Display Drivers

A display driver is a software interface that enables Windows to communicate with the hardware video adapter. Windows provides several standard display drivers that work with any video adapter; however, many Windows users install a custom driver provided by the manufacturer of the display adapter in their computer. These custom drivers offer more colors and higher resolutions than are available with the standard Windows display drivers.

When a customer cannot start a setup properly, it is often due to a problem with a custom display driver. The following symptoms usually indicate that the problem is the display driver:

•

The setup starts but does not appear on the screen.

•

The system hangs when the setup attempts to display a bitmap (.bmp) file.

•

The screen display malfunctions when the setup attempts to fade in a bitmap.

When a customer reports one of these symptoms, determine which video driver is installed in their system. Suggest that they install a standard Microsoft Windows VGA driver and then run the setup again. If necessary, the customer can always return to the non-standard driver after installing your software.
