Has it been challenging to establish a good connection to a computer to a television, monitor or any device for display with their own built-in audio system using a DVI? Perhaps it has left you wondering if the DVI cable also supports the audio? You’d be glad to know if it does because at least you won’t have to worry about needing another wire to make the audio work.

Different interfaces require varying specifications concerning technicality. Many of them transmit both video and audio while others only transmit videos. Perhaps the only question left to answer is this: does DVI carry audio and video too?

DVI: An Introduction

The Digital Display Working Group (DDWG) created and powered this tool in 1999, the Digital Visual Interface, also known as the DVI is a digital interface used to transmit data from a video in a computer to a particular display device.

Before the invention of such a device, videos were often transmitted through VGA ports. When the interface of the DVI was introduced in the picture, they helped standardize the method of transferring videos from computer installations, allowing users to enjoy high-quality video productions.

DVI cables are longer than the ones used for the VGA and still be able to produce video images at a 1200 x 1920 resolution. The cable can be 15 feet long, though a repeater is often used to support the transfer while minimizing the possible signal degradation. It is for these that the DVI was considered somewhat like a successor, though unofficial, to those who first used the VGA.

Kinds of DVI cables

Because every person needs a particular DVI cable for a specific use, the people behind it made sure that everyone is able to get hold of a cable that fits perfectly. Every type of DVI cable serves a particular purpose. It is not that one is better than the other because they are all ready for the market and perform their function. However, the type of cable that people use speaks a lot of their need for it.

  • DVI-I

It is the type of cable that is perfect for reading both digital and analog signals. If the goal is to transfer old videos and prepare them for the new interface of digital players, then this might be the perfect cable to use. It allows the user to read both analog and digital signals which means an old video can be transferred properly without worrying about losing data in the process.

  • DVI-D

This is a common type of DVI cable used. Although it is possible for a DVI cable to help transmit both audio and video, they need a little tweaking done. Everyone chooses this type of DVI cable particularly because it appeals to modern users whose digital signal is strong. It also comes in a length that is favorable for those who are multitasking. It stretches far in a given space without disrupting the transfer of the video file nor does it cause any problem in its quality.

  • DVI-A

The name itself suggests that it is the type of DVI cable that reads analog signals only. This may seem a bit old school to many because who isn’t in the digital world, but it is found useful by many users. It is able to draw a connection between the old video source to a new one and that makes all the difference. The best videos, after all, are made when one is carefree and didn’t think much about technology.

Whatever you decide to use among these three options, it is important that you understand that no DVI wire will be able to transmit the audio, unless one becomes creative and does a little change…

How is audio transferred using the DVI device?

Is it possible for a DVI user to be able to transfer both the video and the audio? If you wish to make a successful transfer of both files, then you will have to use a special HDMI-to-DVI cable. This is assuming that the computer unit you’re using supports an HDMI audio through DVI. The special cable will help transfer both the video and its audio as one single file. Perhaps the only good news in what seems like a complication in DVI cables is the fact that most computers support this particular feature.

If you are still using an old video card, you might need to have it upgraded to be able to make use of this special cable. There is no need to fret that an upgrade might cause you to lose your files. In any case, it might be best to prepare a back-up file before the video card is updated.

Compared to its DVI counterpart, the HDMI (High-Definition Multimedia Interface) is able to support both audio and video files. Although the HDMI has become the preferred interface to use particularly because it supports both the audio and the video, those who continue to use the DVI are happy to be able to do both in a rather challenging process.

The DVI-to-HDMI cable allows its end users to transfer the video file from DVI format to the HDMI port. It is fairly easy to go for the HDMI option and choose to transmit both the audio and video file. However, if the end-user wants to transmit audio over a DVI device, it is best to check if such a feature is supported by your computer system.

You might need to install the latest driver. If it works, then it is best to go for the DVI-HDMI cable to be able to connect two important devices. Aside from the HDMI-to-DVI adapter with audio out, you may need to use two cables to make the video and audio transfer using the DVI. For instance, you may need to use both the traditional DVI cable to be able to transmit the video and another analog audio cable to be able to transmit the audio.

Such an option may not be the most ideal, but it will work. Being that all the devices that are DVI may some home need support of another cable, it does not mean that it cannot do the job. The support it is getting will only make the output and transfer correctly. If one wants to make a transfer of a video file using a DVI, it is best to get the DVI-to-HDMI cable option. It is the best the market has to offer at the moment.

Does DVI support audio?

The answer to this question may not be the most ideal, but some little tweaking can be done to make it happen. The DVI cable may need help, but it only means that it is doing its best to make both the audio and the video available to the consumers.
