Kensington MagPro for 27" Monitor (16:9), two-way, magnetic, removable

"The Kensington MagPro™ magnetic privacy filter for a 27"" 16:9 monitor protects your private data on your device's screen. It also protects the display from damage and scratches. The filter is easily and quickly attached to the magnetic strips included in the package. An important feature of the filter is the reduction of the viewing angle to +/- 30 degrees. A person observing your monitor from the side will see only a dark screen. The double-sided design of the filter gives you the option to choose between a matte and a glossy surface finish. The privacy filter also reduces harmful blue light by up to 22% and reduces glare thanks to a low-reflection surface finish (when the matte side of the filter is selected).

• The removable Kensington magnetic privacy filter helps protect sensitive data on the screen of your 27"" monitor.
• The privacy filter can be easily and effortlessly attached or removed from the magnetic strips as needed. The privacy filter is therefore not permanently glued to the monitor display.
• It limits the display's viewing angle to +/- 30° from 2 directions (left and right side) and thus helps protect sensitive information from all observers who would try to look at the device screen from the side.
• It reduces harmful blue light emitted from the monitor display by up to 22%. This helps relieve eye strain and supports your natural sleep cycle.
• The low-reflection surface finish reduces glare on the display and improves readability. The display surface will be matte after the filter is applied (when the matte side of the filter is selected).
• Protects the screen from scratches, damage and fingerprints.
• Ideal solution for monitors with thin or borderless displays.
• Double-sided matte/glossy design.
• A cleaning cloth is included in the package.
• Dimensions of the magnetic privacy filter: 598x432x0.9 mm (W x H x D)."
