display designs

How can I make my monitor display vertically, as it was designed to do?
I have just successfully integrated a Dell 2007WFP monitor with my HP Pavilion dv5000 laptop, but cannot get the monitor to display vertically.
I have looked at drivers from both Dell and HP without success, and am therefore lost as what to do.
Try right-clicking on your desktop and check if there’s any option to access your video card’s options. It will probably be ATI or nVidia. Use the options there to rotate the display.
