3M Privacy Filter for 20" Widescreen Monitor (PF200W9B) Black, Matte, Glossy (MMMPF200W9B)

Privacy filter keeps confidential information private. Only persons directly in front of the monitor can see the image on screen while others on either side of it see a darkened screen. It is great for high-traffic areas and open office environments. Filter is designed to fit standard desktop LCD monitors with a diagonally measured, 20" viewing screen and a 16:9 aspect ratio. Actual filter dimensions are 17-7/16" wide x 9-13/16" high (443mm x 250mm). Filter includes your choice of two easy attachment methods. Reversible, matte side reduces glare and reflections. Lightweight, thin, frameless design protects display from dirt, debris and scratches. Clean easily with a soft cloth and water.
