The video card also called the graphic card, has the responsibility of processing each data and information coming from the CPU and representing it in a graphic form on the computer screen or monitor. This internal device is structured in various ways.

They are also known as a video card, graphic accelerator card, video adapter, video card, each one has additional functionalities that allow computer manufacturers to offer variables, design options depending on the optimization of operating systems.

These alternatives allow, among other things, to obtain tuning with televisions, video captures, encoding for videos in various formats, complementing the interface through designs and images such as IEEI connectors, Joystick stylus, which help determine the firewalls in some computers.

Video cards are made by various companies that sell their technology to developers of computers, video games, televisions and devices that need a state-of-the-art graphic representation system. But let’s see what these types of graphics look like on video cards.

Chart Types

Video cards are made by various companies that sell their technology to developers of computers, video games, televisions and devices that need a state-of-the-art graphic representation system. But let’s see what these types of graphics look like on video cards.

Integrated graphics

It represents an alternative that refreshes the operation of the video card and the video hardware. They can be integrated into the motherboard. The integrated graphic system allows deactivating the chi function in the BIOs having an express input. which can help to incorporate an additional video card.

Integrated graphics allow the use of a motherboard. This reduces costs and allows lower energy consumption. However, the consumption of space in the CPU is great. despite having its own RAM, ventilation system

Dedicated cards

These types of cards are installed as a second GPU that is installed on the motherboard, as an additional device they serve to expand spaces and definitions, freeing up space for RAM memory in a large proportion, which can give more space to the operating system and programs. and some other operations that require the use of memory.

Generally, this type of card is integrated into portable devices where the so-called Intel Graphics stickers are included, which is Intel’s integrated graphics processor. This is caused by issues of space where the greatest profitability of the use of spaces and resources is required.


The first video cards really appear from the 60s, a proposal begins where the so-called monitors appeared, created to replace printer-type devices. These devices issued a card where the information was identified through codes.

The cards only visualized texts that later, through certain slots, showed the information. The first graphics chips were manufactured by the Motorola company. With the appearance of their model 6845 they allowed to equip some computers that had certain graphic capabilities.

First graphics cards Video card function

With the production of the first desktop or domestic PCs, as they were called in the beginning, the respective chip was inserted into the motherboard in which theatina 80 columns cards. These chips will allow to express text mode based on sizes ranging from 80 x 24 to 80 x 25 characters.

The first computers adapted to this format were the Apple II and the Spectravideo SVI 328 motherboard model. The cards that the IBM firm began to provide in 198, consisted of an MDA screen monochrome adapter. This card allows to work in the form of text and could represent up to 25 lines of 80 characters on the monitor.

Its still small memory of 4 Kb, could work a single page, on single color monitors which were generally green with the natural background of the screen in black. In the 80s, video games began to expand and many companies began to manufacture cards to give scope to on-screen actions.

Between the years 1980 and 1990, various models of graphics cards appeared that little by little gave force to the development and evolution of other models. In the case of the video card function for computers. The MDA models appeared in the year 81 with a text mode of 80 x 25 characters, and 4 Kb memory, then the following followed:

  • CGA in 1981 with a text mode of 80 x 25 characters and memory of 16 Kb.
  • HGC year 1982 of 80 x 25 characters and memory of 265 Kb.
  • EGA, available on the market in 1984 with a resolution of 80 columns for 25 characters and a memory of 256 Kb.
  • IBM, in 1987 equal to 80 x 25 characters and a graphic mode of 1024 x 768 resolution, 256 Kb memory.
  • MCGA, also from 1987 with 80 x 25 characters and 320 x 200 graphics mode, 256 Kb memory.
  • VGA, in 1987 with range in graphics mode between 640 x 480 to 700 x 400, had a memory of 256 Kb.
  • SVGA, was released in 1989 and had an expanded memory of 1 Mg with characters of 80 x 25 and a graphic mode between 1028 and 728
  • XGA, from 1990 with 80 x 25 characters and a graphic mode of 1024 x 768 with 2 Mb memory.

