User's Guide
Solution
Make sure the Power button is illuminated (aqua or amber light), 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 "Setting Up the Monitor" for more information.
Press a key on the keyboard or move the mouse to turn off the screen-blanking utility.
Check if your monitor and computer support HDCP.
Refer to High-Content Digital Bandwidth Protection or http://www.hp.com/support
Activate the OSD by swiping the slider bar. Press the Auto/Adjust 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, or connect the monitor HDMI signal
cable to the HDMI 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 "Preset Video and High-Definition Modes" in Appendix B). 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 graphic card supports the optimal resolution.
Make sure the latest supported driver is installed for the graphic card. For HP and Compaq
systems, you can download the latest graphics driver for your system from:
www.hp.com/support. For other systems, refer to the Web site for your graphic card.
Ensure HDMI audio is selected as the main audio output in the operating system. To do so, click
Windows Start Button, and then click Control Panel. Click Sound, and in the Playback
tab, ensure the check mark is next to the HDMI output, and click OK.
