 * Microsoft Windows 95
 * Microsoft Windows 98
 * Microsoft Windows 98 Second Edition

SYMPTOMS
Plug and Play detection for non-Display Data Channel (DDC) monitors is not supported in Microsoft Windows. You must manually install the monitor by selecting the appropriate driver from a list of those available in Windows 95. If a driver for your particular monitor is not listed, contact the monitor's manufacturer for the necessary drivers.

CAUSE
DDC is the Plug and Play standard for monitors. DDC monitors are designed to meet the Video Electronic Standards Association (VESA) standard that defines the DDC implementation. Windows automatically detects and enumerates a DDC monitor if it is connected to a display adapter that has also been designed to the DDC standard. Windows also installs the correct Setup information (.inf) file necessary for the display driver to set the proper refresh rate.

If the monitor is incorrectly detected as a VESA Plug and Play Monitor, it may not be listed in any of the existing .inf files. If this is the case, use the disk provided by the monitor manufacturer to install the appropriate .inf file. If the monitor manufacturer did not provide a disk, contact the manufacturer to obtain the correct .inf file.

RESOLUTION
To resolve this issue, enable the automatic detection of your Plug and Play monitor:


 * 1) Click Start, point to Settings, click Control Panel, and then double-click Display.
 * 2) On the Settings tab, click Advanced.
 * 3) On the Monitor tab, click to select the Automatically detect Plug & Play monitors check box.
 * 4) Click OK, and then click OK.