90’s Video card function

One of the most important graphics adapters that was born in the early 90’s was the VGA model. Various video game and desktop computer equipment manufacturers found this video card function model to be more adaptable to their needs.

The resolution and the number of colors allow to significantly improve the adaptation to the screens. In the mid-90s, the Super Video Graphics Array (SVGA) was born. With more than 2 mg of memory and resolutions that ranged from 1024 x 768 pixels, this task allowed to emit more than 256 colors.

Companies like Apple opened the field for video cards, launching the market as a counterpart to the SVGA called Commodore Amiga 2000. This card allowed creating professional applications, that is, it had the possibility of adapting other video chips to the GPU.

By 1995, the graphics card market made great strides when the first 2D and 3D cards appeared, manufactured by the companies Matrox and ATI. These cards allow to work under the conditions of SVGA cards, but incorporating 3D technology.

The Voodoo graphics chip from the 3dfx company, appeared in 1997 showing a capacity for calculation and new 3D effects, that is, movements such as z-buffering, mip mapping, etc. began to be observed on the screen. From then on, evolution took important steps.

Graphics cards like the Voodoo2 appear, even made by various companies. The main feature of this type of graphics card was its power. This caused band ports to fall short and updates were lagging in the lab.

For this, the Intel company developed the Accelerated Graphics Port (AGP), which allowed to solve the limitation between the processor and the card giving better visual presentation and efficiency.

Year 2000 onwards Video card function

During the beginning of the 2000s, various video cards appeared, however the one that had the most impact on developers, which also serves to expand visualization in video games, was the Peripheral Component Interconnect (PCI). This type of card, which would later be the most adapted to PCs, made it possible to eliminate bottlenecks.

This was a problem that was generally generated by the presence of internal buses of the so-called ISA (Industry Standard Architecture). This way of placement and use of the graphics cards, made the VGA model cards soon to leave the market. Other PCI bus-type platforms allowed the development of new graphics cards.

The growth and development came with the NVIDIA company, which began to dominate the graphics card market. It acquired 70% of the assets of the 3dfx company, allowing it to have the capacity to put on sale a line of graphics cards called GeForce. These models were oriented towards 3D algorithms.

The speed of the graphics processors increased considerably. But they had disadvantages, the memories needed more space. If you need to know more about this topic, I invite you to learn more by clicking on this link ROM memory as a way to expand the capacity of graphics cards.

The memory of the video cards increased their capacity and went from 32 Gb, which was the capacity of GeForce video cards, to the GeForce 4 models that had at the moment capacity between 64 Mg to 128 Mg. With the development of sixth generation video game consoles and computers with better options.

The use of greater capacity of RAM memory in the video cards was required. This made for example that the Apple company will incorporate chips from NVIDIA and ATI, for the first innovative computers called iMac. Other companies carried out Powerpcs, which have a built-in PCI or AGP bus using non-CPU dependent graphics cards.

By the mid-2000s companies ATI and NVIDIA had dominated the video card function market, GeForce models totally dominated the market. A few years later, the ATI company was acquired by the AMD company, which some years later would dominate almost entirely the manufacture of graphics cards.

At present, this company manufactures together NVIDIA various video cards that are incorporated into the computers that are manufactured daily in the world. They also distribute various graphics cards for other non-computer or computer-related companies.

Resources and components Video card function

To appreciate the function of a video card it is important to know that it requires a number of resources and components that allow data to be processed and adapted to a video monitor at very fast speeds. Also provide the best view and resolution to the user.

But what is the function of the video card ? The graphic processing unit, as it is also called, not only helps to present on a screen all the information that the user needs, but also processes various types of information that in turn consumes a number of resources.

For that you need items and settings that consume memory and power. Next we will detail these elements and components that allow to create the function of the graphics card.

GRAM Graphic Memory Video card function

Called graphic random access memory, they are chips that store and transmit information between them. Some reduced specifications and determinations may change the initial setting.

