I can't get my icons and taskbar to center on my monitor. The start button is off screen to the left. How do I center everything so I can access them?

Press the OSD (On Screen Display) button on the monitor.
Use the UP/DOWN and LEFT/RIGHT buttons to navigate through the menu, to get to the "horizontal position" menu.
Press the OSD button to "select" that setting.
Press the LEFT/RIGHT buttons to "move" the image LEFT/RIGHT.
Press the OSD button to "apply" the new location.
Wait a few seconds, and the OSD menu should close itself.

When i press the power button to turn off monitor, i get a power button lockout message. how do i unlock the power button

I did not see anything regarding to the Power locked out function, may be it's time to call HP. Please post back what you find out from HP.
I look at HP WEBSITE:

Locking OSD settings
When the OSD is locked, settings cannot be changed in the OSD menu. The OSD functionality is enabled or disabled by pressing the Menu button and holding it for 10 seconds. Upon disabling the OSD, an OSD Lock-out message is displayed for 10 seconds. When the OSD is locked and an OSD menu button is pressed, the OSD Lock-out message is displayed for an additional 10 seconds. When the OSD is locked, pressing the OSD menu button for 10 seconds unlocks the OSD and displays the main menu. 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.

OSD Locked pop menu


You must reset the on screen display in the menu. Hold down the Menu button for at least 60 seconds. A menu list will appear on your monitor screen. Using the adjust button, press the arrows to enter the menu. Scroll down to the Reset section.
On the right side of your screen, you will see an alternating Yes/No choice. When the Yes message flashes, press the Ok button. The menu should be reset and the flashing OSD control message should disappear.
I hope it helps.

All the best.

Osd lockout? How do I get the on screen display unlocked?

OSD Lockout prevents changes being made to the monitor through the use of the front panel buttons. When the OSD is locked, pressing a button from front panel displays OSD Lock-out for about 10 seconds. You can quickly remove the OSD Lockout message by pressing a front panel button again. To unlock the OSD, press and hold the Menu button until the Main menu displays, about 10 seconds. To lock the OSD, press and hold the Menu button until an OSD-Lockout message displays, about 10 seconds.

The problem of OSD Menus popping up automatically are usually caused due to a faulty switch in the Menu button which is getting switched on automatically.

This menu will not harm the computer but constant OSD menu will most probably lead to permanent damage to the pixels in the LCD screen plus it is a constant irritation to your eyes which are most precious.

This problem can be rectified by replacing the faulty menu switch. Hope this solves your problem Thanks.

Osd main controls locked/unlocked pops up every 5 seconds


Press the Menu button ( marked OK) for one minute, or more, and a blue/red menu list should appear on screen.

Using the adjust button (immediately to the left of the OK button) by pressing the arrows at each end up or down as required you can enter the menu and select an action by scrolling.

At the end of the list of possible adjustments on the left of the screen (brightness, contrast, etc) is the Reset section.

On the righthand side of the screen is a flashing Yes No choice which automatically alternates.

The trick is to select the Reset choice on the left and while selected press the OK button when the Yes alternative on the right of the screen is flashing.

You VDU should then Reset and all will be well.

Screen ajustment

Hi stefan,

You can adjust manually using the OSD (on-screen display) menu of you monitor by pressing menu button. Other monitor OSDs cannot be accessed on single button but some combination of buttons but considering it can be accessed, please look for it. Try also changing the properties at Operating System GUID (graphics user interface display) Control Panel Display or your monitors display monitor application software. Try changing the frequencies and other special features like single screen or wide screen, etc..

Best regards,
