I have HP 1740 model monitor ,and I have problem because in the middle of the monitor appear OSD Lockout and I can not remove it/

This document pertains to LCD monitors .
One of the following messages appears on the screen (over the items being displayed).
OSD Lockout
OSD Lock-out
... or similar message.
This message occurs when the Menu button on the front panel is pressed for more than 10 seconds. OSD lockout prevents the OSD menu from opening on the screen when a button is accidentally pressed.
NOTE: The button may be different and the procedure might vary on some monitors. Please check your monitor User Guide to find the exact procedure if this procedure does not work.
To remove the OSD Lockout message, release the Menu button (if something was pressing against it), and press and hold the Menu button again for about 10 seconds - until the message goes away. If the OSD Lockout message does not go away, the button may be stuck or the hardware behind the button might have become defective.

All computer monitors, whether they are LCD or CRT style, have a built-in feature called the on-screen display (OSD) lockout that prevents users from viewing any images on the monitor. If your computer screen has accidentally been set to the OSD lockout setting, there are several ways you can remove the lockout.

Power off your computer and then remove the monitor cable from the port on the back side of the computer case. Reattach the cable and make sure the pins are correctly screwed in. Power the computer back on and check to see if the OSD lockout message is still being displayed. Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lockout message. Find the OSD lockout heading and read the method that your particular model uses to remove the lockout. Attempt generic lockout removal procedures if you no longer have the manual that came with your monitor. Press and hold the "Menu" button located at the bottom of your monitor for 15 seconds and wait to see if the OSD lockout message disappears. Press the "Menu" button again if the lockout message remains on the screen. Use the arrow buttons to navigate through the main menu options. Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings. Scroll down to the "OSD Lock" heading. Use the arrow keys to change the setting to "No." Hit the Menu key again to return to the main menu. Scroll to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lockout.

Sounds like possibly the panel with all the buttons is dieing.

1. Power your computer completely off and then remove the monitor cable from the port on the back side of the computer case. Reattach the cable and make sure the pins are correctly screwed in all of the way. Power the computer back on and check to see if the OSD lock out message is still being displayed.
   
2. Step 2 Check the manual that came with your computer or monitor and locate the troubleshooting section if you are still receiving the OSD lock out message. Find the OSD lock out heading and read the method that your particular model of monitor uses to remove the lock out. Follow the instructions to remove the lock out.
   
3. Step 3 Attempt generic lock out removal procedures if you no longer have the manual that came with your monitor. Press and hold the "Menu" button located at the bottom end of your monitor for 15 seconds and wait to see if the OSD lock out message disappears.
   
4. Step 4 Press the "Menu" button again if the lock out message remains on the screen. Use the arrow buttons to navigate through the main menu options. Highlight the "Settings" or "OSD Menu" option and then hit the Menu key again to access the new list of settings.
   
5. Step 5 jQuery(document).ready(function(){ jQuery('#jsArticleStep5 span.image a:first').attr('href','http://i.ehow.com/images/a04/or/7q/fix-lockout-display-computer-monitor-1.5-800X800.jpg'); }); The OSD Settings Menu Scroll down to the "OSD Lock" heading.

Hi,

OSD (On Screen Display) lockout. To resolve the issue you can hold the power button of the monitor until you get another message something similar to "OSD unlocked"

try holding menu button also if it doesnt workout

OSD Lockout in HP Monitors First restart the Computer. Then hold down the menu button for 30 seconds, the main menu appears, then exist the main menu, then remove power cable of the monitor, then hold down the power on button of the Monitor for 30 seconds, then plug the power cable to the monitor.
