Troubleshooting
Solving Common Problems
The following table lists possible problems, the possible cause of each problem, and the recommended solutions:
ProblemSolution
Power LED is not on. 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.
Screen is blank. Connect the power cord. Turn on the power.
Connect the video cable properly. See “Setting Up the Monitor” for more information.
Press a key on the keyboard or move the mouse to turn off the screen-blanking utility.
Screen is black or displaying 
at a lower resolution while 
displaying high-definition 
(HD) content.Check if your monitor and computer support HDCP.
Refer to High-Content Digital Bandwidth Protection or http://www.hp.com/support
Image appears blurred, 
indistinct, or too dark.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.
Image is not centered. 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.
Check Video Cable appears 
on screen.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.
Input Signal Out of Range 
appears on screen.Restart your computer and enter Safe Mode. Change your settings to a supported setting (see 
the table in “Preset Video and High-Definition Modes” in Appendix B). Restart your computer so 
that the new settings take effect.
Picture is fuzzy and has 
ghosting, shadowing 
problem.Adjust the contrast and brightness controls.
Make sure that you are not using an extension cable or switch box. We recommend plugging

							LCD Monitor Quality and Pixel Policy
The HP LCD Monitor uses high-precision technology, manufactured according to high standards, to help guarantee 
trouble-free performance. Nevertheless, the display may have cosmetic imperfections that appear as small bright or 
dark spots. This is common to all LCD displays used in products supplied by all vendors and is not specific to the 
HP LCD Monitor. These imperfections are caused by one or more defective pixels or subpixels.
■A pixel consists of one red, one green, and one blue subpixel.
■A defective whole pixel is always turned on (a bright spot on a dark background), or it is always off (a dark spot 
on a bright background). The first is the more visible of the two.
■A defective subpixel (dot defect) is less visible than a defective whole pixel, and is small and only visible on a 
specific background.
To locate defective pixels, the monitor should be viewed under normal operating conditions and in normal operating 
mode at a supported resolution and refresh rate, from a distance of approximately 16 inches (50 cm).
We expect that, over time, the industry will continue to improve its ability to produce displays with fewer cosmetic 
imperfections, and we will adjust guidelines as improvements are made.
For more information about your HP LCD Monitor, refer to the HP Web site at: http://www.hp.com/support
Power Cord Set Requirements
The monitor power supply is provided with Automatic Line Switching (ALS). This feature allows the monitor to operate 
on input voltages between 100–240Vv, 50/60 Hz, 1.5A.
The power cord set (flexible cord or wall plug) received with the monitor meets the requirements for use in the 
country/region where you purchased the equipment.
If you need to obtain a power cord for a different country/region, you should purchase a power cord that is approved 
for use in that country/region.
The power cord must be rated for the product and for the voltage and current marked on the product’s electrical 
ratings label. The voltage and current rating of the cord should be greater than the voltage and current rating marked 
on the product. If you have questions about the type of power cord to use, contact your HP-authorized service provider.
A power cord should be routed so that it is not likely to be walked on or pinched by items placed upon it or against it. 
Particular attention should be paid to the plug, electrical outlet, and the point where the cord exits from the product.