The graphic memory has several means that are incorporated in the different computers or motherboards according to the importance and need of the manufacturer. This allows various options to be displayed on the screen, which may vary from one equipment to another. Let’s see what they are:

  • Dedicated memory, consists of a memory that is inserted in an isolated way to the GPU (which we will see later) and allows to use its own resources, this helps that the independence in the memory capacity does not affect the RAM.
  • Shared Memory, is a memory that uses direct resources of the RAM memory limiting space and capacity elements.

Graphics memory is the life of any computer or video game equipment, the processed data must be managed efficiently and quickly. That is why they are part of the most important components of the entire video card complement, among the most important features are:

With respect to the memory interface also called Data Bus, it consists of the way in which the bit width of each chip is multiplied according to the number of units. This feature also allows, together with memory frequency, to establish the amount of data that is transmitted in a given time (bandwidth).

Memory frequency consists of the number of times memory can carry the data it processes. To learn more about the conformation of these forms, check the following lilnk related to the Data Structure . It is a complement to the memory interface that helps to determine the total bandwidth in a given time.

This memory frequency is measured in Hertz and is designed according to the characteristics of the motherboards and the capacity of the equipment. There are various models that complement this information.

Another determining characteristic is the bandwidth called AdB. It consists of a data rate that allows them to be transported in half the established time. When there is insufficient bandwidth the power of the GPU decreases. There the importance of its model and type.

On the other hand, the transmission is measured in Gbps (Gigabytes per second) and is what converts the data into resolutions for the images and in turn converts the bits into Bytes, which helps effective transmission.

The “z buffer” is another important element that allows managing the depth coordinates generated by 3D images. It uses a large memory space which helps to improve depth in images.

It is believed that the most relevant characteristic of graphic memory is represented by capacity. This is measured by the number of data and texture it must process. When a graphic memory limits its capacity, delays are observed in the processes and it is necessary to wait for certain data to be emptied.

Many times the user is told that the performance of a graphics card is determined by the capacity of its memory, however the resources that Africa uses the most memory comes from VRAM

GPU graphics processing unit Video card function

The device is very similar to a CPU dedicated to graphics processing, its main function is to reduce the workload of the central processor. Thus, it allows optimizing the calculation of the floating points that predominate in the 3D function.

The information the GPU allows generally comes from the characteristics of the graphics card, that is, it is determined by it. Graphics cards of this type generally have very similar characteristics, for example the core frequency can oscillate between 825 MHz when the card is of low configuration.

Other cards can even go up to 1600 MHz when their range is higher. The shaders and pipes that are responsible for reducing the 3D image in proportion also vary for the high and low ranges. But let’s look at the elements that make up the GPU.

  • The ROP, is the device in charge of presenting the data processed by the GPU on the screen, it is also in charge of processing the smoothing and anti-aliasing filters.
  • Shaders are also called shaders, which are more powerful elements of the GPU, with them and being unified they are assigned the name of CUDA, which means a processor of data flows. This term is coined by the NVIDIA company. These elements are part of an evolution from the old pixel and vertex shaders.
  • The GPU can contain different amounts of core, the variation of expressed when the model of the same changes. Where various integrated chips are included that allow to increase the power with respect to the previous models.

RAMDAC memory Video card function

It is a random access memory analog digital converter. It also becomes a processor and converts the signal when it comes in digitized form and sends it to the RAM memory, in such a way that it transforms the analog signals to the memory itself.

We then see how certain images can be defined differently. This type of memory depends on the number of Bits that can be processed at the same time and the speed at which they transmit. This converter is capable of supporting the different speeds that allow to lighten the load towards optimal transmission levels.

Motherboard interfaces Video card function

The interface must be complemented with a series of elements which help to develop a series of visualizations and actions, where the user little by little directs the interface. It has been developing elements that have managed to implement state-of-the-art technology on the screens today.

The components that are manifested in this element are given by various evolutions and updates that range from the 8-bit MSx slot developed in the 80s, to the PCI-Express, called PCIe, which since 2004 have remained together with the AGP interface.

