"This is the solution I ended up using. It's probably specific to my graphics card, but it's probably at least similar to other cards' methods.
-Go to the regular display settings window (open a context menu from the desktop and select Properties) -Go to the settings tab and click on the monitor to rotate -Click Advanced -Select the graphics card's tab -- in my case, the Quadro tab -- and choose the rotation menu item -- in my case, ""NVRotate"" from the popout menu -Select the radio button for the desired orientation and click Apply"
"The free product iRotate handles multiple monitors:
iRotate provides convenient access to the native rotation capabilities present in contemporary display drivers, via a popup menu accessible from the system tray and optional system-wide hotkeys. It's no longer necessary to resort to bloated Windows hacks, additional software layers or phantom drivers to achieve content rotation. In most instances, support is now available directly from the graphics chip manufacturers, who continuously improve and apply quality assurance to their drivers.
By leveraging the native rotation capabilities now provided by ATI, nVidia, Intel, Matrox, S3, XGI and others, iRotate offers exceptional speed and efficiency, with minimal impact on scarce system resources - the entire iRotate package, including installation, documentation, and native language support in all the major European and Asian languages, weighs in at only 125kb. And like all EnTech graphics utilities, iRotate supports multiple graphics cards from various vendors, simultaneously, under every multi-monitor enabled operating system from Windows 98 to Vista."

I couldn’t get the Cntrl+Alt +Arrow to work on my Windows 7 machine."
This stuff's in your drivers, assuming you run windows, so simply install them. You may have to go through the card's control thingy (As in, Catalyst for ATI, or the nVidia control panel) instead of the windows dialogue, I did.
Follow thilina's advice until you get to the monitor page. Click "Graphics Properties", the button with the Intel blue chip on the left side. Go to the rotation area. Make sure you are on your 2nd monitor on the dropdown menu. Rotate it. Boom. Done.
