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: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01632269&tmp_track_link=ot_recdoc/c01643091/en_us/c01632269/loc:1&lc=en&dlc=en&cc=us&product=3770762


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 Warning Messages A warning message may appear on the screen indicating that the monitor is out of sync range.
Cannot Display This Video Mode
This means that the monitor cannot synchronize with the signal that it is receiving from the computer. Either the signal is too high or too low for the monitor to use. See Specifications for the Horizontal and Vertical frequency ranges addressable by this monitor. Recommended mode is 1024x768 @ 60Hz.
Occasionally, no warning message appears, but the screen is blank. This could also indicate that the monitor is not synchronizing with the computer or the monitor is in a power save mode.

Try to change the desktop display settings, see screenshots below, see if it works

this is actually from dell support website.. hope it will correct your problem...


1 Ensure the correct resolution is set for the monitor. Flat panel monitors display the sharpest, clearest images when set to their optimal resolution. Sometimes games and other programs will change the resolution then fail to set it back once they are closed. This will then make the desktop look big, distorted, and grainy. Perform the following steps to adjust the resolution:

1. Right-click an empty area of the desktop, and then click Properties. (Or, click Start, click Control Panel, and then double-click Display.)
   
   
2. In the Display Properties window, click the Settings tab.
   
   
3. Under Screen resolution, move the slider to the desired setting. For most flat panels the optimal setting will be all the way to the right.
   
   
4. Click Apply, and then click OK.
   
   
5. If prompted, restart the computer.

NOTE: If the resolution will not adjust to the appropriate settings, the video driver may need to be reinstalled or updated.


2 Ensure the screen is clean. Finger prints and smudges will make the screen look blurry. Clean the screen with a soft lint free cloth. If needed, dampen the cloth with warm water or use a LCD cleaning kit that can be purchased from most electronics stores.
3 Use the On Screen Display (OSD) on the monitor to select the Auto Adjust feature. Selecting this will synch the video signal and can sharpen the video image.
4 Reseat the video signal cable to ensure a secure connection.
5 Use the On Screen Display (OSD) on the monitor to select the Factory Reset feature.
6 Test the monitor on another computer or test another monitor on this computer. If available, testing different hardware will isolate if the problem stays with the computer or monitor

Hi, maybe DVI cable or port is faulty, to test you could use VGA port , in the following picture you can see installation of monitor.
