To unlock the OSD (onscreen display control), turn off the monitor and then press and hold the Menu button on the monitor. Then press the power button to turn the monitor back on. Do not release the Menu button before pressing the power button. This same step (holding the Menu button and then pressing the power button) enables the OSD lock. The menu button is the top button on the right side of the monitor (on the bezel). The power button is the bottom button of the group. AOC has the documentation for the 2036sa here: http://us.aoc.com/monitor_displays/2036sa . See page 20 of the User's Guide for the OSD lock procedure. The picture of the monitor buttons is on page 19. The guide is available as a PDF on the AOC site. Note: you will need Adobe Reader or a similar program to read the file.

I hope this helps.

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.

Things to check: Are your display settings set to "native resolution" of your screen. The native resolution is the actual dimensions (in pixels) of your flat-panel screen.
Looks like the Dell E153FP 15" has a native resolution of 1024x768. In windows, go to your control panel, in display settings, and ensure the resolution is set to 1024x768.
If that does not work, you can try the "auto adjust" feature on the monitor. On many Dell monitors, you can get this by pressing and holding the + button (on the monitor). You'll see the words "auto-adjust" appear on the screen if this works. If that doesn't work, you may be able to find auto adjust by navigating the menues in your monitor's menu, which you can get to by pressing the "menu" button on your monitor (sometimes this looks like a little rectangle icon). If it's an alignment problem, this should fix it right away.
If neither of the above work, it's probably your video card. Make sure your video card drivers are the correct ones for your card and OS, and up to date. You can also mess with display options under Control Panel > Display, under the "settings" tab, and at the bottom click the "Advanced" button, and it will bring up the advanced settings for your videocard.
Good luck!

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

usually this is controlled from a small separate board you can find them on ebay for about 20 dollars.
