A video card is that device ( a loaded circuit board ) that determines the screen output or video display of the computer. It is also known as the graphics card, graphics adapter, display adapter or video adapter.
The video card is either installed directly on the mother board or in an expansion slot. The intended use determines which type to use.
What to check for when choosing a video card
1. Determine how the computer will be used. Is it for computer games or just for ordinary encoding?
There are different types of video cards for different uses.
2. RAM is resolution required to meet the video output needed.
The memory of a video card is very important for speed because it holds the common operands for the images. Since the video card can access its own memory faster than that of the mother board, the images are displayed faster.
3.Mother board and Video card format compatibility.
A mother board doesn’t support all kinds of video cards. Some mother boards only have the GPUs or graphics processing units which maybe adequate for an average business or home use but not applicable where more graphics capabilities are needed. A GPU is a video card’s own processing unit.
Mother boards may have the following expansion slots: AGP slots, standard PCI slots, 1xPCI EXpress slots, 16xPCI Express slots. Make sure the video card and the slot where it will be installed are compatible
The 16XPCI Express slot has compatibility with the most video cards, so it is advisable to buy this card for a new computer. The next newest slot is the AGP slot which came before 16xPCIExpress.
The least recommended slot is the PCI slot because there are only a few video cards compatible with it and most of them are the slow , expensive type.
4. TV output capability
Not all video cards have this capability. Be sure to check this out.
5. The fan on the video card must be working to prevent over heating of parts which slows down its performance.
6. Price- how much can you afford to pay?
The compatibility of components determine how the equipment functions. In the case of video cards, there is more need to check for compatibility due to the various models developed to meet various needs.
Incompatibility is expensive, for how will you install a video if it doesn’t fit in the expansion slot?
