Privacy Screen Filter for 25 Inch Desktop Widescreen Monitor — 21.81 inch x 12.28 inch

Actual privacy filter size is 25 inch measured diagonally. Filter dimensions: 21.81 inch width x 12.28 inch high — please compare these measurements with your screen before purchasing. The filter prevents side viewing at angles greater than 30 degrees from center, but does NOT block visibility from behind you. Built with anti-scratch and anti-peeping properties, it also reduces reflections from ambient and overhead lighting. Installation is simple and flexible: either slide the screen on and off or install it as a permanent mount — two installation options for easy setup.
