Here's what to do:
1. Make sure the monitor controls are adjusted correctly. Refer to the
documentation that came with your monitor for information about the
monitor controls.
2. Move the monitor away from any equipment that might cause magnetic
interference; for example, other monitors, audio speakers, or microphones.
(Some models of the computer come with microphones and speakers, which
are shielded to prevent magnetic interference.) Turn off the monitor, wait 30
minutes, and then turn the monitor on again.
3. Select a new video device driver.
Adjust the monitor controls. For instructions, see the documentation that came
with the monitor.
While your monitor resolution may allow you to change the font size, some
programs do not support large fonts. Large fonts may cause words to appear
cut off or pushed together. Check the settings in Display Properties. Make sure
the font size selected is small fonts.
1. Make sure the monitor cable is correctly and securely connected to the
system unit.
2. Make sure the system unit is turned on.
3. If available, connect another monitor to your system unit. If the problem is
corrected, something may be wrong with your monitor.
1. Select lower resolution, fewer colors, and higher refresh rates.
2. If your monitor is located close to another monitor, move them farther apart.
3. Change the video device driver in your software program.
