About VGA
The information processed by the graphics card is ultimately output
to the monitor. The output interface of the graphics card is the
bridge between the computer and the monitor. It is responsible for
outputting the corresponding image signal to the monitor. Due to
design and manufacturing reasons, CRT monitors can only accept
analog signal input, which requires the graphics card to output
analog signals. The VGA interface is the interface that outputs
analog signals on the graphics card, and the VGA (Video Graphics
Array) interface is also called the D-Sub interface. Although LCD
monitors can directly receive digital signals, many low-end
products use the VGA interface in order to match the VGA interface
graphics card. The VGA interface is a D-type interface. There are
15 pins on the top, divided into three rows, five in each row.
The VGA interface is the most widely used interface type on
graphics cards, and most graphics cards have this interface. The
port has one male and one femaletwo maletwo femaleclass
The VGA interface is a D-type interface with a total of 15
pinholes, divided into three rows of five. Among them, in addition
to 2 NC (Not Connect) signals, 3 display data buses and 5 GND
signals, more important are 3 RGB color component signals and 2
scan synchronization signals HSYNC and VSYNC pins. The color
component in the VGA interface adopts RS343 level standard. The
peak-to-peak voltage of the RS343 level standard is 1V. The VGA
interface is the most widely used interface type on graphics cards,
and most graphics cards have this type of interface. Some graphics
cards that do not have a VGA interface but have a DVI (Digital
Visual Interface) interface can also convert the DVI interface to a
VGA interface through a simple adapter. Usually a graphics card
without a VGA interface will come with such an adapter. .
Nowadays, most computers and external display devices are connected
through an analog VGA interface. The digitally generated display
image information inside the computer is converted into R, G, and B
primary color signals and lines by the digital/analog converter in
the graphics card Field synchronization signal, the signal is
transmitted to the display device through the cable. For an analog
display device, such as an analog CRT display, the signal is
directly sent to the corresponding processing circuit to drive and
control the kinescope to generate an image. For digital display
devices such as LCD and DLP, the corresponding A/D (analog/digital)
converter needs to be configured in the display device to convert
the analog signal into a digital signal. After D/A and A/D2
conversions, it inevitably caused some loss of image details. VGA
interface is no exception for CRT monitors, but it is used to
connect display devices such as liquid crystals. The image loss
during the conversion process will slightly reduce the display
effect.
