Standard VGA graphics adapter. Description of the VGA graphics adapter. Recognizing a video card using Device ID

The VGA graphics adapter is designed to connect monitors to a computer. By the way, at the moment this type of connection is considered out of date, since technology does not stand still and this connector has been replaced by more advanced options for connecting to monitors.

Due to the appearance on the market of monitors made using liquid crystal technology, the power of the VGA graphics adapter has become insufficient. Therefore, more advanced types of connectors with greater potential began to be inserted into graphic cards.

What is VGA?

So, a VGA graphics adapter is a connector for analog connection to a computer. This connector appeared in 1987 at IBM, which created such connectors for new generation computers.

In the motherboard, the VGA graphics adapter was connected to the graphics card. The maximum screen resolution that could be supported at that time was 640 x 480 pixels.

Many modern models support connection to the VGA graphics adapter connector, but only on monitors whose resolution does not exceed 1280 x 1024 pixels and the screen refresh rate reaches 75 frames. If you connect a higher resolution monitor via VGA, then large losses in quality will be noticeable and the image will lose its clarity.

VESA DDC

The first version of the standard VGA graphics adapter connector to a monitor was DDC. Released in 1994, this adapter ensured stable operation of the connector and monitor, being able to detect many types of physical flows. The work was supported in EDID 1.0 format.

The next version of this connector, which appeared in 1996, included an already updated EDID format that supported the unique DDC2B+ protocol. A year later, this interface was updated, which entailed the acquisition of an improved protocol - DDC2Bi, and support for VESA Plug and Display was implemented.

Since 1999, it was decided to replace DDC with E-DDC, but EDID can still be found today, since it serves as an auxiliary standard that can be used to determine which format was used when compressing a binary file. This file contains information about the properties and modes of the graphics monitor, which are recorded in the memory chip by the monitor manufacturer.

DDC1

The DDC1 connector is a VGA graphics adapter that allows the monitor to transmit all of its information to the computer using one-way communication. It works this way - the video card recognizes information about the cable, then, using vertical sync pulses, reads it synchronously.

DDC2

This VGA graphics adapter already had the ability for two-way data transfer. It looks like this: the monitor transmits its data, and the computer automatically adjusts to the received data in order to adapt the operation of the monitor.

Homemade cord extension for VGA

Due to physical limitations, there are times when extending the VGA graphics adapter cable is simply necessary. The simplest option would be to purchase a cable of the required length, but then the question arises about its cost, which is prohibitively inflated.

Another reason for a homemade option could be pulling the cable to another room. If making a hole in the wall up to five centimeters in size is not an option, then a homemade extension is what you need.

The best option would be to operate the VGA RJ-45 graphics adapter without any soldering, because their absence will simplify the task by simply crimping the ends of the twisted pair with shielded braid.

The best options for extending the VGA cable are an adapter from this port to tulip plugs.

Now VGA connectors have been replaced by more advanced options for transferring images from a video card to a monitor - this is the DVI connector. But despite this, many video cards still support this connection option.

Sometimes a user needs to find out the model of his video card. And this can be done in several ways.

Via Device Manager

To open device Manager devmgmt.msc. Will open device Manager, in which click on the plus sign next to the category Video adapters. As you can see in the screenshot, the PC has an ATI RadeonHD 6800 Series video card.

If instead of the model it says “Standard VGA graphics adapter,” this means that the drivers for the video card were not installed, so Windows cannot determine its type and model.

Likewise, if there is nothing in Video adapters, and in Other devices If “Video controller (VGA-compatible)” or “Standard VGA graphics adapter” is located, this again means that the official driver was not installed, so Windows installed its own driver. In this case, you can find out the driver version like this: click on Standard VGA graphics adapter(or Video controller (VGA compatible)") right-click and select Properties.

In it, switch to the tab Intelligence, and in the section Property change the item Device Description on Equipment ID.

In chapter Values right-click on the first line and select Copy.

Paste the copied text into a search engine. As you can see in the screenshot, the video card you are looking for is ATI Radeon HD 6800 Series.

Via Screen Options

To do this, right-click on an empty space on the desktop and select the item in the context menu Screen resolution. In the window that opens, find Extra options and open them. A window with the properties of the graphic editor will appear. In chapter Intelligence about the adapter, find the item Adapter string. What is written next to it is the video card model.

Using the program

This program will help you find out the manufacturer of your video card, its model and driver version. And if the driver is missing, Everest will also tell you the official website of the graphics adapter manufacturer, where you can download its latest version.

Via DirectX Diagnostic Tool

To open DirectX Diagnostic Tool, press Win+R on your keyboard and in the window that appears, write dxdiag. Switch to tab Screen and in the section Device you will see the manufacturer and model of the video card.

Removing the system unit cover

Typically, video cards always indicate its manufacturer and model.

Hello admin, I ask you not to judge strictly for the question, since I am a beginner in the computer world, please explain what it is? I recently reinstalled the Windows 7 operating system on my own and went into Device Manager to check the situation with the drivers, but as surprising as it may sound, all the drivers were installed, and I didn’t see any yellow triangles with an exclamation mark. Imagine my surprise when several of my games did not work, producing various errors upon startup, although everything was fine before the reinstallation. One of the forums on the Internet advised installing drivers on the video card. And in fact, in the Device Manager in the “Video adapters” item there was no name of my video card, but there was such a device as VGA compatible video controller.

VGA compatible video controller

Hello friends! This means that the operating system has installed its standard driver for your video card and called your video card this way VGA compatible video controller or Standard VGA adapter,
