Hang this universal 23.8" 16:9 aspect ratio Monitor Privacy Screen on the top edge of a 23.8" monitor to obscure the view of sensitive on-screen information. Silicone bumpers ensure a secure and damage-free application. The hanging security filter is a convenient solution that protects confidential data from unwanted viewers while maintaining a 60 degrees (+/- 30 degrees from the center) clear view for the user. The hanging design allows to mount the protective screen with ease or quickly remove it when privacy is not needed or when sharing content with a trusted audience. The privacy shield provides a 65% light transmittance, delivering optimal screen brightness with enhanced levels of privacy. Apply the included silicone bumpers to provide a firm grip to hold the acrylic frame secure from the top of the monitor, and to keep it from touching the screen. Reduce eye strain and improve visual comfort by reducing blue light exposure. The computer monitor filter blocks blue light emitted from the display, decreasing exposure and improving visual comfort.
