible devices. You would usually use a VGA connector on your AV equipment to connect your PC or laptop to a projector or television.

VGA connections usually receive an analog RGB signal from a device – the kind of video signal you get from a computer – and VGA supports standard and high-definition resolutions.

A VGA cable does not transmit audio signals, so a separate audio connection will be required to hear any audio.

The standard 15-pin D-Sub connector is common on many computers, and therefore you can use VGA male-to-male cables to send a computer image to your TV screen.

When Should You Use a VGA Connector?

A VGA connection is often used if you want to connect your PC or laptop to your TV or projector.

However, if your computer or laptop has a DVI or HDMI output, then it would usually be better to connect using this type of connection.

If your output device only has a VGA port – or has no spare DVI or HDMI inputs – then a VGA connection will still give you a good picture.

However, ensure you buy a good quality cable, as the cheaper VGA cables can often produce a poor image.

A Brief History of VGA Connections

VGA was developed in 1987 by IBM for an original display resolution of 640×480 pixels.

As VGA also became the standard video connection type for computers, VGA might refer to the standard VGA display resolution of 640×480 – or the 15-pin D-Sub connection.

Over the years, the VGA standard connection has been adapted for higher video resolutions, including Super Video Graphics Array (SVGA) and Extended Graphics Array (XGA).

A VGA connection now even supports high-definition formats like 1920×1080 and 2048×1536.

How to Get a Good Computer Image on Your TV Screen Using VGA

To get a sharp computer image on the TV screen, it’s best to set the output video resolution of the computer to match the native resolution of the TV.

If not, the image will appear stretched or blurred.

Also, you may not be able to fill the whole TV screen with a sharp image as the computer’s output resolution may not match the TV’s resolution.

If you are using a laptop, you will usually need to press a combination of keys to send the image to the TV – for example, function + F7.

This will vary between models and so consult your manual.

Does VGA Work With HDMI?

Although both support video signals, VGA won’t work directly with HDMI because they use different signal types and connectors.

VGA uses an analog video signal, whereas HDMI is a digital interface.

However, you can make this connection type work if you buy a compatible converter or adapter, although there are some limitations on what you can send.

Knowing which way you wish to convert the signal – VGA to HDMI or HDMI to VGA – is crucial because this will determine which type of converter you need.

How to Convert VGA to HDMI

To convert a VGA signal to HDMI, you will need to buy an adapter cable.

Sending a computer image to your television is more difficult if you have a VGA port on your computer – but you don’t have a VGA connection on your TV.

Most modern TVs will have several HDMI inputs, but maybe not VGA.

The VGA to HDMI scaler/converter pictured below supports sending from a VGA output to an HDMI input – but not the other way round.

CHECK AMAZON PRICE

You can also use the supplied 3.5mm male-to-male cable to send audio to your TV, so you will get both the picture and sound if required.

All you need to do is connect the VGA connector on the adapter to the VGA output connection on your laptop – then connect a separate HDMI cable from the adapter to one of the HDMI inputs on your TV.

There is a USB connection for devices that need additional power.

The above model supports video up to 1080p Full HD but will also support 1600×1200 (UXGA) and 1024×768 (XGA) – and the resolution you can send will depend on your laptop.

Just be aware that you won’t be able to send copyright-protected content because the HDCP protection for HDMI requires support from all devices in the chain – and a VGA connection doesn’t support HDCP.

How to Convert HDMI to VGA

For converting HDMI to VGA, you should be aware of some potential limitations.

You won’t be able to play copyright-protected material as there will be no end-to-end HDCP connection, which is required for copyright protection.

This will be a problem if you try to play movies from your DVD, 1080p or 4K Blu-ray player.

You may also require a separate audio connection.

However, if that isn’t an issue, then the HDMI to VGA adapter below will do the job just fine.

All you will need is to provide a suitable VGA cable to connect from the adapter to the VGA input on your display device.

You cannot use this to transfer audio; it is video-only, so you will need to make a separate audio connection from your source device to your display or speaker system.

VGA to DisplayPort Conversion

Of course, it may be that you are in the opposite situation.

You might have an older computer with a graphics card with VGA-only – and you need to connect it to a newer screen, TV or projector with a DisplayPort input.

In which case, you need to find an adapter that converts the video signal in the right direction.

Here is a VGA to DisplayPort adapter that does just that:

You will also need to connect the USB plug to provide power for the adapter.

What Is a USB to VGA Adapter For?

You would need a USB to VGA adapter to add a VGA output to a device that didn’t have one.

For example, you might have a projector with a VGA input and want to connect your laptop computer to display on a big screen.

But, many new computers don’t have a VGA output anymore, so you have a problem.

Fortunately, most computers do have plenty of USB ports. So, buying this adapter allows you to add a VGA video output to your computer, and you can easily connect your hardware together.

The model shown here is a popular example of a USB 3.0 to VGA adapter:

Frequently Asked Questions

Here are some quick and easy answers to common questions about VGA.

What is VGA?

VGA can refer to either the original video standard resolution of 640×480 or the analog video connection found on many multimedia devices. The connection is mainly used on computers and laptops for linking to display monitors but may also be found on projectors and TVs. These days, it is more common to use a digital video connection to transfer video like HDMI, DisplayPort and DVI.

What Does VGA Stand For?

VGA stands for Video Graphics Array.

How Many Pins Are on a VGA Connector?

A standard VGA D-Sub connector has 15-pins.

What Is a VGA Cable?

A VGA cable is for connecting VGA video inputs and outputs. Although an older connection type, many computers, laptops, projectors and TVs still have VGA connections, so you can use a VGA cable to send an image to your display device.

Which Is Better, VGA or DVI?

It is unlikely you will see much difference in picture quality between VGA and DVI-A. Just make sure that you buy a good quality cable because analog video can be adversely affected by electrical interference and long cable runs. A DVI-D connection is digital, which may work better than analog in some circumstances.
