Frameless display privacy filter Lenovo 4Z11K07880 68.6 cm 30° viewing angle

The Lenovo 4Z11K07880 frameless display privacy filter is designed for monitors up to 68.6 cm (27") and narrows the visible screen area to ±30°, so screen content remains legible only to the person directly in front of the display. The filter also reduces harmful rays by up to 30% to ease eye strain and help limit blue light exposure that can affect sleep patterns. One face has a matte, anti-glare finish while the reverse is glossy for a clearer view; the matte surface includes a special antimicrobial film to inhibit mildew and bacterial growth that can cause stains and odours.

Advantages

This frameless privacy filter provides a 30° viewing protection that reduces the risk of visual data breaches in shared or public environments. It decreases glare and fingerprints on the matte side while offering a clearer image from the glossy side. The filter lowers exposure to harmful rays by up to 30%, contributing to reduced eye fatigue and decreased blue-light exposure. The antimicrobial coating on the matte surface helps prevent microbial growth, maintaining a cleaner film over time.

How to use

Align the frameless privacy filter with your monitor screen and attach it according to the manufacturer’s mounting method (adhesive tabs or removable mounting system as provided). Ensure the filter is centered and fully covers the display area for correct privacy protection. Use the glossy side when you need maximum clarity for viewing and the matte side to reduce glare and fingerprints; keep the matte side facing outward to benefit from the antimicrobial coating. Clean the filter with a soft, lint-free cloth and a mild screen cleaner; avoid abrasive materials.

Usage recommendations

For effective privacy and eye comfort, install the filter so the primary user sits directly in front of the screen. Regularly clean the filter following the care instructions and avoid exposing it to sharp objects or excessive heat to preserve the antimicrobial coating and optical properties.
