The DVI stands for Digital Visual Interface which is a standard of video interface designed by the Digital Display Working Group-DDWG in order to maximise the quality of vision in the digital devices such as flat-panel LCD computer and digital projectors. The DVI is primarily meant to establish a connection between the computer and display devices. There are four basic characteristics of DVI namely (1) digital transmission of visual signals without loss, (2)the independence of display hardware, (3) EDID and DDC2B plug and play abilities and (4) support for Analog as well as digital transmission through a single cable. Get your DVI cables and the connectors from Primecables.ca in order to ensure the four characteristics of DVI connectors and cables.
The DVI uses the data format based on the PanelLind serial format named TMDS or Transition Minimised Differential Signalling. The single link of DVI is comprised of four twisted wires each having different colour such as blue, green, red and black. These wires transmit 24 bits per pixel with the time of the signalling that is almost similar to an Analog signal. Eventually, the picture gets transmitted line by line with intervals of blanking between every line and each frame. In DVI you cannot transmit the changed parts of an image and cannot do the compression either.
The largest resolution in a single DVI link is 60 Hz at 206 megapixels and this is the reason the DVI has a secondary link comprising another pair of blue, green and red twisted wires. Whenever maximum bandwidth is needed more than the performance of single link, the secondary link is enabled so that the alternate pixels get transmitted.
There is a necessary specification in the DVI for fixed single-link 165 Hz cut-off point where the display modes which require less than 165 Hz should use the single-link. On the other hand, the display modes which require more than 165 Hz must switch for dual-link. In the cases where both links are used, the rate of the pixel may exceed 165 MHz. You can also use the second link when you require more than 24 bits per pixel but in this case, it will carry the least significant bits. The DVI connectors come in two forms namely the DVI-I digital-only comprising 24 pin version and the DVI-I digital and Analog version with 29 pins.
