Display adapters are pieces of hardware that generate video information that is displayed on the computer monitor. The most common display adapter for a computer is the video card. Knowing the details of your display adapter will help you judge what kind of software your system is capable of using and let you identify the manufacturer of the device. You can access this information from within Windows.
