For use with widescreen notebooks, this screen privacy filter features reliable Micro Louvre technology, which creates an appearance of a black screen to anyone not directly in front of it. Ideal for those working with confidential or sensitive information, the screen filter also works to reduce glare and protects the delicate surface of the screen. The convenient design means there is no need to remove the screen filter when closing a laptop or notebook. This 14.1 inch widescreen filter comes with a soft, microfibre cleaning cloth.
