Features: Privacy Screen Filter Size: If the visible area of your display has the following dimension: Width x Height (Exclude Frame/Arrow 1 to 3 mm errors): 20 15/16" x 11 13/16" (532 mm x 299 mm), then this filter is good for you. Very Important to double check your screen's Width and Height excluding frame before ordering. It's not recommended to make your selection based solely on your screen's diagonal size Left and Right Privacy: Not block visibility directly behind you, regardless of distance. The privacy filter makes the screen appear dark when looking at it from an angle (left and right 30 to 180 degree), but clear when looking directly at it. To change the privacy levels, simply adjust your monitor's brightness level accordingly Matte and Glossy Sides: It's a reversible privacy screen filter, giving you the flexibility to choose glossy or matte finish. The matte side will have less glare, however the glossy side will have stronger privacy Perfect for Open Workspaces: Ensure your working space is bright and well lit. Privacy screens do not work in dimly lit areas Two Installation Option: Option 1 uses clear double side adhesive strips that securely attach to any computer screen. Option 2 (for computer screens with a raised bezel only) uses slide mount tabs that easily stick to the display frame, allowing you to take out the privacy screen filter easily as needed Package Includes: 1 x Office privacy screen Listing and template services provided by inkFrog
