34-inch 21:9 privacy filter for widescreen monitors

This black privacy screen filter fits 34-inch displays with a 21:9 aspect ratio measuring 31.4 inches wide by 13.5 inches high. It uses micro-louver technology to darken the view from side angles between 30 and 60 degrees while keeping the screen bright when viewed head-on. The filter also blocks 96 percent of UV light and reduces blue light by 65 percent to lessen eye strain during long sessions.

Two mounting methods and common fit issues

Installation is simple with the included attachment strips and slide-mount tabs, plus extra kits for both options. The most frequent problem is ordering by diagonal size alone; the filter must match the exact width and height of the visible screen area or it will not cover the display correctly. Ensure the screen surface is clean before applying strips to avoid adhesion failure.

Check your screen dimensions before ordering

Measure the active viewing area of your monitor or laptop screen to confirm it is 31.4 inches wide and 13.5 inches high. Do not rely on the advertised 34-inch diagonal or the 21:9 aspect ratio alone, as bezel sizes vary and can make the filter too large or too small. The filter is designed for flat widescreen panels; curved screens may prevent full contact.

Questions about this item

How do I verify the filter is blocking side views after I attach it?

The pack supplies both adhesive attachment strips and slide-mount tabs, plus spare kits for each method; no extra parts are required.

Which screen size should I pick for a 34-inch 21:9 monitor?

Choose the filter listed as 34 inches with a 21:9 aspect ratio measuring 31.4 by 13.5 inches; match those exact width and height figures to your display.
