DVI To HDMI - Everything you Need To Know About DVI - Part 1

In the last discussion we discussed briefly about DVI to HDMI intro and also briefly about DVI and HDMI. This post will be solely dedicated to discuss about DVI (we'll discuss dvi to hdmi very soon).

DVI is an abbreviation for Digital Video Interface.

DVI is used along with the flat LCD panels and monitors coupled with the latest graphics card to provide best of the video quality. And DVI acts as an interface to carry this high quality information. This came to an extent of replacing p&d plug and display standard. Graphics card manufacturers love DVI ports & also dvi to hdmi too, because they can output high quality video through the video cards. Thus most of the graphics card manufacturers provide a port for the DVI output, through which you can connect a cable to your display device and see the game or graphics application running.

Because of the success and quality of dvi output, many of the dvd player manufacturers started adopting the dvi output and many dvd players have an option for the dvi output. Even HDTVs used dvi as a means of information broadcast to telecast tv shows and movies. But recently TVs have shifted towards the HDMI and the computer industry still hugs the DVI, and thus dvi to hdmi is more of a fusion of both of these platforms.

DVI to HDMI : Types of DVI connections

Let us discuss something more about various types of dvi connections that are available. Presently there are 3 types of dvi connections that are available, namely, DVI-Digital, DVI-Analog, and DVI-Integrated. We'll discuss briefly about all three of these.

DVI-D cables are used to interconnect the LCD monitors and the source of the video like video cards, and this is a digital connection. Because the format of transmission is digital, it ensure a higher quality of image and is faster. Usually most of the video cards output in VGA, which needs to be converted to a digital format in order to be used for DVI, but using DVI-D this can be easily avoided and the conversion can be skipped. We'll discuss about how these can be used for dvi to hdmi.

DVI-A are the medium to transport signal to an analog display device such as a CRT monitor or may be a budget LCD display. Use of DVI-A can be found more in the place where signal needs to be taken to a VGA device, and in this case there is always a loss of quality. These can't be used for dvi to hdmi as there is loss of quality. This loss of quality is not because the video information is produced that way, but because of the conversion that takes place.

DVI-I cables are a combo type of cables which can do both the tasks performed by the above cables. These cables can either transmit an analog-to analog signal, or a digital to digital signal. Thus this cable can be used at multiple places and purposes as there is no bound for to be used for digital or analog. This can be used for dvi to hdmi conversion purposes.

There are few more things that you need to know about DVI itself before we jump on to discuss dvi to hdmi, thus we'll cover it in the next post.
