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.
