What is VGA? | How Does It Stack Against Other Connection Types?

VGA (Video Graphics Array) is a fifteen-pin display standard invented in 1987 by the International Business Machines Corporation. The Video Graphics Array uses an analog signal to transmit data. Thus, its resolution is lower, and its display output is of poor quality. 

VGA is used to transmit video signals from a computer to an external monitor. It is used in televisions and projectors with a VGA port. The VGA has a resolution of 640 x 480, which is not ideal for watching movies or gaming. The refresh rate of the VGA is 60Hz, so If you are using anything other than a DisplayPort cable or DVI to connect, you will be limited to around 100 Hz for your refresh rate - see how that works for 144Hz monitors.

The VGA cord has been replaced with advanced technologies such as the HDMI, DVI, and DisplayPort display standards. For example, new G-Sync monitors work over DisplayPort only and not HDMI or VGA, though they can still come with them.

Among its features, the VGA is characterized by its fifteen-pin connector. All the pins in the VGA connector have a unique function. The first three pins transmit red, green, and blue colors, respectively.

What is a VGA?

VGA, or Video Graphics Array, is a display standard that uses analog technology to transmit a computer (source) signal to an external display device. 

VGA cable is used to transmit video signals from a source computer to a monitor. However, the output quality is low because VGA uses analog signals to transfer data. Its resolution also limits the VGA cable from displaying top-quality output, which in turn may cause eye-strain. Nonetheless, monitors that are good for pretty much most purposes - see 24 inch monitors - can never be over-equipped with ports like VGA, DVI, and perhaps even a headphones jack.

The VGA cable features are,

  • Two screws are located on both sides of the cable end. The screws attach to the corresponding plug on the monitor for a firm connection. 
  • The VGA cable is also characterized by its fifteen-pin connector. An inspection of the inside of the VGA plug will reveal fourteen pins. The fifteenth is a hole that aligns the same to the pins. The setup of your system may make this feature vary. 
  • VGA display standard uses analog signal technology to display images, thus a lower quality video output.
  • VGA has a resolution of 640 x 480 and a refresh rate of 60Hz.

The VGA signal can be converted from VGA to HDMI signals using a VGA to HDMI converter. A VGA signal can also be converted to a DVI signal using a VGA to DVI converter.


What does VGA Stand for?

VGA stands for Video Graphics Array, a display standard that uses analog signal technology to transmit video data from a source computer to a monitor. The VGA was first established in 1987 to transmit video signals between a monitor and a computer. It was later replaced by advanced display standard technologies like the DVI port, HDMI, and recently, the DisplayPort. Most today's LED monitors come with various connectivity options, including VGA.


What is the Length of VGA Cables?

The length options of the VGA cables are listed below.

  • One hundred feet for a VGA cable with a resolution of 800x600 

  • Fifty to ninety-nine feet for a VGA cable with a resolution of up to 1280 x1024

  • Twenty-five feet for a VGA with a resolution of 1600x1200

You should note that the length of your VGA cable affects the signal strength. The strength of a VGA cable weakens with an increase in length. Consider the length range given below.

  • Twenty five-feet VGA cables produce a top-quality output display.

  • Twenty-six-feet to ninety-nine-feet VGA cables will produce a fine quality output display.

  • One hundred feet and beyond VGA cables will produce a low-quality output display. 

The length of the VGA cables can be extended using an ethernet cable. The ethernet cable can extend the length of the VGA cable to reach six hundred and fifty feet. However, you should note that the ethernet cable will need an extension if it goes past three hundred and twenty-eight (328) feet.

What is the Usage of VGA Cables?

The usage of the VGA cables is listed below.

  • The VGA cable is a linkage between the PC and a projector.  

  • The VGA cable transfers analog display signals from a PC to an external display device, like a monitor. 

VGA cables are compatible with monitors (see HP monitors), television sets, and projectors using analog-based technology. However, you can use a VGA port in a computer or monitor that does not support VGA input. To do this, you'll need a VGA converter. 

VGA to HDMI adapter converts the VGA analog signals to HDMI signals before they can be transferred to the secondary monitor. On the other hand, an HDMI to VGA cable will convert HDMI signals to VGA signals to be transmitted into an analog monitor. 

VGA to DVI adapter will convert VGA signals to DVI signals.

What Does the VGA Input Look Like?

