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.
