Solution
Make sure the Power button is on, and the power cord is properly connected to
a grounded power outlet and to the monitor.
Select Management in the OSD menu, and then select Bezel Power LED. Check
if the Bezel Power LED option is set to Off and, if so, set to On mode.
Connect the power cord. Turn on the power.
Connect the video cable properly. See
information.
Press a key on the keyboard or move the mouse to turn off the screen-blanking
utility.
Press the Auto/Select button on the monitor front panel. If this does not correct
the image, press the Menu button to open the OSD menu, and adjust the
brightness and contrast scales.
Press the Menu button to access the OSD menu. Select Image Control, and then
select Horizontal Position or Vertical Position to adjust the position of the
image.
Connect the monitor VGA signal cable to the VGA connector on the computer, or
connect the DVI-D signal cable to the DVI connector on the computer. Be sure
that the computer power is off while connecting the video cable.
Restart your computer and enter Safe Mode. Change your settings to a supported
setting (see the table in Recognizing Preset Display Resolutions on page
Restart your computer, so that the new settings take effect.
Adjust the contrast and brightness controls.
Make sure that you are not using an extension cable or switch box. We
recommend plugging the monitor directly into the graphic card output connector
on the back of your computer.
For VGA input, the auto-adjustment feature might fix this problem.
Make sure the graphics card supports the optimal resolution.
Make sure the latest supported driver is installed for the graphics card. For HP
and Compaq systems, you can download the latest graphics driver for your
system from: http://www.hp.com/support. For other systems, refer to the Web site
for your graphics card.
