How Does Video
Memory Work?
The image on the screen is made up of tiny dots called pixels. Each pixel has a color, and every color is represented by a
value. Video memory stores the color value of every pixel.
The screen resolution determines how many pixels make up a displayed screen. The number of pixels required is
typically very large (for example, 300,000 pixels for a standard VGA screen with a resolution of 640
×
480).
How Much Video
Memory Does My
Computer Have?
The amount of video memory that your computer has depends on the particular model that you have. You may have 1 MB
or 2 MB of video memory installed on the system board. To find out how much video memory is installed, from Windows
95 select the Display icon from the Control Panel and click the Settings tab, then select the Advanced Properties button.
Why Increase the
Amount of Video
Memory?
Increasing your display resolution will increase the total number of pixels needed to define an entire screen. Similarly,
increasing the number of displayable colors will increase the amount of data required to display the pixels. Increasing
either of these parameters will increase your requirement for video memory.
More video memory makes it possible to obtain higher screen resolutions, higher refresh rates (the frequency at which
the screen’s horizontal lines are recharged), and many more colors for existing resolutions.
How Much Video
Memory Can I Add?
If your computer has 1 MB of video memory on the system board, you can increase it to 2 MB. To find out how much video
memory is installed, from Windows 95 select the Display icon from the Control Panel and click the Settings tab, then select
the Advanced Properties button.
