Keep prying eyes off your laptop screen with this built-in privacy filterHP is adding an instant-on filter to a pair of its business laptops.
[MUSIC] Hacking fears keep many up at night, worried about everything from malware to fishing. But it's easy to overlook the most primitive form of hacking, simply eyeballing someone's computer screen while they enter passwords, or read confidential material. If you've ever sat in a crowded coffee shop, or used a laptop on a plane with someone seated in the row behind you It could have already happened to you. A simple privacy filter which makes you screen near impossible to read from a side angle is a simple solution but it requires you to carry around a big round rectangular filter material And it often makes your screen harder to read, even if you're directly in front of it. HP is adding what it calls the world's only integrated PC privacy screen to a pair of professional laptops, the HP EliteBook 840 and 1040. Developed using technology from 3M, the privacy filter is embedded in the Screen itself, but can be turned off and on at will. When it's off, the laptop screen looks as bright and clear as normal, then hit Function + F2 and the privacy filter turns on. The direct view is slightly dimmer as if you have a separate filter placed over the screen, but from the side, the screen is nearly completely blocked out. These two EliteBook models are the first to add this new feature, but it's something that could definitely come to more laptops in the future.
