3m Notebook Privacy Filter Fits 15.4 In. Widescreen

3M's microlouver privacy filter limits the viewing angle of your laptop's LCD. While you'll be able to see the screen just fine from directly in front of it the LCD will appear dark when viewed from the side. The filter can be easily removed as it slides into self-adhesive guides you apply to your screen. Laptop not included. To determine needed filter size use the diagonal measurement of your LCD's viewable area.