The models that nowadays function as the main interface are based on characteristics such as Bus, Width (bits), Frequency (MHz) and Bandwidth (MB / s) and the type of port, then we have the most used models such as the ISA 8-bit XT with a frequency of 4.77 MHz and a bandwidth of 8 MB / s a ​​parallel port.

Although it is not one of the most used, even more updated interfaces such as PCIe x 16 with bits between 1 and 16 bits and the variable frequency of 25 50 MHz can be connected with a bandwidth that ranges between 3200 and 6400 Mb / s. The port comes in series and sometimes parallel.

The exit

When this term is spoken it is understood as the process in which the connection forms allow data to be transmitted to a monitor or several monitors. We invite you to click on this link if you want to connect two monitors to a laptop which will help you learn more about these issues.

The optimization of the output and its compatibility with the activity of the monitor called the viewer is established as a function of the video card, there are many forms and types, let’s see:

DVI output Video card function

Called digital visual interface is a digital output of the interface that replaces the traditional outputs in computers, always digitally designed to obtain a quality display on projectors and digital screens. This type of output avoids the distortion and noise that a pixel can generate in the native resolution of the monitor. Today it competes with the HDMI output as one of the most innovative.


This form of port output is one of the most used nowadays, together with the previous output element they make up two of the main elements in the way of presenting the interface with better definition. This technology transmits clear images and audios in a comprehensive and defined way.

Vga Video card function

It represented for a time a type of more dynamic technology used during the 90s, it allowed to establish on the screens of functions that were called “video graphics array” (VGA) and “Super video graphics array (VGA). It supported monitors that work with cathode ray tubes and was replaced by the technology described at the beginning.


It is a type of output port created by the VESA company to compete with HDMI technology, it represents a high resolution interface. It can be incorporated into any equipment, so it has tabs to anchor to the connector that prevents accidental decanting.

S-Video Video card function

It is called separate video or separate video, it represents an output of very little use that also allows you to tune some televisions and control chips for NTSC / PAL signals, they were widely used during the DVD boom but are already falling into disuse.

Analog Video card function

This outlet known to many is one of the simplest and some video game companies, cable companies. Various devices used in their connections, generally the connector known as RCA (Radio Corporation of America) was used.

Component output

It is a type of analog output also responsible for transmitting high definition videos, it is used for projectors with quality similar to that of SVGA. It is made up of three connectors where in some equipment they are marked as follows (Y, Cb and Cr). It came to be used a lot in certain computers, but it is now only used for some sound equipment and certain video games.

Digital TTL Video card function

It is a model DE-9 connector, it was used for a long time to connect IBM screens. It allows compatibility with VGA, MDA, EGA technology, among others. Today it is totally in disuse.

Cooling system Video card function

We know very well that one of the devices that works the most in a computer, video game or other modern device is the graphics card. From the moment the equipment is turned on, it begins to operate and transmit and manage information.

This causes that the temperature of the video card present some increase. The workloads are large, generating heat that can cause damage to circuits and other alternate systems. Among the consequences there are blocking problems or failures in the screen and the card itself.

The incorporation of devices to lower the temperature are called refrigerants that allow to eliminate the excessive heat of the cards. The models also come with various types of fans or coolants, let’s see a few.


They are passive type devices, they are not composed of moving parts so they are silent. These devices are made of metal that allow the heat that is extracted from the card to be conducted. They work based on the structure and the total surface of the card, that is to say that the greater the demand for cooling is much greater than it should be on the surface to release the heat.

Fans Video card function

They are the best known and physically visible, called active cooling devices. It has moving parts that remove heat through a system similar to fans or electros in vehicles. They always produce some noise and are observed even in some external parts of computers.

These two devices allow you to lower the temperature to find a better function of the video card. They are compatible with any computer and even between devices with each other. Heatsinks extract heat while fans remove it.

