Troubleshooting

The monitor is switched ON, but the Power LED indicator is
not lit and there is no display on the screen.
Check all the power connections and make sure they are
secure. If the monitor is plugged into a surge protector, make
sure that the surge protector is switched on.
Why do I hear a "humming" sound when I first switch on the
monitor?
The sound you hear indicates that the degauss function is
activated. Every time the monitor is switched on, it will go
through the degaussing process which helps eliminate any
purity problems.
How do I change the resolution the monitor displays?
The frequency and resolution displayed on a monitor is con-
trolled by the video card and operating system. The monitor
simply responds to the signal it receives from the video card
and is not able to change the resolution on its own. Most
video card manufacturers provide software drivers and utili-
ties that allow you to use different resolutions for different
applications. Please consult your video card manual or
dealer for more information.
The monitor is "plug and play," why do I still need to run the
graphics card utility to make adjustments on refresh rate in
different resolutions?
In order to fully utilize the plug and play feature, the com-
puter must be equipped with a plug and play (DDC2B) video
card and running with a Plug and Play capable operating
system (i.e., Windows® 98) or a separate utility program that
enables the plug and play function automatically.
