A while ago, my cutie li'l niece suddenly pressed some buttons on the keyboard of her dad's MacBook... We don't know how did she do it that the display on the screen is on Vertical position already... Kept on pressing different buttons but still can't fix it... Her dad left it on his flat and let me use it coz they were about to go. And so I tried to restart but to no avail it didn't work... I've tried searching on the control pannel but couldn't find the right solution.
I think you'd suffer from a stiff neck if you keep on reading and using the book and the screen's on vertical position, lol. So, I've asked some of my friends if they have any idea on how to fix it... A good friend of mine, Ghenessa, suggested something but still it didn't work out... I've tried searching on the internet but can't stay long reading it with my neck on the right side always...
This is how it looked like...

It was a good thing that one of my best friend Jane, was online and she did helped me out on my problem... and we did finally fix it (Actually siya ang naka-discover hehehe).
So, What did we do???
Press CTRL + ALT + UP ARROW... As simple as that... My niece is really makulit kasi, well atleast We've learned something from what happened and now I can see my monitor displays normally... =)