Liquid refrigerant

There is a very advanced system that uses liquid cooling through water; It is used for video cards that maintains a fairly strong activity. The system is located near the chassis on desktop computers. It is very efficient, quiet and does not take up much space.

Feeding Video card function

The ways of receiving electrical energy in graphic card devices have been a bit varied, although they have not been a problem over the years, they are always at a considerable energy consumption level. The development of new technologies has caused the emergence of much greater consumption.

Power supplies are very powerful. Graphics cards can only consume levels below 75 W. But today there are higher consumption levels that have motivated a change even in its architecture. For example NVIDIA development cards come with PCle power devices that help to directly connect the power supply to the card.

The source in question has that PCle port where the current transmission passes through the motherboard and reaches the input connection of the graphics card. Of course, the function of the video card allows to distribute and manage in a balanced way all the energy quantity towards the various internal devices.

Some believe that the development of new technologies that is taking place with respect to graphics cards, may lead to the inclusion of direct power input ports, included in the cable that connects directly to the computer.

Old models of video cards Video card function

We already know the video card function, however, its performance was not always that way. Today we can see how these graphics cards keep managing other actions, so they help not only to increase the optimization of computers or video games, but also streamline important processes.

Video cards have had an evolution since their creation in the 60s, allowing their evolution developers to play with creativity to bring users excellent viewing conditions. However, the function of the video card evolved thanks to the old or disused cards that served to reach current technology.

Hercules Graphics Cards, (HGC)

Its name is due to the power and strength that it was thought could generate this card. However, it allowed it to become the standard model that the “hercules” company distributed in the first computers in 1982. Although it did not have the frequent BIOS routines.

The company that implemented its use was IBM, these cards have a resolution of just 720 x 348 pixels with a 64 Kb of memory monochrome screen. The RAM of the card was only to create references in each one of the points of the screen and to obtain the image. It used only 1 bit x 720 x 348 pixels, with a frequency of 50 Hz. The configurations were drawn in so-called matrices.

Color Graphics Adapter (CGA)

This color graphics adapter has been on the market since 1981 and was offered by IBM. It was an important element for the time in terms of monitor and screen development. I had matrices close to 8 x 8 dots on 25 row and 80 column screens. The characters are represented as underlined and it had a memory of 16 Kb. It was compatible only with RGB monitors and some derivatives, the graphic mode had a resolution of 640 x 200 pixels.

It was a bit superior to many video cards and allows to connect in a faster way the two existing points in the grids that have the monitors for connection. The color was of the digital type and had 3 bits for intensities, distributed in three phases. With this, 8 colors of two different intensities were achieved.

Despite being very popular, he had a deficiency in those teams. Eventually the “snow effect” appeared, which consisted of the appearance on the screen of white dots similar to snow. They were of an intermittent type that distorted the image, some computers bring the adapted BIOS where you can select the elimination of that fault.

Monochrome Display Adapter, (MDA)

It was one of the first monochrome type display adapters launched by the IBM company in the early 80s. They had a 4 Kb memory and it was an exclusive card for TTL type monitors. These types of graphics were best known for their green and amber color characteristics.

They never had graphics and the resolution could only reach 80 x 25 pixels, serving only for small characters. Neither could any type of configuration be carried out. But for their time they greatly helped many companies to solve various operations.

The MDA uses the video controller to read the ROM memory, sending the information in series that allow the opening of processes to be displayed on the screen through lines. The information and data processing was limited exclusively to the elaboration of lines of text and numbers.

Graphic developers

Many programmers know that working with graphics cards is a bit tricky. The installation and programming of them requires special knowledge, for those who are starting in the world of computer programming, we recommend using the following devices that allow a more efficient video card function through a more user-friendly installation .

Video cards require an application programming interface (API), which is complex and defining for these devices to operate efficiently. Let’s see then which video cards are best suited.

