I generally find that my laptop screen is too bright anyway and frequently adjust it downwards. To me, a dimmer screen isn't a huge trade-off for increased privacy. Viewed from an angle, all I could see was my own reflection in the Elite Dragonfly's glossy display. The only drawback is a dimmer screen, with contrast and colors otherwise appearing identical to how they look with the filter turned off.

That early version was revolutionary in that it enabled privacy at the tap of a button, rather than having to attach an external physical privacy filter. I tried SureView Gen 4 during a brief demo at CES, and I found it to be a vast improvement over the first-generation SureView privacy filter, which showed up on HP EliteBooks in 2017. At a 45-degree angle, it blocks 99.7 percent of the screen's viewable contents, but it hardly affects the screen quality at all when you view it head-on. Called SureView Gen 4, its brightness can automatically adjust based on the angle at which you're viewing the screen. The technology will show up first on the HP Elite Dragonfly G2 laptop, unveiled at CES this week. The company, which has also created privacy filters for phone screens, built a new laptop privacy filter that harnesses the display's natural glare to obfuscate it from extreme angles. But a startup called RealD ME wants to change that. So hey're mostly available on business laptops like HP EliteBooks and Lenovo ThinkPads, whose users deal with extremely sensitive information. Why? They can significantly degrade picture quality, washing out colors and dulling text. But privacy filters integrated into a laptop's display to guard against someone snooping over your shoulder aren't nearly as prevalent. LAS VEGAS-Integrated webcam covers have become ubiquitous on laptops as a way to guard against a snoop hacking the camera and spying on you. Privacy protector laptop how to#
