Difference Between DVI-I and DVI-D 

What is DVI?

First of all, what is DVI?

DVI stands for Digital Video Interface and is an graphical input used to connect your computer’s graphics card to your computer.

It’s but one of many connector cables (among VGA, HDMI, and DisplayPort) that is used.

You are able to quickly tell a DVI connector from others due to the white color of the plug (seen right) and the screws used to fasten them.

What types of DVI are there?

In total there are 3 different kinds of DVI inputs:

  • DVI-D (digital only signal)
  • DVI-I (incorporated, both analog and digital signals)
  • DVI-A (analog just signal)

In addition to this, there are two versions of DVI-D and DVI-I, a single-link version and a dual-link version.

Altogether there are five different DVI variations and the differences between each are illustrated below. The two DVI-D and DVI-I are usually being used, but use in DVI-A is remarkably rare.

Remember none of those DVI types carry sound. So it is not a fantastic cable if you are thinking about using it for built-in monitor speakers.


So what technically sets a DVI-D and DVI-I connector apart?

DVI-D and DVI-I differ physically from the number of hooks they utilize. This decides how much bandwidth they operate through their signs and what their type is.

As mentioned before, a DVI-D connection only has a digital signal whereas a DVI-I connection has both an analog and digital signal.

This is true regardless of whether they’re single or dual link.

Digital signals are utilized for contemporary monitors like digital displays while analog signals are used for older technologies like CRT monitors that are largely from use nowadays.

What is the difference between DVI Single Link and Dual Link cable?
The quantity of maximum bandwidth that it may use which dictates the maximum DVI resolution.

A single-link DVI-D or DVI-I cable may carry 3.96 Gbit/s and, because of this, is limited to a 1920 x 1200 resolution on a 60Hz screen.

A dual-link allows one to use a higher bandwidth because of the physical build and ups it into 7.92 Gbit/s, allowing you to use a maximum resolution of 2560 x 1600 at 60Hz. Even still DVI cannot do 4K.

The two DVI-D and DVI-I are getting more and more obsolete and should just be utilized in the unfortunate event that HDMI or even DisplayPort are unavailable. DVI just is not as great as HDMI or even DisplayPort which both offer superior picture quality and performance.
