What is DVI?
Digital visual interface or digital video interface , better known as dvi , is the standard video interface. It was established by the Digital Display working group (DDWG) to maximize the resolution of digital displays with a flat panel. Visual Graphics Array (VGA), Standard before DVI, is an analog technology that has been designed for monitors of the cathode ray tubes (CRT).
Why the DVI transition? Graphics cards generate digital signals, which then pass random digital access memory to an analog converter (RAMDAC), where they are converted to analog signals to suit CRT monitors. Conversion from digital to analog "slurs" signal in a small way that results in a picture that is not as sharp as it should be or would be if purely digital. This explains why, as the CRT analog monitors increased and the resolution greater, the text was not as sharp as it should be, and very small script was blurred. NaturalThe development was to create an Industry switch to digital digital displays with digital interfaces.
DVI eliminates an unnecessary analog interpreter from the translation of digital signals between digital components. The digital flat panel shows the method, each pixel is mapped to a numeric value that determines its brightness level every time the frame is painted, which occurs many times in a second. It is inherently more demanding than CRT technology. When analog conversion is eliminated, the result is optimal. If the digit is "1" handed over, the receiver gets "1" and nothing else. If it is sent via an analog, "1" may look more like 0.952 or 1.002.
Intel, IBM, NEC, Compaq, Fujitsu, Hewlett Packard and Silicon The image created the DDWG consortium that has developed DVI. The market went from the old VGA standard to the DVI standard with many flat panels and graphics cards with VG interfacesAnd even DVI express it projected components. There are several types of DVI cable formats for different hardware standards. Since then, DVI has been replaced by two newer digital standards: Unified Display Interface (UDI) and DisplayPort .
