3M frameless display privacy filter BP121W1B for 30.7 cm (12.1 inch) laptops, 16:10, anti-glare, black

The 3M frameless display privacy filter BP121W1B is designed for laptops with a 30.7 cm (12.1") display and a 16:10 aspect ratio. This thin, frameless filter reduces side visibility to protect on-screen information while preserving most of the display’s brightness. Its anti-glare surface reduces reflections and a scratch-resistant coating helps maintain a clean viewing area during everyday mobile use. The product colour is black and it is intended for laptop displays where privacy and reduced glare are priorities.

Advantages

The frameless construction provides a discreet, low-profile fit that does not obscure the edges of the display. The filter limits the viewing angle to about 60° to prevent side viewing while retaining approximately 85% light transmission for clear visibility from straight ahead. An anti-glare finish reduces reflections under ambient light and the scratch-resistant surface improves durability during frequent handling and cleaning.

• Laptops with a 12.1" (30.7 cm) screen and 16:10 aspect ratio
• Mobile professionals working in open-plan offices or on public transport

How to use

Clean the laptop screen following the manufacturer’s guidelines and ensure it is fully dry. Align the frameless filter with the display edges and attach according to the included mounting method (adhesive strips or removable tabs as supplied). Position the filter so it sits flat against the screen, then check that the image is clear when viewed head-on and obscured from side angles. Remove the filter by peeling it off gently if repositioning or cleaning is required.

Recommendations

For optimal performance, clean the filter surface with a soft, lint-free cloth and a mild screen cleaner; avoid abrasive materials or strong solvents. Reapply following the included instructions if the filter becomes misaligned. Use the filter in combination with standard device security practices (passwords, screen locks) for comprehensive protection of on-screen information.
