What is called DVI

The DVI (digital video interface) is an interface to transmit video signals and meta data. It represents the advancement of the old S-VGA standard and has been established alongside with HDMI to connect computer monitors and TV displays.

Notable advantages of the DVI standard

The great success of the DVI standard within IT applications lies the ease of handling and the superior image quality.
DVI is hot-plug capable. You may connect or disconnect components to or from each other while they are in use. This advantage can be put to good use when connecting notebooks to displays or other mobile devices like e.g. a projector.
The image quality is clearly superior to analog interfaces. The reason for this is quite simple: The digital output signal does not have to be converted to an analog signal for transport. The data stays digital all the way, thus preventing any loss quality at all.
To provide the best compatibility possible the DVI standard can be used to transport even analog signals where needed within the same cable instead of digital data. A simple adapter will connect your legacy display device to a modern DVI equipped source or vice versa.

DVI is also compatible to HDMI and may be used to easily connect a computer or notebook to a TV display only providing a HDMI interface. InLine got several high quality tested adapters for a seamless adaptation of different video standards.
Please not that DVI does not process audio data like HDMI. Therefore the audio signal may be transported by an extra cable like e.g. an RCA cable, if necessary.

Note: Actually many major companies like AMD for video cards or Dream Media for DVB receivers are in fact using the DVI interface for audio data as well since many TVs and displays with speakers support this. So it may be advised to check if your device will support audio over DVI before using a RCA cable to transmit the audio signal.

DVI-D (digital only) only transmits video data. There are two different versions: SingleLink and DualLink. A single link connection can handle resolutions of up to 1600*1200 @ 75HZ while DualLink is capable of handling even UHD (4K) video streams.
There is no need to use a DualLink cable for low resolution, low framerate formats, but you may want to go for a DualLink cable anyway because most displays support well more than 75HZ, so you may want to check the needed refresh rate capability first before choosing a SingleLink cable for your application to avoid low-refresh rates and time consuming returns.

DVI-A (analog only) only transmits analog video data. This category is only mentioned for completeness. It is not commonly used and only exists to provice strict backward compatibility utilizing the new interface connector or cables.
