Before you rotate the monitor, your monitor should
either be vertically extended (Vertical
Extension) or titled (Tilt)
to avoid hitting the bottom edge of the monitor.
After you have rotated your monitor, you need to complete the procedure below
to rotate your operating system.
NOTE:
If you are using the
monitor with a non-Dell computer, you need to go the graphics driver
website or your computer manufacturer website for information on rotating
your operating system.
Right-click on the desktop and click Properties.
Select the Settings tab and click Advanced.
If you have ATI, select the Rotation tab and set the preferred
rotation.
If you have nVidia, click the nVidia tab, in the left-hand
column select NVRotate, and then select the preferred rotation.
If you have Intel, select the Intel graphics tab, click Graphic
Properties, select the Rotation tab, and then set the preferred
rotation.
NOTE:
If you do not see the
rotation option or it is not working correctly, go to support.dell.com and
download the latest driver for your graphics card.
