Image transmission cable for the optimum visual experience

The Digital Visual Interface, or DVI for short, is an interface for transmitting image signals. The DVI connection is usually found on computers. DVI cables enable both digital and analog image transmission. The DVI connection was the first standard to enable the digital transmission of images from a graphics card to a monitor. Compared to other interfaces, the DVI interface had a higher bandwidth, supporting a resolution of sometimes more than 1920 x 1200 pixels. Accordingly, the DVI cable replaced the analog VGA cable and can still be found today on various devices such as graphics cards, monitors or televisions.

DVI-A, DVI-I or DVI-D cable?

The former standard is divided into different subtypes. On the one hand, there is the DVI-I interface. This allows both analog and digital image signals to be transmitted. On the other hand, only digital transmission is possible with the DVI-D interface. Only analog signals are transmitted with the DVI-A interface, although this subtype is rarely used.

Which DVI cable you need depends on the connection of your hardware. At INTOS, you can obtain DVI-D and DVI-I cables both as single link and dual link versions with a different number of pins and in different lengths. The advantage of DVI-I cables is that they are compatible with DVI-D and DVI-A connections. Whereas DVI-D and DVI-A connections can only be used with the cable of the same name. By the way: With an HDMI adapter, you can continue to use your DVI cable and therefore your old device.

DVI cable: Single Link or Dual Link?

With DVI-I and DVI-D, a distinction is made between single link and dual link. The difference is noticeable in the bandwidth and correspondingly in the resolution. With 18 + 5 pins, the DVI-I cable in the Single Link version has six pins less than the Dual Link version with 24 + 5 pins. This has an effect on the resolution. Single Link DVI-I cables have a maximum resolution of 1920 x 1200 pixels at a transmission rate of 3.96 Gbit/s. Dual Link DVI-I cables achieve a resolution of 2560 x 1600 pixels and a full 7.92 Gbit/s. The situation is similar with DVI-D cables. They also achieve the same performance, but the single link variant only has 18 + 1 pins and the dual link variant has 24 + 1 pins.

Whichever DVI cable you need, your cable specialist will provide you with different versions in the usual InLine® quality, whether as an extension, PC and MAC compatible or with gold-plated contacts for better conductivity.
