Rocstor Microsoft® Surface® Pro 12.3" filter with 13:2 aspect ratio privacy screen delivers the most advanced Microlouver Privacy Technology. Rocstor privacy filters features a new Easy-On technology, hassle free, allowing quick and easy application and removal every time. Rocstor privacy filters with Easy-On technology strips are washable to remove any dirt or debris. The PrivacyView™ filters also protect from visual hackers and at the same time provides an amazing clear image for your direct view. Rocstor's advanced Privacy technology protects your information with tiny vertical blinds that are built on the surface of the filter which narrows the viewing angle. The information on your display would be only visible directly in front of the display up to 30 degrees away from the center of the screen and the sides are blacked out from outside of 60-degree viewing angle. Rocstor filters reduce display blue light by 35%. Use Rocstor's PrivacyView™ screen filters to support compliance with privacy regulations such as Health Insurance Portability Accountability ACT (HIPAA) and Health Information Technology for Economics and Clinical Health (HITECH). Rocstor's privacy screen filters are the means for protecting private and personal corporate, legal and medical records. Use your PrivacyView™ filters with confidence backed by exceptional Rocstor's Two-year limited warranty.
