Keep on-screen information private
The Dell Privacy Filter offers a clear view from the front and provides effective “black out” privacy from the sides. Keep others outside the 60-degree viewing angle from seeing what is on your laptop screen, without blocking your own view. Attach the privacy filter on a high resolution screen without compromising on screen clarity.
