Open Magnifier by clicking the Start button , clicking All Programs, clicking Accessories, clicking Ease of Access, and then clicking Magnifier.
Change any of the following Magnifier settings:
To invert the colors for better readability, select Invert Colors. This might be useful if, for example, a document has black text on a white background but for you, white text on a black background is easier to read.
To dock the Magnifier window to the edge of the screen, select Docked, and then click a location from the Dock Position list.
To keep the Magnifier settings dialog box minimized when you open Magnifier, select Minimize on Startup.
