DVI Cable Q&A

1) What is the difference between Dual Link and Single Link?
Dual link enables a higher resolution and three additional channels. Most users can substitue a Dual Link for a Single Link Cable.

2) I need a DVI-I to DVI-D cable - What part number do I buy?
You can purchase any DVI-D to DVI-D Cable as that is what you will be using.

3) Why are your DVI cables so inexpensive?
They are made offshore where labor is Inexpensive. We are the importer. We sell alot of them.

4) Is there a distance limitation?
Yes and No. For digital DVI cables there is a 5 Meter distance limitation which can be broken with Extra High Quality Cable.With that said some cards do not even work upto 5 Meter..

5)Tell me about the Digital Interfaces available?
Currently there are three digital interface standards (P&D, DFP, and DVI) in the market. DVI is becomming the defactor Standard in the industry.

DVI Connectors

 

A DVI connection can be one of three types - DVI-I, DVI-D or DVI-A.
DVI-I:
DVI-I contains both the digital and analog connections, (DVI-D + DVI-A) , it's essentially a combination of DVI-D and DVI-A cables within one cable. The I is for Integrated meaning a combination of both signals D and A.
DVI-D:
DVI-D (like DFP or P&D-D (EVC)) is a digital only connection. If both devices being connected support a Digital DVI connection (DVI-I or DVI-D compatible) and are compatible in resolutions, refresh rates and sync, using a DVI-D cable will ensure that you are using a digital connection rather than an analog connection, without playing around with settings to assure this.
DVI-A:
DVI-A is not often used on any cables but is in fact a DVI-I Cable with the other side have a HDDB15 Connector.
Dual Link: Dual T.D.M.S. (transition minimized differential signaling) "links". DVI can have up to two TMDS links. Each cable provideo two links each holding three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second. Dual-link connections provide bandwidth for resolutions up to 2048 x 1536p.
Single Link: Single T.D.M.S. link. Each link has three data channels for RGB information with a maximum bandwidth of 165 MHz, which is equal to 165 million pixels per second.
Bandwidth for a single-link connection supports resolutions of over 1920 x 1080 at 60 Hz (HDTV).