The VGA input looks like a fifteen-pin D-shaped port. The VGA input is a female input that has holes corresponding to the pins on the VGA cable. The pins on the VGA connector cable fit into these holes during connection. The VGA input is typically colored blue or black. The D shape of the VGA input ensures the VGA connector connects with it in one orientation only. 

VGA input supports a VGA cable connection only. However, you can connect an HDMI cable to it using an HDMI VGA adapter. The adapter will convert the HDMI signal and turn it to a VGA signal to connect it to the VGA input.

How Does a VGA Cable Appear?

A VGA cable appears like a fifteen-pin D-shaped connection at its end. The fifteen pins are aligned in three rows, with each row having five pins. 

The VGA cable has a male connector at the end. The D-shape design allows the cable to fit well in the VGA port of your device. 

When connecting the cable, take precautions not to misalign the pins. Check the pins to confirm that none is bent if you feel some resistance while plugging the cable in. If bent, straighten them with pliers before you plugin again.


What is the Origin of VGA Connectors?

The VGA connector was introduced in 1987 by the International Business Machines Corporation. The intent of the VGA creation was to serve as a connection between video cards and display devices. 

The first VGA connector had a resolution of 640 x 480 pixels. This resolution did not limit it as the VGA cable can produce a 1080 pixels resolution or more.

Starting from 1987, when it was established, the VGA connector has been widely used in computers and laptops as a connection cable to display monitors. 

The VGA connector was slowly replaced by advanced technology display standards. These display standards include the HDMI, VGI, and DisplayPort. The new display standards have higher resolutions, higher refresh rates, boosted bandwidth, and supported digital signals to transmit video and audio signals. However, the VGA connector is still in use today but in a less extensive application. Due to their bulkiness, they are frequently omitted from portable monitors and other niche products.

Over the years, VGA developers have enhanced the VGA technology. The VGA technology has seen the development of:

  • Standard VGA has a horizontal resolution of 640 and a vertical resolution of 480

  • The SVGA with a horizontal resolution of 800 and a vertical resolution of 600

  • The XGA came next, with a 1024 horizontal resolution and a 768 vertical resolution

  • SXGA followed sooth with 1280 horizontal resolution and 1024 vertical resolution

  • UXGA came last with a resolution of 1600 (horizontal) and 1200 (Vertical).

The advancement in the VGA technology allowed it to produce an aspect ratio of 4:3, which is typically square. 

Who Invented VGA Cables?

The International Business Machines Corporation invented the VGA cables. The headquarters of the company is at Armonk, New York. The corporation was established in 1911 by Charles Ranlett Flint and aimed at advancing information technology. Thomas Watson became the corporation's manager in 1914. In 1924, Thomas Watson renamed the company to its current name. 

Three individual companies merged to form the IBM corporation. These companies were office products specialists, such as the punch card tabulators. 

In 1933, the corporation got involved in electric typewriters. IBM developed high technology electromechanical calculators, which were used in world war two. A little while later, the corporation stopped developing these systems. 

In 1952, Thomas Watson Jr, Watson's son, assumed corporate leadership. Thomas Watson Jr. funded and restarted the development of a data processing system project to allow its continuation. The company prevailed under his leadership, and in 1960, the company became the leading in computer manufacturing.

In 1981, IBM shifted from producing mainframe computers to produce personal computers (IBM Personal Computer). In 1987 the company developed the VGA cable to be used as a display standard. The VGA cable was used to transmit video signals from a video card to a display unit.

What are Cable Bandwidths of VGA?

The maximum bandwidth to be sent through a VGA cable is 116 MHz which is, unfortunately, too low for top end 240Hz monitors out there . UXGA has the maximum bandwidth range, while the standard VGA has the least bandwidth, with a range of 14 MHz. 

Here is the breakdown.

  • Standard VGA - 14 MHz
  • SVGA cables - 27 MHz
  • XGA cable - 48 MHz
  • SXGA cable - 79 MHz
  • UXGA cable - 116 MHz

You should note that VGA cables use analog signals that degrade with an increase in cable length. 

The signals from the source computer are converted to analog signals before being fed to the VGA cables. The conversion process also degrades the signal to a lower value. 


How Much Do VGA Cables Cost?

VGA cables cost around $9.0 for six feet long cables. Ten-feet long VGA cables cost an average of $10.0, while fifteen-foot VGA cables cost an average of $12.5. 

These are the average price ranges for standard VGA cable to VGA cable.

