The monitor privacy screen cover is easy to attach and remove. Simply attach the 19 inch privacy screen to your 16:10 aspect ratio display using the attachment strips or slide-mount tabs. This confidentiality screen filter is also reversible. The matte side provides you with glare reduction and the glossy side of the widescreen computer privacy film provides increased clarity. Protect Your Privacy The privacy screen protector for desktop monitors is a great investment when it comes to protecting your data. It is a convenient and cost-effective way to keep your classified information, intellectual property or any other important data you wish to keep protected. You can have a peace of mind while working in the office or public environments because you know your screen is protected with the 30+/- degree privacy viewing angle. The cutout on the top corner of the privacy screen makes it easy to remove for sharing content with trusted audiences or switching between finishes. Blue Light Reduction Lowering blue light exposure is important. To reduce digital eye strain, the monitor privacy film blocks between 40% to 51% of the blue light in the wavelength range of 380nm to 480nm. Display Care Add a durable layer of protection from dust, scratches, and fingerprints on your screen from everyday use. Use the included wiping cloth to clean the privacy screen on a regular basis.
