Blue lock pops up. can not use menu buttons. screen is too bright.


The lock that pops up is called OSD Lock, with this there are no adjustment can be made by a user and only menu button will work. For you to disable it, just press the menu button for about 15 - 20 secs.

Lock on monitor adjustments don't know how to turn off the lock so we can adjust brightness and color

Follow these instructions :
  1. Turn on your Samsung monitor (if it isn't already.)

  2. Press the "AUTO" button on your Samsung monitor. This will run the automatic configuration utility. This will look at your current computer settings and adjust your monitor to best match those. This will take a few seconds. If this has calibrated the monitor to meet your needs, you are finished with the process. If it hasn't, continue to Step 3.
  3. Press the "Menu" button on your Samsung computer monitor.
  4. Use the arrows and the "Enter" button on the monitor to highlight and select various settings categories.
  5. Use the "Brightness" menu on your Samsung monitor to adjust how bright or dark you want the image.
  6. Use the "Colors" menu to adjust how prominent certain colors are displayed on your Samsung monitor.
  7. Use the "Contrast" menu to adjust the level of black on your Samsung monitor.
  8. Select "Save and Exit" to save your changes and exit the Samsung monitor's on Screen menu.

Brightness/contrast window pops up and scrolls through fast

The up/down button on your flat panel is stuck. Please contact Dell Technical Support to have the monitor replaced if its still within warranty.

Want to unlock my monitor

This is the function that locks the OSD in order to keep the current states of
settings or prevent others from adjusting the current settings.

1. Lock : Hold down the menu button for more than five seconds to activate
the OSD adjustment lock function.

2. Unlock : Hold down the menu button for more than five seconds to
deactivate the OSD adjustment lock function.

Though the OSD adjustment lock function is activated, you can still
adjust the brightness and contrast, and adjust MagicBright ( )
using the Direct button.
