We will discuss some of the main functions of a Graphics Card, and the options that you can consider in fixing troubles with unknown graphics card driver.
Functions of a Graphics Card
Graphics card is also known as video card, video adapter, graphics accelerator card, and display adapter. Some of its main functions include accelerated rendering of 3D scenes and 2D graphics, video capture and decoding, TV/Video output, ability to connect multi-monitors, and the most demanded at our present time is its ability to support the features of high-end PC games.
Graphics Card is mostly known and classified as an expansion card, but most computers or laptops also come with onboard Graphics Card. Both of these types of Graphics Card provide the main function of rendering graphics/display on the computer’s monitor. On the other hand, the performance of a PC that is only using an onboard Graphics Card is much slower than a PC equipped with an expansion card. Another advantage of using an expansion card is that you can always replace it with a newer and better one.
Graphics Card is very vital for you to execute programs or applications on your computer, such as browsing the Internet (watching videos, online applications such as Google Earth, et al), editing pictures using Microsoft Paint or other software such as Photoshop, playing games (basic PC games to high-end 3D Games,) and many more.
