Product information

Description

The Qoltec 51057 privacy filter is made for 58.4 cm (23") monitors with a 16:9 aspect ratio and uses micro-shutter technology to limit viewing angles. The filter narrows the visible screen angle to approximately 60 degrees so information on the display is only readable from directly in front of the monitor. It is manufactured from high-quality LG material and includes an anti-reflective coating that reduces blue light emission while preserving a clear, clean image.

Advantages

The privacy filter prevents side viewing by darkening the screen when seen from an angle, reduces glare and reflections, and protects the monitor surface from scratches. Its anti-reflective treatment lowers blue light emission to improve visual comfort during extended use. The filter is transparent when viewed head-on and keeps on-screen data secure in public or shared environments.

Suitable for

  • Mobile employees working in public places (cafes, airports)
  • Offices and shared workspaces
  • Healthcare, public administration and financial institutions handling confidential data
  • Any 23" (58.4 cm) 16:9 monitor where on-screen privacy is required

How to use

Align the privacy filter with the monitor frame and attach according to the manufacturer’s mounting method (adhesive strips or slide-on fit depending on the monitor). Ensure the filter is centered and free of dust before fixing to avoid trapped particles. Clean the filter surface with a soft, lint-free cloth and a mild screen cleaner as needed; do not use abrasive cleaners or rough cloths. For optimal privacy, view the screen from directly in front and avoid side viewing angles.

Usage recommendations

Use the Qoltec 51057 privacy filter in environments where screen confidentiality is required. Regularly clean the filter with non-abrasive products and check attachment points to maintain full protective and anti-reflective performance.
