Troubleshooting
The computer is running but there is no picture
■ 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.
The text on the display is dim or difficult to read
■ Adjust the brightness and contrast controls.
■
Use the monitor degauss feature (see your monitor documentation) or turn off your
computer and monitor, leave them off for at least a half hour, then restart your
computer.
■ Change the display settings.
