What is the Difference Between DVI-I and DVI-D?

Many would often use connectors such as DVI-D and DVI-I without knowing the real difference between the two. With that said, through this article, we shall provide you information that would show you the difference between DVI-D and DVI-I that will also help you determine how their purpose and how they work.

The difference between a DVI-D and DVI-I is that a DVI-D connector’s main purpose is to send out digital signal. A DVI-I, on the other hand, has the ability to send not only digital but also analog signal. Tough a DVI-D is compatible with a DVI-I connector, it will only be able to read the digital output and not the analog.

A DVI or Digital Video Interface on the other hand, is often found on most graphic cards and motherboards. It could connect a monitor and/or a projector to a computer. In most computers, a DVI connector is usually in white color while the VGA connector is often associated with color blue.

As mentioned earlier, a DVI connect could send out digital signal only and could not handle any analog signals which come from older displays. This is one of the reasons why a DVI-I connector would have more pins than DVI-D connector because a DVI-I could send not only digital but also analog signals.

Graphics cards and motherboards that has a DVI-I connector do not have any problems with connecting to flat-panel LCD monitors- which usually have DVI-D ports. The reason this is possible is because DVI-D will only read the digital output from the DVI-I connector and will set aside the analog signal.

Additional information, a DVI-A on the other hand could only handle an analog signal only.


The amount of pins and layout on DVI connector would depend on the type for graphics card or motherboard. DVI is known for its versatility. It could be used with different connections such HDMI, VGA and DisplayPort devices through the use of proper adapters.

Dual-Link connectors, on the other hand could use all 24 pins. This will allow higher bandwidth. Moreover, Dual-Link DVI also has the ability to deliver resolutions up to 2560×1600 at 60Hz or 1920 x 1080 at 144 Hz. Single-link DVI on the other hand could max out and could only handle up to 1920 x 1200 at 60Hz.


This concludes our article on what is the difference between DVI-D and DVI-I. To summarize it, DVI-D connector has the ability to send signals that are only digital while DVI-I connector on the other hand could send signals that are both digital and analog. Another additional information, a DVI-A connector could only send analog signals. DVI-D connector could still be able to work on DVI-I connector, however it will only use and read digital signal and would set aside and ignore any analog signal.

We hope that through this article, we were able to help you identify and determine the difference between DVI-D connector vs DVI-I connector vs DVI-A connector.
