Targus Privacy Screen 12.1"W is an anti-glare privacy screen for LCDs & notebooks. It is easy to attach and remove, and it can be used in both portrait and landscape orientations. The screen is designed to protect your privacy by limiting the viewing angle to +/- 30 degrees, making it difficult for people to see your screen from the side. It is also reversible, with a glossy side and a matte side, so you can choose the finish that best suits your needs.