VGA cables are a cheaper option compared to the DisplayPort display standard and you'll find them on most monitors under 200 dolars. It will be economically viable to buy a DisplayPort to VGA adapter instead of buying a new video card.

What are the Benefits of Using VGA Cables?

The key benefits of using VGA cables are:

  • VGA cables are cheaper than other display standards.
  • VGA has thumb screws on its connectors. This holds the cable firmly in place so that it doesn't disconnect accidentally.
  • VGA signal range can easily be extended using amplifiers.
  • VGA cables are simple to set up during connection. The pins on the connector fit well in the monitor port.
  • VGA cables presume the same connector design, so one VGA cable can connect to several monitors or projectors with a VGA port.
  • VGA cables' signals work perfectly when their cabling is done correctly and in good condition.
  • VGA signal structure allows for easy division using appropriate amplifiers. 
  • VGA cable can be split into five different wires for use in other devices.
  • VGA cable signals run for a long time before they start degrading.
What are the Cons of Using VGA Cables?

The cons of using VGA cables include poor resolution, high purchase price, and its signals degrade quickly with an increase in cable length. 

The VGA cons are listed below.

  • VGA cable produces low-resolution output.
  • VGA cable degrades video signal quickly with an increase in cable length.
  • VGA cable signals have high interference cases.
  • VGA cables with lower gauges can not transmit signals over a more extended range.
  • The VGA cable connector has fifteen pins, with one left unused. This increases the chances of sending the other pins, resulting in distortion of the image.

What are the General Problems and Solutions about VGA Connection?

The common problems of VGA cables are listed below.

  • Screen flickering 
  • Inaccurate image color on the display interface
  • A sudden blackout of the monitor
  • No signal issues
no signal sign on screen

To troubleshoot common problems with the VGA cables, try the fixes discussed below.

  • Inspect your Cable Connection

Inspect the VGA cable and any other cable you've connected to your computer and monitor - see connection types. Make sure none of them is loosely attached or incorrectly plugged in. Also, ensure you plug in the cable if it has accidentally slipped off. Fasten the cable if it is loose.

  • Test your VGA Cable

A faulty cable may result in issues with the signal transmission. Unplug the cable from the monitor and the computer and test it on another device. If the cable still has challenges transmitting the signal, then the problem is with the cable. In this case, you'll have to replace it. You can also disconnect the VGA cable and use a different cable to connect your PC and the monitor. If the new cable works correctly, then your VGA cable is faulty. And you may need to replace it.

  • Inspect your Monitor and the Computer

If the problem is not with the cable, then either the monitor or the computer is faulty. Connect the device to a power source and Power it on. If it doesn't turn on, then it may be faulty. 

To fix the no signal problem, try either of the following fixes.

  1. Restart the computer

You can restart the PC when it shows a 'no signal' problem. 

Follow the procedure given below to do this fix.

  1. Shut down your computer and monitor
  2. Disconnect the power cables of the monitor and the PC
  3. Disconnect the VGA cable from the computer and the display output 
  4. Give it some time 
  5. Plugin back the VGA cable to the monitor and the PC
  6. Plugin back the power cables
  7. Turn on the monitor and the PC

After doing this procedure, your PC should regain its signal.

  1. Update your Graphics Driver

No signal problems can result from an outdated or faulty graphics driver. If you experience a no signal problem, download and install the latest graphics driver. You can also use Auslogics Driver Updater to identify the drivers that need an update. The program scans your PC system and notifies you of any driver that needs an update. 

keyboard button

To use Auslogics Driver Updater, follow the procedure given below. 

  1. Download the Driver Updater, then install it.
  2. Open the updating tool and let it scan for driver problems.
  3. Follow the set of instructions you'll be prompted on the screen. 
  4. Restart the PC.

If the fix was successful, your VGA should start working correctly.  

  • Inspect the VGA connection

Inspect the VGA connection to confirm that you've connected the DisplayPort cables correctly. Ensure the VGA is attached to the correct port and in the correct way. You'll also need to confirm that the VGA cable is not loosely attached to the port. You may need to disconnect the VGA and connect it again. Gently push the VGA until it attaches itself to the female port on the monitor. 


Can VGA Connection be Used for Monitors?

Yes, VGA connections are used for monitors. The VGA cable transmits analog video signals from a video card or a computer to a monitor. VGA splitters are used to separate analog video signals into several signals, which are then channeled to several displays. By doing so, the signal is extended to several monitors.  

