If you have multiple monitors connected to your computer, a horizontal line may continually scroll down the screen of one or more monitors.

This behavior can occur if your monitors are too close to a fluorescent light source, or you are using an unshielded monitor, and you place it too close to another monitor.

To work around this behavior, use either of the following methods:

•	Move the unshielded monitor away from any monitors or fluorescent light sources it interferes with.
•	Place a shield (for example, a cookie sheet) between the unshielded monitor and any monitors it interferes with. For additional information about how to shield an unshielded monitor, please contact the manufacturer of the unshielded monitor.

Most early monitors are unshielded, which means they do not confine the magnetic field they emit. Later monitors are shielded so that most of the magnetic field they emit is confined within the monitor. If you place an unshielded monitor too close to another monitor, the magnetic field emitted by the unshielded monitor may interfere with the other monitor.

Windows 98 supports the use of multiple monitors to expand your desktop area. To use multiple monitors, you need a supported Peripheral Component Interconnect (PCI) or Accelerated Graphic Port (AGP) video adapter for each monitor that is connected to your computer, and DirectX 5-compliant video drivers.

For information about how to use multiple monitors in Windows 98, click Start, click Help, click the Index tab, type multiple, and then double-click the "Multiple display support" topic.
