STARTECH 38C29-PRIVACY-SCREEN 38" accessory for Dell U3824DW 21:9 monitor

Privacy screen for 38" Dell ultrawide

This privacy filter is built for the Dell U3824DW curved ultrawide monitor with its 21:9 aspect ratio. It limits the viewing angle to roughly 60 degrees, so only someone sitting directly in front can read the display. The screen attaches to the 38-inch panel and suits professionals who handle confidential data in open offices. It also serves anyone who wants to reduce shoulder-surfing risk during long work sessions.

Viewing angle and light trade-offs

The filter restricts visibility to about 30 degrees either side of centre, which means collaborators standing slightly off-axis will see a darkened screen. Light transmittance sits near 60 percent, so brightness drops noticeably compared to an unprotected panel. Blue-light output is cut by up to 51 percent, which can ease eye strain during extended use. Users who need maximum luminance or wide sharing angles will find the screen limiting.

Double-sided finish and daily handling

A matte coating on one side cuts glare from overhead lighting, while the opposite glossy side preserves colour vibrancy when reflections are not an issue. The filter mounts directly on the curved 38-inch display without additional hardware. Its black frame blends with the monitor bezel for a clean look. The reversible design lets you flip the screen to match changing light conditions throughout the day.
