A graphics card is the part of a PC which enables the PC to convert logical info into viewable pictures or signals that may be viewed on displays like PC monitors, LCD or projectors. The central processing unit (CPU) sends info about image to the graphic card. The graphic card then processes the data and sends it to the monitor to supply the best possible viewable image supported by its specs. They also are known as video cards, graphic adapters and graphic controllers for example.

A graphic card has complicated functions. It is hooked up to the motherboard, monitor, processor, and memory and works in coordination with all of these parts.

Some graphic cards have further connections for Television , digital and analog cameras. Nowadays graphic cards are often available as integrated in the motherboards, but add-ons are also available.

There are plenty of kinds and brands of graphic cards. While selecting a graphic card, one should try the CPU speed. A graphic card is good only so long as the CPU speed can support its functions. One also needs to test whether specs of the PC fit with the graphic card. The directions of a graphic card decide the standard of image produced like the colours it can display, number of pixels and the like. For basic use of PC like typing, skimming or easy games, graphic cards integrated in the motherboards are quite acceptable. Sophisticated and high memory graphic cards are needed for high end gaming, fast net surfing for simple download of photos and designers with lot of 3-D work. Software games are also becoming complicated and 3D in nature and so are the graphic cards to support them. To upgrade, old graphic cards can get replaced by newer ones simply by anyone. In some graphic cards, there’s a chance of adding more memory without changing the card utterly.

So , what we see on a P. C. is really thanks to graphic cards. Without a graphic card, we might just be having a look at dots known as pixels. The blueprint of a graphic card ultimately decides what occurs to these pixels and the standard of the final output.
