o If the message opens after a software program is opened, such as when starting a
game, the software is forcibly changing the display resolution to a mode that is
not supported by the computer and monitor. Do not use the software or change its
video settings.
o If the message opens after certain period of time when the computer is not in use,
the problem is most likely being caused by a screen saver. Turn off the screen
saver to see that the problem no longer continues.
Startup screens display, but the message opens before the Windows desktop opens
After turning on the computer, a few initial startup screens or text can be seen as the computer
starts. However, the Windows desktop never opens. Instead, a message about signal opens from
the monitor.
When this happens, the display resolution used by Windows has probably been set to a resolution
that cannot be used by the monitor. Use the following steps to see if the monitor can display
screens from safe mode:
1. Cycle the power on the monitor as follows:
1. Turn off the monitor. The power light on the monitor should be off. Leave the
computer turned on.
2. Unplug the power cord.
3. Wait 5 seconds.
4. Plug in the power cord.
5. Press the power button on the monitor to turn on the monitor.
One of two things happens:
The image from the computer displays on the monitor and you can use the
computer again. This indicates that the monitor was unable to detect that
the computer had awakened from suspend mode. Turn the monitor off
when it is not being used or disable suspend mode on the computer. For
some computers, updating the BIOS can correct these types of suspend
problems.
OR
The power light on the monitor comes on but the screen displays one of
the messages again. The monitor is not receiving a video signal from the
computer that it can detect and use. Continue using these steps.
2. If the computer is on, wait until the hard drive activity light on the computer is not lit and
then press and hold the Power button on the computer case until the computer turns off.
3. If the monitor has a factory reset or restore option, set it. Press the Menu button on the
front panel and select Factory Reset.
4. Wait 5 seconds and then turn on the computer by pressing the Power button again.
5. Adjust the Windows display resolution to a setting that is compatible with the monitor.
