Since the green laser pointer display is transmitted directly with the image, it is independent of the presentation technology. While the light point of a high power laser pointer is not displayed on an LCD display, the MagicPresenter can also be used to transfer it to LCD, LED and PDP panels. By doing without laser technology, the MagicPresenter is also harmless to the human eye.
