Screen upside down - Dell Latitude E5420 Laptop Computer

Rotating the screen image is a feature of the graphics card and is normally caused by accidentally pressing a combination of keys. To correct it, hold down Ctrl and Alt and press one of the four arrow keys (up, down, left or right) until you have it the correct way up.

As your screen is completely upside down, hold down Ctrl and Alt and press the Up arrow key.

Alternatively, you probably have a Rotation setting in the display properties of the graphics card. You should be able to reach your graphic card settings, but reading and setting them properly may be difficult since everything you see on the screen is upside down until it's fixed.

If all else fails, try restoring the system to an earlier date when the display was right. This will reset the driver to its proper orientation.

Do the picture to broadcasts appear correctly? Provide more details please.

Hi.

You may have accidentally hit a sequence of keys and now your Windows screen is upside down.

Press Ctrl + Alt + arrow (left, right, up or down) to rotate the screen to the correct way.

I have a Sony Ericsson c905 phone and the screen is perfect, but upside down on all applications. Otherwise the phone operates normally. How can I fix this?

Windows XP: Flipping the screen upside down and back again


Once, at University, someone had flipped the screens of all the public computers (running on Windows XP) of the English Department upside down. The wallpaper, desktop icons, fonts, mouse-cursor and even the start-up screen...everything was displayed or moved upside down. People could not check out their e-mails or surf or do anything.
To reverse the upside down screen mode, press ctrl, alt and the up arrow (arrows console) at the same time; the screen will probably go blank. Turn off the monitor, turn it on again and the display will be normal again. If you possess a sense of humour or are antisocial, press ctrl, alt and the down arrow simultaneously, turn off the monitor, turn it on again and everyone (excluding the culprit) will be desperate --> upside down! Works for Windows XP Home and Prof.

Hold down CTRL-ALT- UP arrow key
