Sometimes you really do not want people around you to see what is on your laptop screen, so HP has come up with a solution. It has developed a new screen that can cut off viewing angles with the press of a button, making it much harder for anyone on either side of a laptop to see what is being displayed.
The feature works by preventing light from shooting off to the side. That way, when it is active, you should only be able to see the laptop if you are facing more-or-less straight on, within the 70-degree arc right in front of it; 95 percent of light directed to either side of that is supposed to be cut off.
Unlike additional privacy stickers that are mostly permanent and leave you with hard-to-view dark screens even when you are alone, the new HP screens can be switched on and off by pressing a keyboard shortcut.
The feature is called Sure View and was developed in partnership with 3M, which actually sells some of those stick-on filters. Starting in September, the Sure View screen will be available on new HP laptops, including the EliteBook 1040 and EliteBook 840.
