Targus 4Vu Frameless Display Privacy Filter 31.2 Cm (12.3")

Whether you’ve got a co-worker that’s too close for comfort, a workstation located in a busy area, or often work in public places like cafes or airports, you’re probably concerned about visual privacy and guarding the information on the screen of your Surface™ Pro. There’s a simple yet effective solution: the Targus 4Vu™ Privacy Filter.
Designed to attach to your Surface Pro’s display and shield your data from casual viewers, the 4Vu Privacy Filter offers an opaque view of your screen to anyone not directly in front of your display or closer than 30 degrees to either side. So you can view, read, or type with confidence, even in a crowded room.
