Okay, my computer screen has just gone upside down for no apparent reason. I’ve turned my laptop off and restarted, and while the initial Dell logo is right side up, as soon as Windows comes up I’m upside down again.
Whaddaya think - virus? Odd software glitch that will sort itself out?Avast has not found anthing nasty but that doesn’t mean it isn’t there.
Apologies for any typos - it is remarkably hard to type like this.
Try hitting CTRL + ALT + Up arrow. Some notebooks allow you to change the orientation of the screen. Up arrow for top-up, right arrow for right-up, left arrow for left-up, and down arrow for bottom-up (upside down). Don’t know why it would change spontaneously upon restart, though.
Winner(s)! Yep, I must have leaned on the wrong combination of buttons at some point. I had no idea that you could do that, nor indeed why you would want to.
The world is the right way around again, and any typos are now down to the usual fumblefingeredness. Thanks very much indeed.
This has just given me an idea. When processing portrait-orientation photographs, I could tip the lappy on its side and use an external keyboard and mouse.
Glad you got an answer. I had this happen at work once, and had no flipping idea what happened. I Googled the answer, but it was a head-turning experience.
The first thing I do when I get a new graphics card and install the drivers is go into the control panel (i.e. Catalyst Control Center for ATI cards) and find the option that says “disable screen rotation” and check it. It was a common prank to pull in my high school computer lab so I do it just to be safe.
That’s one way to use it. I also do it for reading eBooks sometimes; I’ll flip the screen sideways and hold the laptop like a book. Silly, maybe, but that’s how I roll.
It’s a feature with a number of uses - some monitors swivel through 90 degrees to provide a portrait-aspect display. Some displays tip over backwards so that (for example) a receptionist can show a map to a visitor. Some laptops open out flat so rotating the display means you can present something on screen across a table, etc.
An earlier version of this gag required a bit more tech savvy. Loosening the clamp on the deflection yoke of a crt based monitor or TV allowed it to be rotated 180° resulting in an upside down picture.
A more subtle trick was to reverse the polarity of the horizontal sweep signal causing a mirror flip.
