What Is The Difference Between DVI-I And DVI-D?

DVI-I and DVI-D are connectors that can send out a digital signal and an analog signal. DVI-I supports digital and analog signals, while DVI-D provides a digital-only signal. You cannot plug a DVI-I cable into a DVI-D monitor because the line would not fit in the connector.

DVI-D cable is the most popular type of connector that transfers digital signals only. DVI-I is a connection or interface that has used between monitors and computers. You can also use this DVI-I connection in home theater systems.

Most video cards have DVI-I connectors because they support both analog and digital video. On the other hand, some video cards have DIV-D connectors that mean you cannot use a DVI-I cable. You can continue to read more about these connectors!

DVI-I

DVI-I stands for Digital Video Interface connectors for connecting a digital flat panel. You can connect it to your LCD monitors and projector to the card. DVI-I connectors are available in white color as opposed to a VGA connector which is colored blue.

DVI-I sends digital signals for digital displays such as LED-backlit LCD monitors. DVI-I also sends analog signals for older shows such as CRT monitors using a DVI to VGA adapter.

DVI-I connectors have 23 pins (18+5), and dual-link connectors have 29 pins (24+5). These connectors accept digital and analog signals, and that cable is compatibles with digital and analog equipment. It cannot convert pure DVI-D output to analog.

DVI-D

DVI-D stands for Digital Visual Interface. This cable connects a video signal from a computer to an LCD monitor, and it carries a high-quality analog signal. The DVI-D is the most popular type of connector for hooking up DVI cards to LCD monitors.

A DVI-D connector on a graphic card sends out a digital signal as flat penal. This connector has 19 pins (18+1), and the dual-link DVI-D connector has 25 pins (24+1). DVI-D connectors cannot support the additional features that a display port possesses.

Most digital monitors have DVI-D connectors, while monitors support both digital and analog signals. DVI-D offers more power and a faster data transfer rate than the single-link format.   

  • Types of DVI-D

There are two types of DVI-D connectors.

  1. Single link: A single link of DVI-D uses three rows of six pins that do not have contacts like what you had seen with a DVI-I single link connector.
  2. Dual-link: The dual-link of DVI-D has three rows of eight pins to complete dual-link connections, and it does not have contacts.

Difference between DVI-I and DVI-D

Every graphics card and motherboard has DVI-I connectors. There are many pins, and layouts of the pins on the DVI connectors differ depending on their type. DVI-I connectors have more pins than DVI-D connectors.

In nowadays, the DVI-I is the most versatile connector. You can use it with HDMI, VGA, and display port devices by using proper adapters.

  • The signal capability between DVI-I and DVI-D

DVI-D connectors carry only digital signals, while DVI-I connectors carry both digital and analog signals. If you have an old monitor, you will never need analog capabilities. So, DVI-D connectors are the only kind modern gamers need.

DVI-I allows a higher bandwidth when its connectors utilize all 24 pins. It also supports a screen resolution up to 2560*1600 at 60Hz or 1920*1080 at 144Hz.

  • Video quality

DVI-I and DVI-D have good video quality. Both connectors can transmit more explicit and higher-resolution videos than other connectors. DVI-I connectors have more pins and allow for a faster refresh rate, and it does not support audio.

  • Digital connection

DVI-I cable does not fit in the connectors because you cannot plug a DVI-I cable into a DVI-D monitor. Most video cards have CVI-I connectors because these cards support both analog and digital video. But some video cards have DVI-D connectors that mean you cannot use a DVI-I cable.

Which is best?

DVI-D is the most style that is why all DVI-capable devices on the market use a DVI-D interface. DVI-I analog-only cables are rare, and their analog devices are non-existent.  

DVI-D only transports digital signals over the DVI-I cable because DVI-I transports digital and analog. DVI-I is primarily helpful if you are trying to connect to a VGA- only printer using a DVI-I adapter.

When we determine the best picture quality and versatility, a DVI-I cable is best. It allows the flexibility you need whether you are streaming from an analog. DVI-I supports dual-link, and there is probably no disadvantage compared to DVI-D.  DVI-I connectors offer the most flexibility; video cards such as the ATI Radeon 8500 use these connectors to connect a DVI digital screen or a VGA monitor.

You can watch a video on YouTube to know which connector is best. The link has given below:

Conclusion

DVI-I and DVI-D both connectors offer distinctly sharper and better pictures than other connectors. Both are unique connectors because both are carry digital and analog signals. They are converted easily to different standards like HDMI and VGA.

DVI-I connectors can only transmit analog. You can use double link connectors to increase data transfer speed, but you will require two cables for this process.
