What’s The Difference Between DVI-I And DVI-D?

When buying a computer, specifically the Dell computers, you would find that they have a Digital Video Interface or DVI connector for when you are connecting the unit to your LCD monitor to the graphics card of your system. However there are currently two available with the DVI-I and DVI-D, lets find out what’s the difference.

What’s The Difference Between DVI-I And DVI-D? The main difference between these two is that one provides a different signal than the other. The DVI-I would be more effective at supporting both digital and analog signals. However, the DVI-D is only great for supporting digital signals, which could limit you.

To help you better understand these two connectors, we need to break them down and look at some of these differences, especially when and how they would support certain elements of your display. In this article, we will look at both of these to find out how compatible they are and when you should use one or the other.

What’s The Difference Between DVI-I And DVI-D?

To help you understand the differences, we should look at what each of these systems support. Depending on the system you are using or the connection that you need, you will either use one or the other, but how do they differ from one another?


The DVI-D is the newer of the two interfaces and can be found on most modern computers. It can connect only to digital signals, which makes it effective for modern monitors and display systems. When connecting the cable, your DVI-D would only read the digital information, while disregarding the analog signals.

This also means that you can only use it on modern displays and some of the older displays, which still feature analog might not be as useful for you to use.


The DVI-I is a little more complex and it can send signals to both analog and digital displays. Instead of only working with modern LCD or LED monitors, it would allow you to connect to things like VGA and CRT monitors at the same time. 

The DVI-I connector also contains more pins than the DVI-D connector, which is due to the more complex nature of receiving various signals from different display setups. The motherboards and graphic cards, which contain the DVI-I connector are often fully compatible with some of the older and modern monitors and should give you the best of both worlds in terms of overall value and performance.


If you are only using modern systems, you might want to settle for the DVI-D. It would direct all the connecting capacity to deal with the digital signals of your display. However, those with various monitors, ranging from old to new should consider the DVI-I connector. Let us know in the comment section how these have affected your viewing experience.
