The Brightness/Contrast Box pops up on the screen by its self. I have tried two separate computors and the problem is still there. The blue bar fluxuates between Exit, Brightness and Contrast. It will go away on its own for short periods of time, but comes back.

Re: Dell E173FP 17-inch Flat Panel Color LCD Monitor
The dell monitors are bad with capacitors going out, check caps in power supply and video board.
You can use a can of freeze, it would be easier that way. Just be careful not to touch anything, because these monitors can shock easy.

To help you change the brightness and contrast settings from the LCD monitor, please follow the instructions mentioned below,
The control buttons are located at front panel of the monitor. The Brightness Button is used to select the Brightness/Contrast adjust functions. Press to switch functions or adjust settings.
To decrease the brightness or contrast press (-) button & to increase (+) as per your adjustment.
Try pushing the buttons for the brightness if it does the same thing you need to replace it, the buttons might be damaged already by pushing too hard or it got stuck. If this is just a new LCD monitor about 1 to 2 years old contact tech support of dell so you can get this replaced.
In case the above does not work, do this: - Do a factory reset on All Settings. http://support.dell.com/support/edocs/monitors/E173FP/En/controls.htm
If the above does not resolve the problem, change the video settings on the Operating system or on the graphics configuration settings. If your system is running on Windows, boot it to safe mode first.
the micro switches on the monitor are getting short which is triggering the menu, try to clean it with a switch cleaner or check if the switches can be replaced, do this only if u r an expert in handling things like this or take some proffessional assistance.
I have the same problem. It seems like a virus to me, but my anti-virus doesn't find anything. I went to the main menu on the moniter and changed the display time to five seconds and locked the OSD display. Now all the appears is a smaller box showing a lock which goes out in five seconds. It is still annoying, but less intrusive then before. Hopefully, some one will determine a permanent fix for this problem.
