Verify the power source by plugging in an appliance that you know works.
If you have not already done so, plug the monitor directly into an electrical outlet,
bypassing any power protection devices, power strips, and extension cables to
verify that the computer turns on.
If the power light is not on, check for a bad power cable by turning off the com-
puter and swapping the monitor and computer power cables.
Perform the monitor self-test as described in the documentation that came with
your monitor.
If the picture quality is poor, perform these checks:
Rotate the monitor to face a different direction. If the picture changes, see “Envi-
ronmental Factors,” found earlier in this chapter. Monitors are particularly
susceptible to EMI, which causes colors to fade and blend.
If the orientation of the computer affects the picture quality, check the documen-
tation that came with your monitor for information on adjustments.
Degauss (demagnetize) the monitor as described in the documentation that
came with your monitor.
If you changed the resolution or refresh rate settings of the monitor, return the
monitor to its manufacturer’s recommended settings (see the documentation
that came with your monitor).
Turn off the computer, and examine the video-interface cable connector for bent,
pushed in, broken, or missing pins. Check the documentation that came with
your monitor for additional information.
NOTE: Some missing pins may be normal for your monitor; check the documen-
tation that came with your monitor.
Remove any video extension cables, reseat the monitor’s video-interface cable
connector, and securely tighten the captive screws. Then reboot the computer.
Perform the monitor self-test as described in the documentation that came with
the monitor.
If another monitor or computer is available, try swapping monitors between
computers.
Move the computer and the monitor to another room.
If you completed the basic monitor checks and suspect a problem with the video, per-
form the following checks:
Click the
Start
button, point to
Settings
, and click
Control
Panel
. Double-click
the
Display
icon, and click the
Settings
tab. Try different
Color palette
and
Screen area
settings.
Change the display type to standard video graphics array (VGA) as follows:
Restart the computer. Press <Del> when you see the
6WDUWLQJ:LQGRZV
message, and then select
Safe
Mode
from the boot manager screen.
