Origin Storage Security Filter 4-way plug-in HP E233 Monitor (23in) 16:9

A Security Filter from Origin Storage helps provide protection against shoulder surfers and visual hackers viewing your confidential and sensitive information on your computer screen. With a Security Filter from Origin the intended users view of the screen remains crystal clear whilst people viewing the screen from the sides see only a dark screen, almost as if the screen is turned off, preventing them seeing your information. Designed to be easy to fit the Origin Storage Security Filter is quick and simple to attach to your screen. Once fitted it can be removed and reattached just as easily for those times when you need to share your screen with other people.
