DVI-I vs. DVI-D | Which Connection Provides Higher Sign and Greater Decision?

DVI, the quick kind for Digital Visible Interface, is a video interface designed for greater resolutions transmission in LCD screens, video graphics playing cards, and projectors. It was superior by the Digital Show Working Group (DDWG). The video interface transmits uncompressed digital video indicators to a secondary show gadget from a supply gadget. It’s widespread in video playing cards and will have one or two.

DVI has three codecs; DVI-D, DVI-I, and DVI-A. DVI-D transmits solely digital indicators. DVI-A transmits analog indicators solely, whereas DVI-I transmits analog and digital indicators. When related with DVI-D, DVI is suitable with HDMI, which accepts the digital sign. It’s also suitable with a VGA connector utilizing DVI-A that transmits analog indicators.

The 2 DVI codecs, DVI-D and DVI-I, have a number of similarities, though they differ in some ways. Learn via to study extra about DVI-I vs. DVI-D.

DVI-I vs. DVI-D Similarities

In some ways, the 2 DVI codecs are very comparable. To start, each can transmit digital video indicators, with the exception that solely the DVI-I can even ship out analog video indicators. Video indicators are one other commonality between the 2 units. They’re unable to ship or obtain audio information. One other comparable function is that DVI-D and DVI-I are coloured white incompatible units. Most suitable units have DVI-D and DVI-I ports coloured white. Additionally, each of them have a single hyperlink and twin hyperlink assist.

DVI-I vs. DVI-D Variations

Regardless of DVI-D and DVI-I having a number of comparable options, they differ in some ways. Firstly, a DVI-D connector is a male connector, whereas a DVI-I is a feminine connector. This function implies that DVI-I can assist all different DVI video interface codecs, whereas DVI-D can’t assist different kinds.

Secondly is the variety of pins. DVI-I has 23 pins (single hyperlink), whereas the dual-link connector has 29 pins. Then again, the DVI-D video interface has 19 pins for single hyperlink connectors and 25 for dual-link connectors. The only-link DVI connector permits transmission of 1920 x 1200 show decision at 60 Hertz refresh price, whereas a dual-link DVI will transmit 2560 x 1600 show decision at 60 Hertz refresh price.

A DVI-D video interface solely transmits digital video indicators, whereas a DVI-I video interface transmits each analog and digital video indicators. This function implies that the DVI-I’ll have broad compatibility and applicability with a DVI-D connector. Notice that the DVI-I connector doesn’t convert analog indicators to digital or digital indicators to analog. Nevertheless, they settle for the indicators however cannot settle for each concurrently.

HDMI port with the cable inside

The following distinction arises from compatibility. A DVI-D connector is suitable with DVI-D and DVI-I connectors. This video interface can be suitable with HDMI and DisplayPort connectivities via applicable adapters. Nevertheless, this connection can’t assist audio transmission and CEC controls. Then again, a DVI-I connector is suitable with all three DVI codecs. The one drawback arises when connecting a male DVI-I cable with a feminine DVI-D connector. It will not work because the DVI-1 connector has 23 pins whereas the DVI-D pin has 19 pins.

Subsequent is the structure. DVI-I connector has a wider lengthy flat pin than that of the DVI-D video interface. This function implies that eradicating the 4 further pins from the feminine DVI-D video interface cannot be suitable with the male DVI-I video interface. Nevertheless, you possibly can effortlessly join a male DVI-D video interface to a feminine DVI-I video interface. That explains why most fashionable units, particularly flat-panel LCD screens, have DVI-D enter ports.

Is a Single-Hyperlink DVI-D and DVI-I Suitable With Twin-Hyperlink DVI Connectors?

Twin-link DVI-I and DVI-D connectors are suitable with single-link DVI connectors. Meaning a dual-link DVI-I can be utilized as an alternative of a single-link DVI-I connector. Nevertheless, a single-link DVI connector, each DVI-I and DVI-D, cannot be used rather than a dual-link DVI connector. In the identical case, a DVI-I video interface can be utilized rather than a DVI-D video interface, however a DVI-D video interface can’t be used rather than a DVI-I connector.

Making use of the dual-link DVI-D or DVI-I video interface rather than a single-link DVI implies that it’s profitable, though the connection could also be restricted by the variety of pins on the feminine DVI connector.

Single link DVI D

Which Is Higher, DVI-I or DVI-D?

It’s upon one’s option to determine which DVI video interface to make use of. You have to perceive the distinctive options, performance, and advantages of the completely different DVI connectors earlier than deciding on the one to make use of for a selected use. Nevertheless, you might wish to know the commonest or most well-liked one on most units; here’s a lead.

Regardless of the DVI-I connector being extra versatile than the DVI-D connector, it’s much less most well-liked on most fashionable units. The DVI-D is broadly utilized in motherboards and graphics playing cards. These DVI connectors assist customers join their private computer systems with digital screens. Equally, they let you join your private pc with a CRT monitor.

Can You Make a DVI-I Right into a DVI-D?

Whereas most customers will break the 4 analog pins on the DVI-I connector to make a DVI-D connector, that is not at all times the case. To begin with, you may find yourself ruining the DVI-I video interface, which you may want sooner or later. Secondly, there is perhaps some bits of the pins remaining on the DVI-I connector, which can trigger the connector to not match accurately.

Typically, although, this try cannot utterly work. A DVI-I to VGA connection can work as a result of the DVI-I connector transmits an analog sign. VGA customary interface additionally transmits analog indicators; therefore the dialog could also be profitable. Nevertheless, the DVI-D connector doesn’t carry analog indicators and may have a converter to transform the analog indicators from the DVI-I connector.

Single link DVI D

Is DVI-I Connector Nonetheless Used?

DVI connectors are slowly vanishing from the digital world and being changed by superior expertise customary interfaces, significantly the DVI-A and DVI-I connectors. These DVI connectors carry analog indicators, that are out of date on most fashionable units utilizing digital indicators with excessive show resolutions.

Nevertheless, some units, particularly 1080p screens, nonetheless have DVI-D enter ports. These screens are suitable with DVI-D transmitting 1080 pixels show decision at both 60 Hertz or 144 Hertz refresh price. Moreover, DVI cables are low cost and generally out there.

What Is the DVI-D Connector Port For?

The DVI-D port discovered on most screens, projectors, and different electrical units connects to the PC or different supply units utilizing the DVI-D cable. This port permits the transmission of digital indicators solely. 


It solely transmits video indicators. It’s generally used to attach the monitor to the DVI playing cards. You will discover it in dual-link or single hyperlink. The twin-link DVI-D connector has sooner information switch charges and better show resolutions than single-link DVI-D connectors.


DVI video interface transmits video indicators solely. The DVI-D and DVI-I connectors are comparable in a number of elements however differ in lots of options and functionalities. The variety of pins on these connectors, the character of indicators transmitted, versatility, and compatibility vary. Regardless of the DVI connector slowly turning into extinct, you are extra more likely to discover a DVI-D port on a monitor or a projector than a DVI-I connector.
