Identifying monitor conditions

    • For the x22LED/ x22LEDc monitors: 1920 x 1080 @ 60 Hz
    • For the x23LED monitor: 1920 x 1080 @ 60 Hz
  • No Signal: Indicates the monitor is not receiving a video signal from the computer on the monitor video input connector. Check whether the computer or input signal source is off or in the power-save mode.
  • Auto Adjustment in Progress: Indicates the auto-adjustment function is active and in process.

Troubleshooting

The following table lists possible problems, the possible cause of each problem, and the recommended solutions.
Problem
Solution
Power LED is not on.
Make sure the power cord is connected to a grounded power outlet and to the monitor.
No Plug and Play.
For the Plug and Play feature of the monitor to work, you need a Plug and Play compatible computer and video card. Check with your computer manufacturer.
Check the monitor video cable and make sure none of the pins are bent.
Make sure the HP monitor drivers are installed.
Picture is fuzzy and has ghosting and shadowing problems.
Adjust the contrast and brightness controls.
Make sure you are not using an extension cable or switch box. HP recommends plugging the monitor directly into the video card output connector on the back of the computer.
For VGA input, use the auto-adjustment feature to try to fix this problem.
Picture bounces and flickers, or a wave pattern is present in the picture.
Move electrical devices that might cause electrical interference as far away from the monitor as possible.
Use the maximum refresh rate the monitor is capable of at the resolution you are using.
Monitor is stuck in “Active Off-Mode.”
Check the computer:
  • The computer power switch should be in the On position.
  • The computer video card should be snugly seated in its slot.
  • Make sure the computer is operational by pressing the Caps Lock key on the keyboard while observing the Caps Lock LED. The LED should turn on and off.
Make sure the monitor video cable is correctly connected to the computer.
Inspect the monitor video cable and make sure none of the pins are bent.
“Out of Range. Set Monitor to [your monitor's optimum resolution]” is displayed on the screen.
Restart the computer and enter Safe Mode. Change the settings to the recommended resolution. Restart the computer so that the new settings take effect.
Missing one of the primary colors (red, green, or blue).
Make sure the monitor video cable is correctly connected to the computer.
Inspect the monitor video cable and make sure none of the pins are bent.

Horizontal or vertical disturbances on the screen
Adjust CLOCK and Phase or press the Auto button to display the ideal setting. To optimize the screen performance for VGA input, use the Auto button on the monitor and the auto-adjustment pattern software utility on the CD provided. For DVI input, adjust the video graphics card installed in the computer.

Power-saver feature

When the monitor is in normal operating mode, the Power light is blue and the monitor uses the normal watts of power. The monitor also supports a reduced power state which occurs if the monitor detects the absence of either the horizontal sync signal or the vertical sync signal. When detecting the absence of these signals, the screen becomes blank, the backlight turns off, and the Power light turns amber. When the monitor is "awakened," a brief warm-up period occurs before the monitor returns to normal operating mode.
The power-saver feature must be activated on your computer for this feature to work. Refer to your computer documentation for instructions on setting energy-saver features (sometimes called power-management features).
note:
The energy-saver feature works only when the monitor is connected to a computer that has energy-saver features.

Tips and recommendations

  • Unplug your monitor from the wall outlet before cleaning. Clean the monitor plastics with a clean cloth dampened with water. Do not use liquid cleaners or aerosol cleaners. Clean the monitor screen with an antistatic screen cleaner.
  • Do not open your monitor cabinet or try to service this product yourself. Adjust only those controls that are covered in the operating instructions. If your monitor is not operating correctly, or has been dropped or damaged, contact your HP authorized dealer, reseller, or service provider.
  • Use only a power source and connection appropriate for this monitor, as indicated on the label or back plate of the monitor.
  • Never disconnect the monitor by pulling the cord.
  • Turn your monitor off when not in use. You can substantially increase the life expectancy of your monitor by using a screen saver program and turning off the monitor when not in use.
  • When removing the monitor base, place the monitor face down on a soft flat area to prevent it from getting scratched, defaced, or broken.
  • Burn-in image damage might occur on monitors that display the same static image on the screen for a prolonged time. To avoid burn-in image damage on your monitor, always start a screen saver or turn off the monitor when it is not in use for a prolonged period.
