DVI vs. VGA | Core Differences Explained With Table for Understanding

Now we will discuss different types of connectors in this article, the DVI connector and the VGA connector. Both of these connectors will use to connect computer monitors to computers, although, some things make both connectors different from each other. The DVI connector is newer than the VGA connector, and the DVI has the qualities of becoming more advance than VGA. Learn DVI vs. VGA.

You can get the advantages of both of these connectors and look at why you would use one over the other. Whether you need to set up a digital video projector or a video arcade, you know the importance of using a VGA cable. Learn more about how they differ from DVI cables. Plus, a whole lot more to come!

What Is A DVI Cable?


A DVI cable, or Digital Video Interface cable, came into existence following the establishment of HDMI and is the more recent version of the “Digital” video cable. The critical difference is that DVI cables can transmit sound and video signals, unlike HDMI cables. DVI cables can transmit digital audio and video signals over a single line. Three cables transmit digital video signals as per the digital video interface cable. 

Types of DVI Cables


These are DVI-DVI, DVI-A, and DVI-I. DVI-DVI is the digital video cable used for transmitting digital video signals from one digital video interface port to another. DVI-A is use for sending video and audio signals from one digital interface port to another analog device. It is very beneficial to connect your computer to a VGA monitor. DVI-I features both digital and analog ports. Further, both audio and video signals can transmit to a monitor or a TV.

What Is A VGA Cable?

What Is A VGA Cable

First, connect the VGA cable with a monitor to your computer if you want to use it. After that, you can use any VGA cable. The VGA cable is a specific type of video cable. It has 15-pin D-sub connectors on both ends. The line itself is color-coded to represent the various connectors. Red, green, blue, and white (RGB) wires represent the pixels on the screen. 

The VGA cable can only display a maximum resolution of 1280 x 1024. Also, the VGA cable is analog, which means the image quality is not as straightforward as possible. Newer systems use digital monitor cables called DVI. If you need to present high-resolution images or movies, you need a DVI cable.

Differences between DVI and VGA

Differences between DVI and VGA

DVI and VGA are two very similar connections for computer monitors, but there are a few differences between the two. One difference is that DVI can support up to 1920×1200 resolutions, while VGA can only support up to 1600×1200 resolutions. The other difference is that DVI has a male connector on both ends, but VGA only has a male connector on one end. DVI and VGA are both analog interfaces for computers.

DVI displays are newer and more versatile than VGA displays. While VGA sends the information in analog format, DVI sends it digitally, making it more efficient and less prone to interference. DVI displays are easier to use with multiple monitors, are more versatile, and display a broader range of colors.

VGA is older technology, so most new computers don’t have a VGA port. However, VGA is still viable if you need a display to hook up an older computer or home theater system.

Why Is A DVI Cable Better Than A VGA Cable?

Why Is A DVI Cable Better Than A VGA Cable

Among the various cables made to connect computing devices, the VGA cable is most common and is easily identifiable by its 15-pin female end. These cables use for connecting computer monitors and computers. Present-day computers have graphics cards that have a DVI output.

These graphics cards make use of a DVI cable. The VGA cable cannot communicate with the new graphics cards in computers. As a result, a DVI cable is essential when connecting a computer to a monitor with a DVI input.

How can you tell what kind of DVI or VGA ports you have?

How can you tell what kind of DVI or VGA ports you have

It is pretty simple. You don’t need any special equipment, only a pen or a pencil/marker. The main thing you must determine is if you have a DVI or a VGA-I connector. DVI stands for Digital Visual Interface, while VGA-I stands for Video Graphics Array-Integrated. Connect the monitor and turn on the PC to determine which one you have, note where the display shows a picture. There should be a display on the monitor. If there’s a white paper in the center, you have a VGA-I. If there’s a black display with white letters, you have a DVI.

Risks of Using VGA

Risks of Using VGA
  • Risk of using VGA is that it is incompatible with other standards and technologies, and most devices have abandoned it.
  • VGA is an analog, low resolution, text-oriented interface mainly used for CRT monitors.
  • VGA is not compatible with a digital monitor or laptop.
  • It allows remote access to the computer’s features and functions.
  • It transfers data and information between your computer and other devices.
  • It is a network connection. However, it is not secure enough to transfer confidential information.
  • VGA (Video Graphics Array) is the worst connection to use for a computer. Not only does it have high latency, but it also has an awful resolution and color quality.
  • VGA connections are commonly found on most old CRT monitors and have awful quality compared to DVI, HDMI, Display Port, and Thunderbolt connections.
  • VGA connections have a latency of about 16 milliseconds, which is much higher than most other connections.
  • VGA connections only support the RGB color palette, which results in an awful color quality in the image.
  • The VGA connections are commonly found on CRT monitors, typically 20 – 24 inches, and have a resolution of 800 by 600 pixels.
  • VGA connections are no longer used with modern computer setups and should not be used.

Advantages of VGA

Advantages of VGA

VGA cables are famous for carrying digital data, while DVI cables have analog data. VGA uses more in desktop computers that run on Windows, while DVI cable can use by devices like set-top boxes, DVD player, etc., which runs on digital media.

Partition of the picture when a digital photo sends using a VGA cable, the data can change into three, the first part understands as temporal, the second part is the picture quality, and the third part takes as the background. 

While this is not enough, the DVI cable has the picture data divided into two; the first part is the temporal data, while the second part is the quality data. The resulting picture of the first case will not be as clear as the second case, which uses a DVI cable. The image of the first case will be of low quality.

Who Would Use VGA, And Who Would Use DVI?

Who Would Use VGA, And Who Would Use DVI

VGA is older technology, still widely supported for backward compatibility. DVI is the latest and greatest and is NOT backward compatible. So, why would you use VGA? VGA cables are significantly cheaper and can build VGA interfaces into some PCs. 

DVI is the technology of the future, and it can provide you with the maximum display resolution; where VGA can support no more than 640 x 480, DVI can give you answers 1600 x 1200 to up, and in rare cases, 1920 x 1200. So, well, most not-so-technical computer users would use VGA. Most IT professionals and graphics professionals would use DVI.

Frequently Asked Questions

Which Connector Is More Relevant Today?

DVI (the more modern alternative for your HDTV)

Which Would You Choose?

  • VGA lets you get higher resolutions and a refresh rate of 85Hz. It’s more prevalent in businesses. 
  • DVI is great for playing video games. Most people do not use more VGA. They try to select it.

Which Connector Is Best VGA, Or DVI?

VGA! Digital always looks better.

Should I buy the new Apple display that only has an HDMI to DVI adapter (no VGA support), or should I stay with my VGA monitor

I’d go ahead and buy a new monitor that doesn’t have VGA support and use the HDMI to DVI adapter. 

Why Does VGA Still Exist?

  • VGA is still the most common monitor, so it’s the easiest to develop.
  • Too much money has been invested in training devs (writing white papers, presenting at universities) to replace it now


The days of the VGA cable are long gone. FOR MANY YEARS, the VGA (Video Graphics Array) cable was the standard for connecting computers to monitors. VGA cables use to connect Macs, PCs, and even some video game consoles to monitors. While VGA cables are still available, they are harder and harder to find, and they are not the standard anymore. 

If you are looking for a VGA cable to use with your computer, you can feel very hard-pressed to find one. VGA cables are incompatible with modern systems, so the reasons for using them have become obsolete.
