Far from being a simple component of the central unit, the graphics card also plays a role in the performance of the screen. With the latest generation technologies, graphics cards are the subject of ever-increasing attention.
Also, before getting one, it is advisable to compare the characteristics of the different models through a comparative study, based on the analysis of the opinions and experiences of consumers who participated in the test.
What is the graphics card?
It is a constituent element of the central unit of electronic devices provided with a visual interface. The graphics card is used to transcribe the image on the screen. This centrepiece is responsible for the display and the quality of the image.
It has properties that allow it to decipher high definition visuals without altering their qualities. It is found in computers, televisions, video games … The graphics card guarantees a faithful rendering of the nuances and colors of an image.
How does the graphics card work?
Most of the big companies like Nvidia GeForce graphics card functions as a conversion module. Through the pixels, it converts the numerical values into graphic values that can be read by the screen.
This operation is carried out by means of graphic calculations which allow the image to be synthesized while offering the best rendering of shape, colour and texture. The graphics card is equipped with a GPU graphics processor which is the command centre.
Thus, the weight of the visual information must determine the power of the graphics card to be used. To the image processing, certain standards contained in the video bios apply .
This same bios therefore constitutes an excellent database for the comparison of the various characteristics between the images.
Finally, in general, the graphics card has an operation which can be either independent, as an additional element, or be connected to the motherboard of the central unit in which it is integrated.
The properties of the graphics card also called video card, including the processing of visual data (image, video, video games) and their presentation on the screen. They cover the needs of video editing, namely the encoding process and image rendering. Some people may face Nvidia GeForce scanning experience failed error which can be easily solved by troubleshooting GeForce Experience error code 0x0001.
The graphics card also governs the creation of 3D images, an activity requiring extremely precise visual data. It is she who manages the display of the Windows system (its windows, its icons, its desktop, etc.).
Benefits and areas of application
- It guarantees a good definition of the image, both in its highlighting and in its details, for an optimal result.
- It facilitates image processing and speeds up the video rendering process.
- It offers exceptional virtual reality.
- It offers additional memory space.
What types of graphics card are there? What are their advantages & disadvantages?
All graphics cards have the same characteristics, however they are distinguished by their connectors, some of which have more advantages than others. We can categorize the cards into 4 categories according to their parameters connection, which are important elements of comparison:
1. The VGA graphics card
The “video graphic array” is one of the first versions of graphics card. Its connection system is one of the oldest. With a blue color , the VGA card has standards for image and video management.
Comparative consumer tests tell us that this card provides the best image quality . But also that it has many limits, concerning both video and 3D modeling and fan noise.

2. The DVI graphics card
The DVI or Digital Visual Interface is a white card. It succeeded the VGA card. This card provides improvements in image processing and display, for better performance.
This development is particularly remarkable for videos or games. If your video card and your screen have this type of connection, prefer it to VGA ! All the comparisons are in its favor. User reviews tend to recommend this card for cartoons and modeling, although the comparisons still point to limitations in image definition and thermal regulation.
3. HDMI graphics card
The HDMI (High Definition Multimedia Interface) card tops all comparisons. On the one hand, its connectivity is universal. On the other hand, it provides the image with a high definition format . With HDMI, you get the best out of a TV screen. The only negative point of this card is its slightly excessive cost.
4. S-Video
This graphics card is able to serve different screens. It has several connectivity inputs, intended for different interfaces but having the same central unit. The users who have used it and subjected to a comparative test find it advantages: it is practical, allows to increase the visibility and to keep a better control of the image.
The multi-screen card has won favorable reviews because of its main advantage, which is that it can be connected to several interfaces. Note, however, that this card has one major flaw : its high price.