  • OpenGL is one of the most current and modern interfaces created by the Silicon Graphics company at the beginning of the 90’s. It is a free free application and it applied to many platforms. It is specifically aimed at CAD, Virtual Reality, or video simulation applications; it is free, free and multiplatform.
  • Direct3D is an application that is taking possession of the video card application markets, it was released in 1996 and is included in the work package and DirectX is used only for the Windows operating system in all its versions. It is currently one of the most used worldwide.

It can be purchased through Google Play applications or other application store platforms. It has reliability in the programmers and it is a form of development that is integrated into the software

Who designs and assembles them?

Today there are many companies that manufacture and assemble this type of device. However, some only dedicate themselves to developing the function of their video card as it was conceived in the early 60’s. Although their structure is totally different, these new video cards maintain an important efficiency.

The most important are three companies that hold 70% of the absolute market for video cards. We also have other companies dedicated to the design, manufacture and assembly of GPUs, these are NVIDIA, INTEL and old AMD ATI, which developed a large number of video cards in the 80s, but let’s see each one.

However, it is important to know that not all companies design, manufacture and assemble all GPUs and video cards, each one fulfills a specific function and for example other companies are in charge of assembling and manufacturing.

  • GPU designers, in this group are the most important such as INTEL, NVIDIA and AMD. In the case of INTEL, it is also responsible for designing integrated motherboard chip cards.
  • GPU manufacturers, we have some companies that do not design cards or chip devices, but are only responsible for manufacturing the devices based on the main parts, they offer it new as a final product. These companies are TSMC and Globalfoundries Matrox and S3 Graphics, the latter two with a slightly reduced market.
  • Assemblers include those that work directly with manufacturers of self-designed cards. This causes cards with the same chips to have different connections based on performance, especially graphics cards modified from the factory.

Although similar models have different names. However, the assemblers maintain some models with the same names and even the manufacturers also maintain this concept. Among them we have AMD and NVIDIA. Those who have video card models with similar names and even with very similar operation.

In this group are the models “CLUB3D”, “GIGABYTE” and “MSI”, certain differences can be found since it seeks with its competition to establish certain differences. Other models like “POWERCOLOR” at AMD represent the “EVGA” model at NVIDIA.

We also have models like “GECUBE” manufactured by AMD is similar to the “POINT OF VIEW” model from NVIDIA. AMD’s “XFX” card represents “GAINWARD” in NVIDIA, on the other hand “SAPPHIRE” is in AMD what “ZOTAC” is in NVIDIA.

Some models already patented cannot use the same names, the similarities in the names affect video cards that are a little older but are still manufactured in the world, for lower-cost computers.

Visual effects

The final result of the amplified process that makes up the function of the video card is manifested when the definition of the card is observed on the screen. We then observe diverse screen resolutions and splendid graphics when a video card has an incredible performance.

It is the same with video games, Thursdays are delighted when they can have fun and participate in video games where the images are of unsurpassed quality. Likewise, the benefits for Virtual Reality and 3D effects are always determined by the quality and efficiency of the video card.

These images and visual effects are created entirely by the video card function. But not only visual effects are generated, video cards can also generate resources such as the following:

  • Shading, It is a form of pixelation that allows placing various effects at vertices that increase the lighting and character of the figure, with this form good lighting, real natural phenomena, almost real surfaces and textures are also achieved.
  • Rendered, it is a form of execution of high dynamic range called HDR. Which is a very modern technique that allows to represent a range of intensity levels similar to real scenes. This effect allows you to observe direct light and shadows that are almost the same as reality. It has its predecessor in the common gloss and does not allow edge smoothing.
  • Sub Staging, allows you to make adjustments to avoid staggering or the presence of saw-like edges, very similar to pixelated ones. This effect allows considering the representation of curves and inclined lines in frontal spaces. Sometimes users confuse them with pixelation.
  • The focus of movement and depth, are two types of blurred effects that help to improve the reality of the images, it is generated when there is even a moving object. On the other hand, the depth effect is a type of blurred image that allows an object or figure to be distant.
  • Textures are a type of technology that is included in video cards. Allows you to add surface details in some models that modify objects and figures. This effect does not increase the difficulty of the same figures.
  • Flicker, this type of effect helps to consider the effect that is created by light sources in a camera lens. It is very efficient for some situations and especially in video games.
  • Specular reflection appears on almost all video cards and is also called the “Fresnel Effect”. It generates a mirror image that is reflected in an object according to its position on the screen, however the effect increases when the object is at a more increased angle.
  • Tessellation is a way of implementing the position of polygons in order to create geometric figures. The purpose of this technology is to ensure that the figures themselves do not look so flat.

