DVI Cables
Digital Visual Interface, or DVI, cables are seen as the next step in video transmission. DVI cables are gradually overtaking VGA cables, which were not in fact originally designed for LCD devices, but for CRT monitors. DVI connectors can incorporate pins to pass through the analogue signals using the VGA (Video Graphics Array) standard. This feature allows the DVI cable to be universal, as either a digital or an analogue monitor can be operated from the same connector as a result.
Depending on which signals a DVI connector implements, a device will have one of three names: DVI-A (analogue only), DVI-D (digital only) or DVI-I (analogue and digital). A DVI connector can also facilitate a second data link for high resolution displays, but many devices do not use this function. For those devices that do, the connector will sometimes be referred to as DVI-DL (dual link).
A few definitions of DVI cables follow:
DVI-I Cables up to 5m
Simply put, a DVI is a video interface which can maximise the visual quality of digital display devices when connecting liquid crystal displays (LCD), flat panel displays and digital projectors to output devices such as computers. Such cables are 5 metres in length and are compatible with digital and analogue data transfer, signified by the “I” in the title.
Premium DVI-D Super Long Distance Cables Up to 25m
You can maximise the visual quality of digital display devices when connecting digital projectors, LCDs and flat panel displays to computers and various other output equipment, by using a DVI video interface. This particular cable is for digital data transfer, signified by the “D” in the title, and spans a 25 metre length.
Fibre Optic DVI-D Cables Up to 100m
A DVI video interface will maximise the quality of LCDs, flat panel displays and digital projectors when connecting to computers and other output devices. This type of cable can use a length of 100m and uses fibre optic cabling to transfer data, which increases the speed of data transfer.
DVI to VGA Cables
Connect a VGA monitor with a built-in VGA cable to a computer with a DVI-I analogue, using DVI to VGA cables. This type of cable is useful when connecting two VGA monitors to a computer equipped with a modern graphics card which features both DVI-I and VGA connectors. All you need to do is connect the first monitor to the VGA port and the second to the DVI port, using this type of cable.
