What is single link and dual link DVI


What’s the difference between Single Data-Link and Dual Data-Link DVI?

A Single-Link (also known as a Single Data-Link) cable uses a single transmitter to send information across. A Dual-Link (or Dual Data-Link) DVI cable uses two transmitters and can relay a great deal more information and data across the wire (almost twice as much). This increase in data manifests as improved image quality, signal strength, and greater resolution support. Physically a Dual-Link cable will contain many more pins than a Single-Link cable so it is important to check for device compatibility before determining which cable is the correct one.

  1. Dual link support both the formats, while single link only support single-format. However, there are almost no devices on the market today which offer dual-link, so it really doesn’t matter either way.
