VIDEO CARD (or badge)

Thegraphics card It is the one that regulates and delimits what is shown on the computer monitor (images or text). We explain what a video card is, what it is for, its features and more.

What is a video card?

The graphics card It is the device that has the function of regulation and determining how the images and the text that can be observed in the monitor of a computer. In that sense, a video card is the one that will send the signals to the monitor, projector or television. Depending on the quality of the computer's video card, there is going to be a certain influence on how the image is represented, especially when playing, during video or 3D editing.

What is a video card for?

The graphics card It is the one that is responsible for translating the information that the computer is processing from each of the instructions that are given to it, in order to show it in a way that can be immediately understood by the common user. That is why it is usually stated that the video card is the one that decodes and decodes the language that is given by the computer's processor, to generate a conversion into images, symbols and representations for the end user.

Types of video cards

It is very important to highlight the video card types that today there are many brands and models that exist, so the following classification is useful more than anything to have a historical context of its development.

Super VGA Cards It emerged in 1989 and supported a resolution of 850 x 600 pixels, with a color range of 16.7 million, although the number of colors simultaneously was restricted.

VGA card It is a graphic model designer by IBM. It became a de facto model for computers. They used analog signals this is the reason why a monitor for previous versions cannot use this card.

Hrcules card It is a video card that was designed by Van Suwannukul when preparing his doctoral thesis.

MDA card It was a very old model for the screen of the computers that IBM built. Its resolution for texts was 725 x 360 pixels.

CGA cards It is a very old video card. It was a color graphic card for IBM computers and was thought more than anything for computer video games.

EGA card It is a card created in 1984 by IBM. With its development the tones increased, the resolution of the graphics and texts.

Parts of a video card

  • VGA or standard port It is the connector where the cable of a computer will be installed to send the output signal to the monitor.
  • DVI port DVI or Digital Video Interface, it is a connector for output to flat digital monitors.
  • HDMI port HDMI or High Definition Multimedia Interface, which is an output connector with a high quality multimedia interface which can be used for the connection of any kind of device that supports that technology.
  • TV port In certain cases the video cards include this component so that it can be seen on television, although a chip is required to convert the digital audio signal into analog so that it can be compatible with that of a TV.
  • Memory A video card also has its memory to store the information that is then shown, the more memory it is, the greater the amount of data that is processed and with better quality when it is presented on the monitor.
  • Video chip It is almost the CPU of a video card and is known as GPU or Graphics Processing Unit, where it is responsible for the generation of the calculations that are required to display an image and thus save time and energy for the microprocessor of a computer.

Features of a video card

  • Cooling unit It is a central feature to look at, particularly to ensure that it is well maintained during long working hours. Remember that heat is a key issue in which to protect yourself around electronic components.
  • Vram The amount of Vram or dedicated memory of the video card to facilitate and improve the rendering of the frames. The card is not always bigger, the more powerful the card is, although there is a relationship.
  • Rear connections Depending on how you use it, the video card may include different ports, which may be convenient for connecting different monitors, for example.
  • SPF Are the frames per second or SPF and it is the amount of images that can pass through the monitor in just one second. The typical thing is that they are 30 FPS for an optimal experience, from 60 FPS it is excellent and superior from 100 FPS onwards.
