VGA also is known as D-Sub 15-pin or mini D-Sub 15-pin has a D shaped shell with 15 pins arranged in 3 rows.
VGA standard only uses analog signals however, other D-Sub cables such as serial ports are designed for transmitting digital signals as well. When used for transmitting video signals it is also known as VGA.
DVI is a D shaped shell that also uses pins to connect to the channel which forms the basis for the confusion of DVI and VGA cables.ĭVI with the dual signal link can support video images of 2560 × 1600 at 60Hz whereas a single signal link DVI can stream 1920 × 1200 at 60 Hz resolution.ĭ-Sub, a short form of D-Sub miniature, is an electronic cable introduced for multipurpose use in 1957 that is mostly obsolete in the present times. The DVI-I standard was in widespread use due to its compatibility with both analog and digital signals and thus its rapport with VGA cables which allowed it to be used for connecting input and output devices with both plug-in types.ĭVI or Digital Visual Interface is a hot-pluggable cable that is mostly used for computers and laptops. DVI-I: transmits both analog and digital signalsĭVI-A which used analog signals, is mostly out of use while DVI-D which is digital-only and DVI-I which supports both digital and analog signals are still heavily used in the LCD monitors.There are three main types of DVI, which are: DVI was curetted to transmit digital as well as analog signals and was known for its clearer and crisper video quality. DVI was introduced in 1999 for commercial use and was specifically made for supporting visual displays of higher resolution.
