■Make sure that the monitor is plugged in and turned on. If the monitor is turned on, the power LED should be lit.

■Adjust the brightness and contrast controls to the center position.

■Make sure that the monitor cable is connected to the video port on the back of your computer.

■Check the cable for bent or damaged pins.

■Reinstall the device driver.

■Connect a monitor that you know works to your computer.

The color is not uniform

Make sure that the monitor warms up for at least 30 minutes before making a final judgment about color uniformity.

Make sure that:

■Non-shielded speakers are not placed too close to the monitor.

■The monitor is not positioned too close to another monitor, electric fan, fluorescent light, metal shelf, or laser printer.

■You demagnetize the screen using the monitor’s degauss feature. For more information on degauss, see your monitor’s documentation.

Why is there a horizontal line or wire visible across the monitor screen?

Your monitor may use a thin damper wire, located approximately 1/3 of the way down from the upper screen edge and 1/3 of the way up from the lower screen edge, to stabilize the internal aperture grille. These wires are most obvious when the monitor displays a white background. The aperture grille allows more light to pass through the screen for brighter colors and greater luminescence. The damper wire is a critical part of the overall monitor design and does not negatively affect the monitor's function.
