D-sub vs. DVI

D-sub is the oldest device that is valid for computer connectors. On the other hand, DVI is an advanced technology suitable for video displays. Let us discuss the main differences between D-sub and DVI in detail.

Major Differences

D-sub and DVI are two connectors that are widely used all over the world. The primary function of D-sub and DVI is to transmit the signals. The signals may be digital or may be analog. Moreover, these devices are more capable than the other connectors.

What is D-sub?

D-sub is an advanced connector device widely used for transmitting signals. It can send analog signals. Moreover, it is available in all sizes and has numerous pin counts. D-sub is valid for the computer connectors.

Furthermore, D-sub mainly performs for the highest using connector that uses DE9 for devices. Also, DVI can make a connection with D-sub. Lastly, the D-sub plug is also used in electronic accessories such as printers and PC. It is the more versatile plug or connector.

Features and uses

  • Widely using in the world
  • Advanced connector for transmitting the signals
  • Use in many electronic devices
  • More versatile
  • Protects the connectors from interferences

What is DVI?

DVI is an old device known as a connector or display. The primary function of DVI is to transmit signals. It conveys both types of signs. It includes digital signals and analog signals. Moreover, these devices are capable of all electronic devices such as PC, printers, LED and LCD, refrigerators, laptops, and much more.

Furthermore, the complete form of DVI is Digital Visual Interface. It is more versatile as compared to other connectors. Three sizes of DVI have been introduced, named DVI-A, DVI-D, and DVI-I.when it gives signals to video displays, it shows higher-resolution pictures to the viewers.

Features and uses

  • Use for visual displaying
  • It has three types
  • Available in 3 standard sizes
  • Transmit both digital and analog signals
  • It provides higher-resolution power

Key Differences between D-sub and DVI

  1. D-sub transmits only analog signals. On the other hand, DVI transmits both analog and digital signals.
  2. D-sub is the most advanced connector as compared to DVI.
  3. DVI was introduced in 1999, whereas D-sub was introduced in 1957.
  4. D-sub is the most outdated plug in contrast to DVI.
  5. DVI has three sizes, while D-sub has five sizes.
  6. DVI is available in three types, while D-sub has many configurations.
  7. DVI is mainly used for visual displaying. On the other hand, D-sub is used in mice, printers, and PCs.

Comparison table between D-sub and DVI

Features D-sub DVI
Transmission Transmit analog and digital signals Transmit analog signals
