The 3M 28" Widescreen Monitor Privacy Filter is a solid fit for people who want their private data to stay out of sight. It shares the same patented microlouver technology used in 3M Framed Privacy Filters for LCDs and CRTs to block the view of curious onlookers who may try to view your screen from odd angles. At the same time, it does not diminish your own direct view of the screen. This allows you both ease of viewing and peace of mind when you need to access private information in open work environments or high-traffic areas. The easy-on, easy-off 3M privacy filter offers you a convenient way to protect your fragile LCD screen from scuffs and scratches. The screen filter is also reversible, giving you twice the amount of use out of it. The 3M wide screen privacy filter provides 1.5 times more effective privacy than the other competing models of screen filters.
