The Peslv Magnetic Privacy Screen is a precision-cut analog filter designed for integration with MacBook Pro 16.2-inch chassis (A2485/A2780/A2991/A3186). Technical testing indicates that the unit utilizes the laptop's internal bezel magnets for alignment, eliminating the need for adhesives. The hardware is composed of a 0.4mm multi-layered Polyethylene Terephthalate (PET) substrate. Micro-louver technology is employed to block light transmission beyond a 30-degree arc from the center, effectively narrowing the visible field for peripheral observers.
Operational data reveals a 12-15% reduction in overall screen luminance, necessitating an increase in nit output for standardized visibility. Material analysis identifies a specialized coating for blue light filtration. Physical constraints of the 0.4mm strip prevent the laptop lid from seating 100% flush, although system sleep triggers remain functional. The dual-sided design provides a choice between a matte diffuser for glare reduction and a glossy surface for maximizing contrast.
To maintain hinge integrity and cable health, technical protocols suggest removing the filter before placing the hardware into high-compression sleeves or using it in conjunction with thick keyboard covers.
Performance metrics confirm a 30-degree privacy cutoff suitable for high-security environments. However, the presence of the filter may increase the surface's susceptibility to fingerprint oil accumulation compared to the native oleophobic glass of the MacBook display.
For users requiring a similar magnetic interface for the 14-inch platform, the PYS Magnetic Screen offers equivalent micro-louver density in a smaller form factor.
This device represents a specialized tier of privacy screens engineered for specific hardware bezel magnets.
