VGA is short for Video Graphics Array, a technology that enables computer monitors to display high-definition video. If you want to share a screen with a friend, and don’t know where to begin, this guide is what you’re looking for!
There are many confusing terms that can be seen with Linux, but there is one, that has a meaning that is fairly clear to everyone, regardless of what their interests and background. This term that very few people seem to understand is VGA. VGA has a translation of “Video Graphics Array”, which is what you normally see when you connect your display to your computer. VGA is the most widely used graphics interface for connecting a monitor to a computer.
A VGA, or VGA or video graphics adapter, is a type of video graphics card that is built into many newer computers. Basically, it’s a circuit board that handles all the graphics processing in a computer. If you’re not into technology, you may not know the difference between a VGA and a DVI or HDMI connector. Neither do most computers. And that’s why I wrote this article.
This article will tell you everything you need to know about VGA cables, so continue reading!
VGA stands for Video Graphics Array.
The abbreviation VGA stands for Video Graphics Array. It’s a video standard that was created in the 1980s and has been around for a long time. It’s still popular today since it’s simple to use, adaptable, and affordable.
A VGA cable links a computer to any monitor or television. The important component is commonly gold-plated connections, which transport video signals through an electrically conductive medium like metal. Male and female VGA connectors are available. It is made of high-quality materials and adheres to strict manufacturing guidelines. There are three rows of 15 pins on the gold-plated connector.
What does the VGA connector resemble?
A VGA connector is depicted in the following images. Because of the pins, they’re easy to spot:
Receptacle for females
Because there are two types of VGA connectors, it’s critical to know which one you need before obtaining a cable. This is how they differ: male and female plugs or cables are classified according to the gender of their pins. Males have pins on both sides, however females only have one row of 15 pins, so don’t get them mixed up! The size difference between male and female plugs is another feature that distinguishes them. Male plugs are larger than female plugs. Finally, many individuals who don’t know what they’re looking at may mistake an HDMI cable for a VGA cable, despite the fact that the two are completely incompatible.
What Is the Purpose of a VGA Connection?
A VGA connection uses analogue signals to transmit video signals. This implies that a video will be viewed on your computer exactly as it was transmitted. This is accomplished by sending whatever you want to see through copper wires, which are often made of metal (silver or gold) and connected at both ends by the three rows of pins explained earlier.
One of the advantages of using VGA connections for all of our digital gadgets, including computers and televisions, is that they are quite inexpensive, so anyone can afford one! They’re just about $35, whereas HDMI ones are closer to $100, so if price is more important than performance, go with the less expensive alternative.
VGA cables are still utilized in many devices today, so there’s no need to worry about them not being compatible with the latest technology. Plus, there are ways to connect a modern device, such as an HDMI cable, to your computer monitor or TV without causing any issues, so don’t worry! (I’ll go into more detail about this later…)
Are VGA Cables Going Out of Style?
VGA cables have become outdated as a result of the advent of HDMI, and properly so. The issue is that HDMI connectors can only be used on newer devices like TVs and monitors, however most computers still use the older connector type for video output, which means you’ll need a VGA cable to connect your computer display or TV if it doesn’t have an HDMI port!
When both VGA and HDMI are available, which should you use?
If you’re doing everyday computer work and don’t require fancy graphics or to accomplish anything too demanding, VGA connections are usually suitable for most devices.
When you require a higher-quality signal and want your computer monitor or TV screen to be as sharp, clear, and high-resolution as possible without any interference, HDMI cables are the way to go. If HDMI isn’t accessible on the device that requires it, VGA is a viable alternative that should suffice in most circumstances.

Is it possible to convert VGA to HDMI?
You can convert VGA cords to HDMI cables, which is the answer to this query. The procedure necessitates an adapter with a female connector on one side and a male counterpart on the other, so be sure they’re not mixed up! You’ll also need some extra equipment, such as a cable with male or female connectors on both ends, depending on which end needs to be converted, and then follow these steps:
To begin, connect your new device (TV) to the converter by either plugging it into the TV’s port or attaching it to any open ports head first. Then see if any further adapters are required for converting from Vga/HDMI, as they may be required in some circumstances.
VGA Technical Specifications
So now we get to the nerdy part. The acronyms and numbers after that represent the VGA cable standard specifications.
The following are the standard graphical modes:
640 x 480 pixels, 16 colors
640×350 pixels, 16 colors
320×200 pixels, 16 colors
320×200 pixels, 256 colors (Mode 13h)
The following are the VGA specifications:
Video RAM: 256 KB (Some video modes were lost when the first cards were ordered with 64 KB or 128 KB of RAM.)
16-color and 256-color modes are available.
Color palette with 262,144 values (six bits each for red, green, and blue)
Master clocks of 25.175 MHz or 28.322 MHz are selectable.
A maximum of 800 horizontal pixels is allowed.
A maximum of 600 lines is allowed.
Refresh rates of up to 70 Hz are possible.
Interrupt vertical blanking (This isn’t supported by all clone cards.)
Up to 16 colors in planar mode (4-bit planes)
256 colors in packed-pixel mode (Mode 13h)
Support for smooth scrolling in hardware
There are no hardware sprites.
There is no blitter, but the ‘VGA latch’ registers allow for extremely fast data transfers.
Some “Raster Ops” are in favor of it.
Shifter for barrels
Support for split-screen
Peak-to-peak voltage of 0.7 V
Double-terminated impedance of 75 ohm (18.7 mA – 13 mW)
Ugh, this was a challenge… Of course, if you’re not a techie, these values may be meaningless to you, but they’re here for those of you who want a more particular explanation.
Mini-VGA vs. VGA
Because there was less room for connectors on slimmer computers, they had to be smaller and narrower. Mini-VGA ports are common on netbooks, tablets, and other slim-profile devices; nevertheless, if you’re not sure which sort of port your laptop has, check the packaging or manuals.
The fundamental difference between these two types of cables is that VGA cables have a larger connection tip (up to 12 mm in diameter), whereas mini-VGA cables are similar in size to HDMI cables (- just over an inch).
Mini-VGA to VGA adapters are also available, allowing a conventional VGA display device to be connected to a computer with a mini-VGA port.
Is VGA capable of carrying audio?
No, audio cannot be carried through VGA cables. To connect your speakers or headphones to the device from which you wish to output sound, you’ll need a different cable (e.g.: laptop).
To connect your speaker system with a VGA connector into the port of either your PC or laptop, you’ll need a cable, just like other PC ports. It would be ideal if you had a separate audio port and sound card for the display to deliver sound, however since most HDMI TVs are HDTVs these days, most HDMI TVs come with built-in speakers.
VGA is a computer format in which practically every function is handled by a separate device, such as displays, keyboards, mice (computer mice), and audio speakers.
Both the signal source (video card, integrated chip, etc.) and the quality of the VGA cable have a resolution limitation with VGA. VGA has a maximum resolution of 20481536 pixels, however manufacturers may vary. The maximum resolution for VGA on contemporary graphics cards is 20481536, but this varies from manufacturer to manufacturer.

If you spend any time at all on the Web, you’ve probably heard of VGA , the video graphics adapter. If you’re not an IT-type, VGA is the big three-pronged connector that plugs into a monitor, TV, or projector to allow a video signal to be sent to a monitor or TV. VGA is definitely not a sexy term..
