A Troubleshooting Solving Common Problems The following table lists possible problems, the possible cause of each problem, and the recommended solutions: Problem Power LED is not on. Screen is blank. Image appears blurred, indistinct, or too dark. Image is not centered. Check Video Cable appears on screen. Input Signal Out of Range appears on screen. Picture is fuzzy and has ghosting, shadowing problem. Unable to set the monitor to the optimal resolution. Unable to hear audio from built-in speakers. 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 "Setting Up the Monitor" for more information. Press a key on the keyboard or move the mouse to turn off the screen-blanking utility. Press the Auto/OK button on the monitor side 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. 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 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. 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: www.hp.com/support. For other systems, refer to the Web site for your graphics card. Do the following: ■ Ensure the source signal is good by using headphones at the source. ■ Press the Menu button to access the OSD menu. Select Management, and then select Volume to adjust the volume. ■ Turn up the volume with the side panel Volume button. ■ Ensure speaker volume is not muted or too low: Click the Windows Vista start button™ , Control Panel, and Hardware and Sound. Under Audio Devices and Sound, click Adjust system volume. Under Main Volume, move the slider up. User's Guide A-1
