What You Need to Know about Mini DisplayPort Male to DVI-D Dual-Link Male Cables and Adapters

DVI-D and Mini DisplayPort are both digital video display formats. These particular cables have a Mini DisplayPort male plug on one end and a DVI-D male plug on the other end. They are used to connect a DisplayPort video source such as a computer to a DVI-D display such as a monitor, television set, or projector.

What is the resolution of a Mini DisplayPort to DVI cable?

That depends on the particular cable you are using. Both DisplayPort 1.1a and DVI-D support a resolution up to 2560×1600 pixels, although DisplayPort 1.2 supports a resolution up to 4096×2160 pixels. Some cables may support a resolution as high as 2560x1600 pixels. However, the resolution may be capped at a lower number such as 1920x1200.

What type of interfaces are compatible with these cables?

That depends on the format. The Mini DisplayPort plug is only compatible with a Mini DisplayPort interface. It will not fit into any other type of port. A dual-link DVI-D cable will work with any DVI-D interface, despite the physical differences between dual-link and singe-link. DVI-D is also compatible with any DVI-I interface, which supports both a digital and analog signal. It is not compatible with the analog-only DVI-A or the earlier VGA interface, however. The refresh rate, which is the rate at which the image on screen is updated every second, may vary based on the type of interface you are using.

What are the most common types of cables?

A Mini DisplayPort to DVI-D connection may come in the following forms:

  • Standard Cable: This type of male connector includes the cable only. It can simply be plugged into the video source and the display without any additional issues.
  • Adapter: In this setup, a Mini DisplayPort cable connects to a DVI-D adapter or converter box. The adapter itself is usually quite short, so you may need an extra DVI cable.
  • Splitter: A splitter can split a Mini DisplayPort connector into multiple DVI cables, or vice versa.
  • Hub: A hub resembles a large box with multiple connections in it. This allows you to connect multiple displays at the same time.
What is the maximum length of a cable?

That depends somewhat on the resolution. Both DVI-D and Mini DisplayPort have a maximum length of around 50 feet at lower resolutions. At higher resolutions such as 1920x1200, the length may only be 15 feet at most, although extenders will allow you to cover longer distances. The wiring itself is sometimes measured by a metric known as AWG, which stands for American wire gauge. AWG is a measurement between zero and 40. A smaller number means that the cable has a larger diameter, and it can, therefore, carry more current over longer distances.
