What is the onboard VGA driver used for?

VGA is the graphics card driver.

The information processed by the graphics card is eventually output to the display, and the output interface of the graphics card is the bridge between the computer and the monitor, which is responsible for outputting the corresponding image signal to the display. Due to the design and manufacturing reasons, CRT displays can only accept analog signal input, which requires the graphics card to be able to input 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 the LCD can directly receive digital signals, many low-end products use the VGA interface in order to match the VGA interface graphics card. The VGA connector is a D-type connector with a total of 15 empty pins on it, divided into three rows of five each. The VGA interface is the most widely used interface type on graphics cards, and most graphics cards have this interface.

At present, most computers are connected with external display devices through analog VGA interfaces, and the display image information generated digitally inside the computer is transformed into R, G, B three primary color signals and line, field synchronization signals by the digital analog converter in the graphics card, and the signal is transmitted to the display equipment by cable. In the case of analog display devices, such as analog CRT displays, the signal is sent directly to the corresponding processing circuit, which drives the control CRT to generate the image. For digital display devices such as LCD and DLP, the display equipment needs to be equipped with a corresponding AD (analog-digital) converter to convert the analog signal into a digital signal.

After the D a and A D 2 conversions, it inevitably caused some loss of image details. The VGA interface is understandable for CRT displays, but when it is used to connect a display device such as a liquid crystal, the image loss during the conversion process will cause the display effect to decrease slightly.

VGA (Video Graphics Array) is a computer display standard proposed by IBM in 1987 that uses analog signals, which is very outdated for today's personal computer market. Even so, VGA is still a low standard supported by the largest number of manufacturers, and PCs must support the VGA standard before loading their own unique drivers. For example, the boot screen of Microsoft's Windows series products still uses VGA display mode, which also shows that its resolution and number of colors are insufficient.

The onboard VGA driver is the driver for the integrated graphics card that integrates the motherboard.

The graphics driver integrated into the motherboard is not a discrete graphics card Generally, such DIY machines are very cheap and have average performance If your graphics card is a discrete graphics card, don't install this driver

The VGA in the computer is the graphics card.

The VGA driver is the graphics card driver.

Yours is the integrated graphics. This is the graphics driver.

There are two cases:

If there is a discrete graphics card on the computer, it is inserted on the graphics card, which means that the computer uses the independent graphics card to work.

If there is no independent graphics card on the computer, plug it into the motherboard, which means that the computer uses an integrated graphics card to work.

Introduce the concepts of independent display and integrated display

An integrated graphics card is a component that integrates the graphics chip, video memory, and related circuitry on the motherboard.

There are separate graphics chips for integrated graphics, but most of them are integrated into the motherboard's northbridge chip; Some motherboard integrated graphics cards also have separate video memory installed on the motherboard, but their capacity is small, and the display effect and processing performance of the integrated graphics card are relatively weak, and the graphics card cannot be upgraded hardware.

A discrete graphics card refers to the display chip, video memory and its related circuits are made on a separate circuit board, which is self-contained and exists as an independent board, which needs to occupy the expansion slot of the motherboard.

Separately installed video memory, it generally does not occupy system memory, and it is much more advanced than the integrated graphics card in terms of technology, but the performance is certainly not inferior to the integrated graphics card, and it is easy to upgrade the hardware of the graphics card.

Yes, basic low-end entry-level liquid-excited chipset.

The motherboards all come with a VGA port.

There are also low-end motherboards of channel brands, most of which have VGA interfaces. Noisy socks such as A520M-HDV, H610M-T V20 all have VGA interfaces.

The VGA port on the motherboard is when the computer is not equipped with a discrete graphics card. It is used to output a display signal.

Nowadays, most desktop computers are equipped with a discrete graphics card, and the graphics card not only has a VGA port, but also an HDMI and DVI port. Select the signal cable based on the interfaces that the display also supports.

If you don't have a discrete graphics card, you'll need to use the graphics card connector on your motherboard.

As shown in the figure below, 2 is the VGA interface, 11 is the DVI interface, and 8 is the HDMI interface. to connect the display.

When there is a discrete graphics card on the computer and an external monitor interface on the motherboard, the computer's display signal cable is connected to the discrete graphics card by default.

This is the graphics card interface integrated into the motherboard, if you want to use it, you need to unplug the discrete graphics card, connect the data cable of the display to the graphics card, and you can use it directly.

Connect a projection or TV.

There is a VGA interface on the motherboard, and it is said that the motherboard comes with an integrated graphics card. If you don't have a separate graphics card, you can directly use the integrated graphics card on the motherboard to destroy the graphics card, and if you have a separate graphics card, you don't need to shoot wide.
