Physical privacy is becoming a key point of concern among many people and organizations, which is why hardware makers are addressing concerns of their customers by incorporating various technologies into their products. To that end, next month HP will start selling its EliteDisplay E243p Sure View Monitor that, as the name suggests, features the company’s on/off Sure View privacy screen tech.

Aimed at corporate environments, offices, and public services where shoulder surfing is a practical risk, the EliteDisplay E243p Sure View monitor's primary selling point is the integrated, user-controllable Sure View privacy screen. Designed to deter off-angle viewing, the privacy screen relies on HP’s proprietary technologies as well as 3M’s optical films. Once Sure View is activated, the display reduces its brightness to 180 nits and horizontal viewing angles to 80°, thus hiding sensitive data from prying eyes of passerbyes or hackers.
