Home Theater, DVI Cable Information and Aid
By Dustin Twiggs

So What is DVI? DVI Stands for Digital Visual Interface. DVI is the digital interface standard produced by the DDWG (Digital Show Working Group). Led by Compaq, Fujitsu, Silicon Image, Hewlette Packard, NEC, Intel and IBM, the DDWG’s foremost objective is to “take up the industry’s equipment for a digital connectivity specification for high-performance PCs and digital displays.”

With the need to accommodate both digital and analog monitors, this new digital interface standard was produced to chat analog signals into digital signals. DVI’s High bandwidth capabilities make it ideal for HDTV connections. Also available in dual link, DVI can get to privileged resolutions still.

Using the pictures on the right, you can determine the category of connection you need, be it DVI-D, or DVI-I. To determine the real signal being ancient you will have to consult your manual for the contrivance being together. For more information concerning DVI:

DVI-D Digital. Connectors on DVI-D do not have the 4 additional pins, these are meant for carrying Digital signals single. Digital must be together to Digital and Analog to Analog. Even as you can plug a DVI-D cable into a DVI-I socket, both devices you are connecting must support Digital signal format. Analog to Digital will not work.

DVI-I Analog or Digital. Connectors are basically the same as DVI-D with the exception of 4 added pins. You’ll notice both have 3 rows of pins to the left, and one horizontal pin to the right. The DVI-I connection has 4 additional pins, 2 on top and 2 on underneath. These pins are ancient to carry the needed signals for RGBHV analog video. (Red, Conservational, Blue and Horizontal). You can use DVI-I on both DVI-D and Analog connections, but remember, an analog contrivance will not be compatible with a Digital contrivance. For more pictures of these bits and pieces stay:

Adapters HD15 to DVI-I (VGA to analog) adapters exist to join your analog contrivance to a analog show owing to DVI connection.

Remember that even as DVI-I is usable for Digital show, the extra 4 pins make it usable for Analog as well. The needed adapters is available in our store.

How To Tell Which DVI Cable You Need
By Neil MacLeod Platinum Quality Author

DVI-D cables also know as right digital video cables and are ancient for a right digital connection between two electronic components (normally a video card and an LCD mind). All video cards ever produced have always been able to make a digital output, the single downside before DVI came in this vicinity was that this output had to be downgraded to analog before being sent to the mind – where it was then converted back to digital by the mind! Using a DVI-D cable earnings this administer isn’t required and therefore the end result is a very quick and extremely high quality visual output.

DVI-A cables also known as high resolution analog cables and are ancient to transmit a DVI signal to an analog show unit (normally a CRT mind and becoming more ancient on HD televisions). Although this category of output isn’t as excellent as DVI-D (due to the failure of data in the digital to analog conversion processes), it still gives a much improved output than the show from a standard VGA output.

DVI-I cables are capable of transmitting between two devices in either a digital to digital format or an analog to analog format, but (and that’s a huge BUT) it will not join two dissimilar devices (i.e. digital to analog or analog to digital).

Note: DVI digital and DVI analog formats are not identical, basically this earnings that a DVI-A cable will not work on a digital system and a DVI-D cable will not work on an analog system. You must know before purchasing a DVI cable what format your two devices are, remember that single gear with a DVI port labeled DVI-I will accept both a DVI-A and DVI-D signal.

So how can you tell what category of DVI cable you currently have? The simplest way is to read the manual for the devices you are connecting, or by looking at the DVI cable. There are two traditions to determine what DVI format a contrivance is by looking at the end of the DVI cable face on: 1. There is always a flat pin on one side of the DVI cable, a flat pin alone denotes a DVI-D connector and a flat pin with four surrounding pins can be either a DVI-I or DVI-A connector. 2. The pins on the DVI cable denote whether the cable is single or dual link, 24 pins in 3 rows of 8 earnings it’s a DVI dual cable, even as two lots of 9 pins with a gap in the middle earnings you have a DVI single link cable. Note: To work out if a cable is DVI-I or DVI-A you need to look at the digit of pins on the DVI cable end, 24 pins earnings you have a DVI-I cable and a set of 8 pins with a gap to a set of 4 pins denotes a DVI-A cable.
