is increasing in graphic intensity. Even mundane business software uses
icons, charts and animations. When you add 3D games and educational software
to the equation, one can see that there is a crunch in bandwidth for graphical
information. With newer software and games getting much more graphics
intensive, the PCI bus is maxed out. In fact, the PCI bus, once considered
very fast, can now be considered a bottleneck.
AGP Motherboard/Chipset Drivers
Not only do you need display drivers for an AGP graphics card, you also need drivers for your motherboard which enable AGP functionality for the motherboard chipset.
there AGP drivers on the Windows CD?
There are two types of chipsets available on a video card GPU and VPU.

Memory located on the video card, in some cases located on the motherboard that is accessible by the video and computer processor. With more video memory the video card and computer is capable of handling more complex graphics at a faster rate. Video card memory may be between 8 and 128MB of memory or higher.
There are various forms of memory SDRAM , DDR and DDR-II.
VGA stands for Video Graphics Array. It was introduced on April 2, 1987 by IBM, the same day it introduced the MCGA and 8514/A adapters. Although all three were advances for the time, only VGA became increasingly popular. VGA, although now more advanced, has become the standard for desktop video, leaving both the MCGA and 8514 in the dust.
IBM PS/2 systems contained the VGA circuitry on a single VLSI chip which was integrated onto the motherboard. In order for users to use the new adapter in earlier systems, IBM developed the PS/2 Display Adapter, or the VGA video card. This card contained all the circuitry needed to produce VGA graphics, and like all expansion cards, it plugged into a slot on the motherboard, via an 8-bit interface. In the light of advances, IBM has discontinued this basic VGA card, although many third party cards are available. Today, the VGA card is not much used, and usually serves as a "spare".
VGA offers clean images at higher resolutions. The standard VGA can produce as many as 256 colors at a time from a palette of 262,144 colors. The original VGA, though, had to be at a 320x400 resolution to display this amount of color. At the standard 640x480 resolution, it was only capable of 16 colors at a time. Also, VGA extends into the monochrome world. It uses color summing to translate color graphics into graphics using 64 different shades of grey. This, in effect, simulates color on a monochrome monitor. VGA requires a VGA monitor, or one capable of accepting the analog output of a VGA card.
VGA category of video card is really rather loosely named. It refers to
a group of video cards, all with roughly the same capabilities. It does
not refer to a specific card, like the VGA technically does. SVGA was
developed by third party companies in order to compete with IBM's XGA
and 8514/A display adapters. They probably thought it would be cheaper
to develop new hardware rather than try to adapt the new capabilities
onto the standard VGA card.
SVGA is much more advanced than VGA. In most cases, one SVGA card can produce millions of colors at a choice of resolutions. But, the abilities depend on the card and the manufacturer. Since SVGA is a loose term created by several companies, there is no actual standard to SVGA.
In order to create some standard out of the chaos of SVGA, the Video Electronics Standards Association (VESA) introduced a SVGA standard. This SVGA standard did not deal with certain methods of implementation of capabilities, but, instead, defined a standard interface called the VESA BIOS Extension. This provided programmers with one common interface to write for instead of trying to tailor their programs to work with several different SVGA cards, all different. All SVGA cards in use today comply to the VESA standard.
At first, the VESA SVGA standard was criticized, and manufacturers were slow to integrate it. At first, they distributed the extension as a program to be loaded each and every time you booted the computer. Finally, though, manufacturers integrated the extension as a part of their SVGA BIOS.Back to Top
To test the TV-out feature of your graphics card, turn off your computer. Then connect the S-VIDEO cable from your graphics card to your TV. If your TV does not support S-VIDEO, then you may need to purchase an “S-VIDEO to Composite” adapter. Once you have all the connections you need, connect your graphics card to your TV. Make sure there are no other devices in between, such as a VCR or switchbox. Then, unplug the PC monitor from your graphics card leaving only the TV connected to your PC. Make sure your TV is set to AUX or Line-In. Otherwise, your graphics card will not detect the presence of a TV. Turn on your PC. The system should automatically detect your TV and send the video signal to your TV. If it does display the video signal onto your TV but stops once you boot into Windows, it may simply be a driver issue.

used for digital LCD monitors; effectively eliminates the video noise
from digital-to-analog-to-digital conversion.
There are two types of DVI connectors DVI-D and DVI-I.
If the graphics card is already correctly installed on your PC, there are two methods for identifying which graphics card is on your PC.
The first method is for users running Windows 95/98/Me/2000/XP. To identify which graphics card is in your PC, follow these steps:
Turn on your
PC and let Windows load
For Windows NT4 users, once you are in Windows NT4, click on the START button -> Select Settings and then Control Panel -> Open up the icon labeled Display. This will bring up your Display Properties. Click on the "Settings" tab and it will show you the make and model of your graphics card.
The second method may not work for every PC. Generally, each time you turn on your PC, your system will display the make and model of the installed graphics card(s) on the top left corner for about three seconds. However, with some PCs, that information is replaced by your motherboard information or the logo for the company that assembled your PC. If that is the case, you may want to contact the maker of your PC for assistance in removing the OEM logo so that the information about the installed graphics card(s) will appear.Back to Top
