You wake up in the morning, have a good long yawn, get out of bed, and check your email before going to work. You instinctively move your mouse down to the task bar only to find out that the mouse is moving up to an upside down task bar and your whole display turned over 180 degrees. Save yourself the neck pain of turning your head sideways. There’s a solution to this that’s much easier than bolting your desk to the ceiling.
There’s no easy way to find out the reason behind this. If you left your computer on overnight, however, it’s very possible that a pet or a small child might have fooled around with the computer. Perhaps even someone wanted to play a prank on you. What I’m trying to tell you is that you likely won’t have to experience this issue again if you know how to fix it.
This problem happens when the orientation of the screen is changed in Windows 7 to “Landscape (flipped)”. If you installed a new monitor and the desktop shows in its normal orientation on the old monitor, perhaps the new monitor just doesn’t read data sent from the computer the same way and you have to change the orientation. Windows doesn’t automatically detect a monitor’s 0,0 coordinate, so you might have to manually configure it in rare occasions. Depending on how quickly you adapt to the awkward mouse movements, this might take one minute or less of your time to resolve, even if you are not an expert at Windows.
There is one simple and elegant solution to this in Windows 7. Start by right-clicking on an empty space on your desktop and clicking “Screen Resolution”. Keep in mind that every move you make with your mouse will give you the opposite movement on the mouse pointer.
Once inside, click the drop-down menu next to “Orientation” and select “Landscape.” If you saw “Landscape” selected already, and your desktop is upside down, select “Landscape (flipped).” Click “OK” to save the changes.
When you leave your computer unattended, try as much as possible to put it to sleep or hibernate. This prevents any children or you may have in the house from scrambling around your settings. If someone pulled a prank on you, avoid telling the person that you resolved the issue. This might encourage the person to get a little more creative in his or her next prank.
Regarding monitor orientation, you cannot prevent the problem from happening again if the monitor has a different x,y zero coordinate than Windows expects. You can rest assured, though, that your computer won’t greet you like a possum the next time you restart it.
