6 Difference between DVI and D-Sub (With Table)

Since the emergence of technology, a lot of improvement has been taking place in this field. Many people are moving from analog life to digital life hence a lot is being invented.

Many people prefer to have videos of the many occasions they are attending. Some are wedding occasions, funerals, music recordings, and many more.

DVI and D-Sub are two major jargons of higher resolution video output. They are similar in their appearance and to some extent their names. This makes a lot of people refer to them interchangeably.

So, what is the main difference between DVI and D-Sub? DVI is designed to transmit both analog and digital signals while D-Sub is only designed to transmit analog signals.

For more information about the difference between DVI and D-Sub in tabular form, continue reading the article. You will also get to learn of the similarities between the two.

Comparison Table (DVI vs D-Sub)

Basic Terms DVI D-Sub
Transmission of signals It transmits both analog and digital signals. It only transmits analog signals.
Video quality The videos are of high quality. The videos are of comparatively low quality.
Invention It was invented in 1999and is still very much in use. It was invented in 1957 but it is outdated.
Types They are of three types; DVI-A, DVI-D, and DVI-I. It has a wide variety of shell sizes.
Uses It is only used for video display. It is used for a number of purposes such as VGA, serial port, parallel port, and mouses.
Connector It is a standard connector for video display. It was a standard connector for computers.

What is DVI?

DVI was invented in 1999 for commercial use. It was made specifically for supporting higher resolution video displays.

It is designed to transmit both analog and digital signals. The videos displayed using DVI are of high quality and clearer.

They are of three types, they include; DVI-A which only transmits analog signals, DVI-D which transmits only digital signals and DVI-I which transmits both analog and digital signals.

The ones mostly used are DVI-D and DVI-I as they are able to transmit digital signals. DVI-I is used for connecting input and output devices with both plug-in types.

DVI is a cable that is used for computers and laptops. It also uses pins to connect to the channel which forms the basis for the confusion of DVI and VGA cables.

What is D-Sub?

D-Sub was invented earlier in 1957. It was designed to transmit analog signals only. This has led to it being outdated hence not commonly used nowadays.

It is also known as VGA as it transmits video signals. VGA only uses analog signals. It has various uses such as mice, parallel port, serial port, gaming pad. They have been replaced by USB cables.

The D-Sub still used is the DB9 and DB15 connectors for monitors. They have a strong build and can screen against electromagnetic radiation.

They have D-structure which enhances support and correct orientation to the cable and a metal shield that provides protection from radiation.

The video output from D-Sub is of low quality and not clearer as compared to DVI video output. This makes most people prefer DVI.

Similarities between DVI and D-Sub

  1. They are both used for video display.
  2. Both can transmit analog signals.

Conclusion

DVI and D-Sub are both used for displaying videos. D-Sub was invented earlier than DVI and hence not able to transmit digital signals.

DVI is widely used nowadays as it is able to transmit both analog and digital signals, unlike D-Sub which is not commonly used nowadays as it is considered outdated.

The main difference between DVI and D-Sub is that DVI is able to transmit both analog and digital signals while D-Sub is only able to transmit analog signals.
