Identifying monitor conditions

Special messages display on the monitor screen for the following monitor conditions:
  • Input Signal Out of Range: Indicates the monitor does not support the input signal because the resolution and/or refresh rate are set higher than the monitor supports. Recommended refresh rates are as follows:
    • For the w1858 monitor: 1366 x 768 @ 60 Hz.
    • For the w2338h monitor: 1920 x 1080 @ 60 Hz.
  • Monitor Going to Sleep: Indicates the screen display is entering a sleep mode.
  • Check Video Cable: Indicates a video input cable is not properly connected to the computer or monitor.
  • OSD Lock-out: When the OSD is locked, the warning message OSD Lock displays for 10 seconds.
  • No Input 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.


The following table lists possible problems, the possible cause of each problem, and the recommended solutions.

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.

Power-saver feature

When the monitor is in normal operating mode, the Power light is green.
The monitor supports a reduced power state which occurs if the monitor detects the absence of either the horizontal sync signal and/or the vertical sync signal. Upon detecting the absence of these signals, the screen becomes blank, the backlight turns off, and the Power light turns orange.

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.
