If your refering to a secondary monitor this can be done ONLY if you have a video card that supports dual monitor. If you do, set them up for dual monitor mode if its nvidia, ati will have something similar as well. Then you can just drag and drop the icons. If your video card does not support dual monitor, then there is not a way of doing it that I know of.
