How to Unlock OSD on a ViewSonic Monitor
By Kirk Bennet
If you use ViewSonic monitors in your small business and don't want your employees and clients to change their settings, you can lock their OSD -- On-Screen Display -- to lock all settings. However, if you no longer have the manual for the monitor and want to change the settings, you must find a way to unlock it. Unlocking the OSD of your business monitors is a straightforward process that takes just a few minutes.
ViewSonic LCD and CRT Monitors
Turn on the ViewSonic monitor.
Press the button labeled "1" and the "Up" button simultaneously for at least 10 seconds if you have an LCD monitor.
Hold the button labeled "1" and the "Down" button for at least five seconds, if you have a CRT monitor.
The buttons are usually located on the front of the monitor. You will see the "OSD Unlocked" message on your monitor when it's unlocked.
