All computers are connected to some type of display whichis
called a monitor . Monitors are available in many different types and sizes
(generally 12 to 21 inches diagonal screen size). The monitor is a part
of the computer video system. To understand how to obtain a good screen
image, we need to look at the complete video system. It includes three
elements:
-
The graphics card (also called the video card or video adapter). It is
an expansion card, which generates electric signals to the monitor.
-
The monitor itself, which is connected by a cable to the video card.
-
A device driver which Windows 95/98 uses to control the video card, to
make it send the correct signals to the monitor.
These three elements must be fitted and matched to achieve quality images.
Even the finest and most expensive monitor will only render mediocre images
if it is connected through a low quality video card. All video cards depend
on the right driver and proper settings to function properly – otherwise
the card will not perform well.
Fast development
The video system has developed as explosively as the rest of the PC during
the last 10 years. These improvements have occurred in different areas:
-
The monitors – both the tubes and the electronics continue to improve.
They render better and better images - sharper, with better resolution
and better colors.
-
New monitor types are arriving on the market. The flat TFT screens are
on their way to the stores. In a few years, they will become the new screen
standard.
-
The video cards are getting faster. They can deliver better images, which
the new monitors are capable of producing. The user gets more tuning options.
New RAM types and the AGP bus will increase speed. Video presentation and
3D games are other areas of development, which will change the video card
standards.
The video system is a sub system in the PC, with its own technological
development. At the same time, monitors and video cards are areas, where
manufacturers and dealers often cut corners. As an ordinary user, you can
improve your screen images significantly with careful planning. That holds
true when you buy your PC - you must select your video system carefully.
It also holds true for existing video systems, where better drivers and
software optimizing can help produce the optimal screen image. |