Video card failures

Sometimes the expansion of the video card in order to find a better execution speed can cause some problems when carrying out some activity on the computer. To expand the power and function of the video card it is important to take into account a few things.

Knowing a little about the operation of the equipment model, year and manufacturer can help you learn more about solving problems that may occur suddenly. It is not convenient to adapt a higher power to the video card without knowing the characteristics of the computer.

When hardware is introduced to the equipment, it is most likely that some kind of problem sounds with the computer and especially with the video card. This problem can be solved when the symptom and the problem that the computer shows and that the card begins to manifest is known.

Like many devices. The function of the video card begins to fail when some symptoms are seen on the screen that may even damage another device in the computer and even the memory.

The operation sometimes also obeys the Driver updates. But let’s see what those symptoms are. Coming from somewhere or directly when a video card is working with problems.

Appearance of objects on the screen.

This situation can occur when at any time we see various artifacts appear on the screen for no reason, without knowing why they suddenly appear and disappear. The image is distorted and its sharpness is lost, this can happen because the card is not processing the desired process.

The point is that 3D objects deform and lose their configuration. In a way that can represent a problem that is reflected through an unavoidable symptom. Then the function of the video card is poor and it is immediately recommended to make the necessary adjustments or replace it.

Much fan noise

There may be the case where the fan is damaged. This situation can generate an uncomfortable noise in the equipment. So it can also create temperature rise on the video card.

The problem can occur when you turn on the computer or even at any time during its routine operation. It is important to remember that these devices have a useful life of a few years, the recommendation is to replace them immediately.

Driver problems

It may happen that the screen suddenly goes black for a few seconds for no reason. Then after a few seconds the computer turns on again and information related to the update of the drivers appears, so the computer must be restarted.

There are two ways to avoid this problem; first if it happens again it is for reasons that the video card is presenting failures. Then if you use the equipment for simple purposes only to prepare some documents and connect only to the internet. Proceed to disable automatic software and driver updates.

Lastly, if the problem continues immediately, call your computer technician for an immediate check-up. Try to avoid that the problem can be taxed by omission or carelessness.

Black screen

Sometimes it usually happens that the screen goes dark and goes completely black. But this time the screen does not turn on and does not show any information. what is recommended is to request the change of the card integrated in the motherboard. However, you can try a cheaper video card to really know if the problem is coming from there.

GPUs determine the function of the video card, however performance is determined specifically by bandwidth. The compatibility of video cards with the computer or operating system can also cause problems in the function of the monitor.

The way the cards are made may determine that some of them can be manufactured with certain limitations. In other words, each elaboration and manufacture of the video cards are only guaranteed by the manufacturing company. This, however, does not guarantee that the chips and other elements that allow the assembly of the card, can be the most optimal.

For this reason, some failures can be generated at the time of manufacture and assembly. The designs do not interfere with factory failures; so it is in the hands of the assemblers and manufacturers, to guarantee the reliability of the product. Some even have problems of adaptation and compatibility with operating systems.


To avoid a video card function breakdown it is important to know some simple solutions. This allows you to alleviate the problems and really know what is happening with the monitor or the video card.

Update drivers

It is a way of trying to solve certain casualties that happen on occasions, with unexpected closure of programs, unnecessary payments, black screen among others.

It is important to know that not updating the drivers can lead to a configuration problem. Some devices are designed to be updated from time to time. If for any reason the drivers have been updated. Look for the old drivers and update them.