VGA signals are not limited to VGA compatible monitors alone. The VGA adapters convert the analog VGA video signals to other display standard signals and feed them to AVG non-compatible monitors. ts biggest advantage is that it is easily available everywhere.

The Benefits of a Computer Monitor with VGA?

Many companies provide monitor as well as VGA cable for free, but since the invention of digital cable, it has become a bit difficult to find it in the local market. Apart from this, VGA cable is slightly cheaper than other diesel cables, but this does not mean that you should compromise on picture quality.

As far as professionals go, here are the options: 

Graphic Designers

As far as graphic design go, you shoud really stick with a 4k monitor and for that matter, one that offers the best possible performance. Ideally, graphic design monitors should come with as many types of ports as possible. High-end monitors tend to include DisplayPorts insteas of VGAs to handle high resolution, color saturation, and internal calibration, and it is rightfully the most useful connector for creatives.

Photographers

Photographers should avoid VGA as a connection type. For that reason VGA port is often replaced with a Mini DisplayPort on newer monitors. Same goes for DVI. If you own a monitor for photo editing and a fitting graphic card with drivers that support 10 bit per color, there will be lots of benefits to go with a DisplayPort connection. You'd want to ensure that your audience is looking at most realistic images, which some of these top Dell monitors may bring about.

Programmers

Features like high resolution, vibrant colors, clarity, response time and refresh rate are important in monitors for programming and are welcomed when you're spending long hours at work. Also, monitor size and orientation are equally relevant. Through daisy-chaining or hub, something that old-school VGA connection can't support, DisplayPort will allow you to keep your work space unclustered. We suggest taking a look at Asus monitors which might help you with your multi-tasking.

Traders

For multiple displays set up and office desktop stations, DisplayPort offers more flexibility and power than slightly outdated VGA. Top monitor for traders will make sure that the trade goes smoothly. The screen size matters, too, as with better resolution, you get the better image quality, and most importantly with flicker free, and anti-glare screen features, your eye-safety is well-adressed. We tip these Samsung monitors to do the trick.

What is VGA Splitter?

VGA splitter is an interface that separates VGA video signals into several channels, which are then transmitted to different output displays. The VGA splitters are commonly used in TVs and projectors connected with the computer. They also connect a computer to several monitors and allow each monitor to display different information. 

The VGA splitter works by intercepting video signals sent from the PC. This allows the signals to pass from the computer to the monitor(s) via the separator. The splitter will then split the video signal into several channels before sending them through several channels to the monitors. The VGA splitters are designed to boost the video signals before allowing them to flow to the monitors. 


What is VGA Adapter?

A VGA adapter is a connecting cable interface that connects a VGA cable to other display standards and helps convert the analog VGA signals to match the new display standard. 

Several VGA adapters exist, and each has a unique role. A VGA to DisplayPort Adapter converts the VGA analog video signals to digital DisplayPort signals. 

VGA to DVI adapter will convert analog signals from the VGA to DVI signals. The VGA to HDMI adapter links the VGA to an HDMI. The adapter converts analog VGA video signals to digital HDMI signals.

How to Convert DVI to VGA

To convert DVI to VGA, you can use a standard cable that has a VGA connector and DVI connectors on either end. Plug the cable end with the DVI connector to the DVI computer port. The other end having the VGA connector should be connected to the VGA monitor. By doing so, the cable converts DVI signals to VGA signals. 

You can also convert DVI signals to VGA by using a DVI to VGA adapter. Just like the cable, the adapter has a DVI connector on one end and a VGA connector on the other end. The adapter converts DVI signals to analog VGA video signals. The adapter is connected between a DVI-compatible computer (see post) and a VGA-compatible monitor. 


How to Convert USB to VGA

To transform USB to VGA signals by using a USB to VGA adapter. This adapter connects a USB- compatible computer to a VGA-compatible display device. 

To use the USB to VGA adapter, plug in the adapter to the USB port on the PC. You'll then need to plug in a VGA cable to connect the adapter and the monitor. Also, you will need an appropriate adapter to connect your Mac Mini monitor which, like most other Apple products, aren't equipped with a VGA port, though they come with a Thunderbolt cable port.

The USB to VGA adapter has the following benefits.

  • The adapter links a computer and a monitor or projector.
  • The adapter provides a VGA port to the PC. 
  • The adapter provides a resolution of 1080 pixels.
  • The adapter can link to more than one monitor.
