23.6 inch Computer Privacy Screen (16:9) - Black Security Shield

In this review of the 23.6 inch Computer Privacy Screen by Akamai Office Products, the bottom line is straightforward: it is for anyone who uses a desktop monitor in semi-public spaces and needs reliable side-view privacy without replacing their display. The reviewer found the filter delivers the primary promise of keeping visual hackers in the dark while preserving clear forward visibility, and it also adds useful blue light reduction and physical screen protection. Installation is simple, and compatibility with common brands makes it a practical privacy upgrade for office and home setups.

Key Features

• Exact fit dimensions: The filter is sized to length 20 9/16 in and height 11 9/16 in so it matches a 23.6 in diagonal 16:9 monitor when width and height are verified before ordering.
• Side-view blackout privacy: The Blackout Privacy Screen darkens the LCD when seen from the sides, which prevents onlookers from reading sensitive content while keeping your forward view clear.
• Blue light reduction: The filter cuts approximately 70% of harmful blue light to reduce eye strain during long sessions in front of a monitor.
• Durable surface: With a 9H hardness rating the polymer film adds a layer of physical protection against scratches and everyday wear.
• Broad compatibility: Engineered to work with HP, Dell, Samsung, Lenovo, LG, Acer, ASUS, ViewSonic and other brands when you match the width and height.
• Simple installation: Uses high quality 3M adhesives and includes full instructions so applying the privacy cover is straightforward for most users.

Who It's For

The screen is best for professionals, remote workers, and anyone who regularly views confidential documents on a desktop monitor in co-working spaces, offices, or public areas. Its combination of side-view privacy and blue light reduction makes it suitable for intensive daytime use and for users concerned about shoulder-surfing.

It is less appropriate for people who base purchases solely on diagonal size without checking actual display width and height, or for users who expect heavy anti-glare performance beyond what customers described as mixed results; those needing maximum glare elimination should consider a dedicated anti-glare hood or different coating.

Pros & Cons
