I have a synmaster 710MP in each operatory and one monitor has its menu setting locked. I do I unlock my menu settings?

pressing the Menu button takes you directly to the OSD settings menu. You should then select the Unlock option to unlock and allow user access to all applicable settings

menu is typical the "enter" button

The following site has step by step instructions on steps you can try: http://www.ehow.com/how_5008634_fix-lockout-display-computer-monitor.html
I'll paste them below: All computer monitors, whether they are LCD or CRT style, have a built-in feature called the on screen display (OSD) lock out that prevents users from viewing any images on the monitor. If your computer screen has accidentally been set to the OSD lock out setting, there are several different ways you can remove the lock out, depending on the make and model of your particular computer monitor.
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 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 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 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 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 over to the "Exit" setting and then hit the Menu key a final time to exit the menu setting and remove the OSD lock out.

The OSD can be enabled or disabled by pressing and holding the Menu button on the front panel for 10 seconds. If the OSD is locked, the warning message OSD Lock displays for ten seconds.

* If the OSD is locked, press and hold the Menu button for 10 seconds to unlock the OSD.
* If the OSD is unlocked, press and hold the Menu button for 10 seconds to lock the OSD.



OSD stands for "On Screen Display." It is an onscreen configuration menu included with various monitors. When you press the MENU button or one of the other buttons on the front or side of a monitor, the onscreen display may appear. The OSD typically includes monitor calibration options, such as brightness, contrast, and color adjustments. Some OSDs may also include horizontal and vertical position controls as well as tilt and keystone adjustments.
If you can't make adjustments to the monitor settings using the OSD interface, the onscreen display may be locked. You may also see the phrase "OSD Locked" appear when you try to change the settings. Some monitors include an option within the menu called "OSD Lock", which you can turn on or off. If this option is available, simply turn OSD Lock off and you will be able to make adjustments to the settings.
If your monitor does not include the "OSD Lock" option, you may be able to unlock the OSD by pressing and holding the MENU button on the front or side of the monitor for several seconds. If you try this method, be patient! It may take up to 15 seconds for the OSD to unlock.

Turn off monitor, hold down the menu button, turn the monitor back on, release the menu button after 10-20 seconds. Your Iiyama screen will now be unlocked.

On the monitor there is a menu button. Press and hold down on the Menu Button for approx. 10 seconds until you see the menu. This unlocks it. If you care to lock it again, just do the same thing. For the record, I have a HPw2207 monitor. Hope this helps. Jim

You could get a universal remote that will let you operate multiple devices all from the same remote. You would probably need to check it to see if it would control the monitor, but you might be able to treat it as a TV.

This is from the user manual for the monitor. You can download a copy from hp here:

There are four adjustable options on the OSD settings screen: Lock OSD settings, Timeout, H Position, and V Position.
To change OSD settings:
1 Open the OSD setting screen under the Advanced menu. See
“Using the On Screen Display” on page 25.
2 Press the Browse buttons to select the option you want to adjust.
3 Press the Select button to check the option.
To change OSD lock setting:
1 Press the Browse button to select yes (lock) or no (unlock). The
setting is automatically saved when you change the value.
2 Choose Exit sub-menu and press the Select button to return to
the OSD Main Menu or press the Menu button to exit OSD.
NOTE: Once OSD is locked, all OSD functions including the
shortcut buttons are disabled. If OSD is locked, pressing
any button on the monitor directly opens the Lock OSD
settings window so that you can unlock OSD.

Very easy fix, The problem is you have the TEXT close caption ON. Just go into the TV menu and turn the close caption OFF.
