IRotate is an easy-to-use screen rotation tool, that will rotate your screen through 90, 180 or 270 degrees.
If your monitor will rotate then this could be very useful. Spin it into a portrait, rather than landscape orientation and you'll have a much more natural view for working on lengthy document pages, web pages and more.
Once iRotate is installed, you can then rotate your Windows display to match, either through a hotkey (Ctrl+Alt+Left will rotate your monitor picture by 90 degrees), or right-clicking the iRotate system tray icon and choosing the appropriate option.
The program should work with just about any modern display drivers. And while the authors officially support running in on Windows 98 to Vista, we found it worked on Windows 7, too. Still, if there is a problem then you may have to reboot to restore normal operations, so make sure you save any open documents before running iRotate for the first time.
Please note, iRotate is free for personal use only. Business use requires that you purchase a licence, but prices are low, starting at under $1 per user for a 50-user licence. See the Buy link for more.
