Changing the screen orientation of your Windows display can make your screen rotate at a 90-degree, 180-degree and 270-degree angle. By default, Windows operating systems do not come with a built-in mechanism to change the screen's orientation. Certain graphics boards, such as Intel, utilize hot keys to change the screen orientation. If the hot keys do not work on your computer, a program can be installed to create shortcuts that change the screen's orientation. One such program that is Windows compatible is called "iRotate," which is available to download for free.
Turn your computer on and wait for it to load. Once your computer finishes loading, make sure any open programs are minimized or closed. Press and hold the "Ctrl" and "Alt" keys on your keyboard. Press the corresponding arrow key on your keyboard for the direction to which you want to orient your screen. Press and hold the "Ctrl," "Alt" and up directional arrow key to return the screen to its regular orientation. iRotate Application Open the iRotate download site (see Bottom of page.) in your web browser.
