19-Inch Monitor Privacy Filter with Microlouver Technology, Anti-Glare Matte Finish, and Blue Light Reduction for 5:4 Standard Displays
The 3M PF190C4B is a standard privacy filter for 19-inch monitors with a 5:4 aspect ratio. The filter blacks out the display from side views beyond a 60-degree angle using 3M's microlouver technology, preventing visual access to on-screen content from anyone not seated directly in front of the screen. The PF190C4B fits a 14.83 in. x 11.89 in. viewing area and includes both adhesive strip and slide-mount tab installation options. The matte-finish privacy filter reduces glare and fingerprint visibility while providing blue light reduction to lower eye strain during extended monitor use.
The PF190C4B features a matte surface on both sides for consistent glare reduction regardless of which side faces out. The 5:4 format fits the standard (non-widescreen) 19-inch monitors still widely used in healthcare, finance, government, and point-of-sale environments where square-format displays remain the standard. Slide-mount tabs let you remove the filter when needed and snap it back into place without adhesive residue. Scratch-resistant and fingerprint-resistant construction handles daily use in shared workstation environments. Made in the USA with a 1-year limited warranty.
Where the PF190C4B Fits
- Healthcare workstations and nursing stations where 19-inch 5:4 monitors remain standard for EHR systems and HIPAA compliance requires visual privacy controls on all displays showing patient records and protected health information
- Financial services and government offices where legacy 5:4 monitors display account data, case files, and personally identifiable information that must be shielded from unauthorized viewing in open floor plans
- Point-of-sale and reception desks where customer-facing 19-inch monitors show transaction data, inventory systems, and employee-only information visible to anyone standing at or near the counter
What the PF190C4B Delivers
- 60-degree privacy with side blackout: Microlouver technology transmits a clear image within a 60-degree cone directly in front of the screen. Outside that angle, the display appears black, preventing visual hacking on standard-format monitors.
- Dual matte finish for glare reduction: Matte on both sides to reduce glare from overhead lighting and bright environments. Fingerprint-resistant surface stays clean through daily handling in shared workstation setups.
- Adhesive strip and slide-mount installation: Slide-mount tabs grip the monitor bezel for tool-free removal and reinstallation. Adhesive strips provide a semi-permanent option for dedicated workstations where the filter stays in place.
- Blue light reduction without color distortion: Reduces blue light emission from the display to lower eye strain during extended use without shifting on-screen colors or affecting display accuracy.
- Sized for 19-inch 5:4 monitors: Covers a 14.83 in. x 11.89 in. viewing area on standard 19-inch monitors with a 5:4 aspect ratio. No trimming required for properly sized displays.
How Do You Measure a Monitor for a Privacy Screen?
Monitor privacy screens are sized by the diagonal measurement of the viewable display area, not the outer bezel or cabinet. For a 5:4 monitor like the 19-inch standard format, the viewable area measures 14.83 in. wide by 11.89 in. tall. Measure corner to corner across the screen surface to confirm the diagonal, then match the aspect ratio (5:4 for standard, 16:9 or 16:10 for widescreen). The 3M PF190C4B is designed specifically for 19-inch 5:4 displays and will not fit 19-inch widescreen monitors, which require a different filter with wider, shorter dimensions.
