How do I make my screen portrait?

[Jimmy]

So I have a gig on friday, and instead of taking five or six books about as fat as half a phone book each, I have a scanned in son my laptop. What I I want to do is just take my laptop and read off that, but the whole page of music doesn't fit on the screen while it is on landscape.

I have a widescreen and (apparently) I have a Nvidea (or how ever you spell it) graphics card. All I want to do is make the screen go sideways so i can view a full page of music.

Hmm, I think there's a virus on some of the computers at our school which when you open them do that to your screen. Seriously.

Now about helping you, I'm not sure on how to do that, but if you can't ordinarily switch something so that the screen does that, which I don't think you can, you might be able to find a program that isn't a virus which can do it for you. If you Google for it. Also, you know the settings for monitors that you can change when you press the buttons on your monitor, e.g. brightness, I think that on some computers there's a setting for rotation. Although that may only be able to rotate in the range -30 degrees to +30 degrees. Or not 90 degrees anyway.

A quick Google throws up this (http://www.nvidia.com/object/feature_nvrotate.html). I'd imagine it has a control panel setting or keyboard shortcut which lets you rotate the screen without one of those pivoty monitors

edit - Hmm, I think there's a virus on some of the computers at our school which when you open them do that to your screen. Seriously.
On some Dells (I think it's ones with Intel graphics cards) there's a shortcut to rotate the screen - ctrl+alt+[any arrow key]. The 'virus' might just be simulating those keypresses

edit again - Glooomp, if it's scanned in why not just rotate the image?

That's all good, but it doesn't tell me how to do it...

Apparently because I have NVidea I should have a program like that or something but I can't even find the video card controller on my computer. I'll keep searching. Thanks :)

edit: I found a program called iRotate (http://www.softpedia.com/progDownload/iRotate-Download-17093.html) which works fine.
