Whats the reason for ghost images?
If you look at a 3D image through the 3D glasses you may see ghost images. That means parts of the image which should be only visible with one eye is also visible with the other eye. This will happen when the colors that are displayed on the screen do not completely match the colors which can pass the red and green filters of the 3D glasses. Sometimes this is caused by the monitor itself which doesn’t show neutral colors (especially displays of older Notebook computers do not have a good color quality, but also the current iBooks and PowerBooks do not have really good displays). Also the monitor must be set to thousands or millions of colors.
