All About DVI Connectors and Cables You Need to Know

The DVI or Digital Video Interface is a technology for video display. Prior to DVI the VGA technology had been used extensively around the world as a popular video display technology till the year 1999. After 1999 the DVI technology replaced the VGA and is used very popularly worldwide. You can get the best dvi cable including the connectors as well as all DVI technology-related services at any nook and corner without searching much for them.
The DVI connectors, as well as the cables, are used to connect a video source, for example, a graphics card to a computer monitor for the purpose of displaying the video. However, there are different other options to connect a video source with display devices such as VGA, DVI, and HDMI. You can also find different three types of connectors in the DVI technology such as (1) DVI-A where the A stands for Analog, (2) DVI-D, the D stands for Digital, and the (3) is DVI-I which stands for Integrated. These three types of DVIs are further divided into two types based on the data rates such as single link and dual-link.
The DVI connectors use the TDMS or the Transition Minimised Differential Signal for the purpose of transferring data through a pair of twisted wires. The single link DVI connectors have these types of TDMS data transferring system. Every TDMS link further corresponds to the blue, red and green video signals and the extra TMDS link normally is a clock control channel. The single link channels support 1920 x 1200 resolution at 60 Hz refresh rate. Eventually, these connectors offer a bandwidth of 1.65 Gbps and can operate at a maximum of 165 MHz and that is how a single-link DVI connector works.
On the other hand, the dual-link DVI connectors contain double the numbers of TMDS pairs in comparison to the single-link DVIs. The dual link DVI connectors do not contain a clock pair and can enable bandwidth with 2 Gbps. These systems further are backwards compatible with the single-link DVI types and can support 2560 x 1600 resolution at a refresh rate of 60Hz. However, the dual-link DVI connectors are not supported by the single-link DVI connectors. In addition to this, one TDMS transmitter is used in a single-link DVI connector to send digital information whereas the dual-link DVI uses two transmitters. Ultimately, the dual link DVI connectors are more popular by the users in comparison to the single-link DVI connectors.
