They only work from an angle, so if your back is turned to a walkway, people walking behind you will still be able to see things relatively clearly. Keep in mind a few things about these, though. One way to prevent people from getting a hold of sensitive information is with a physical privacy filter that darkens when viewed from an angle. Identity theft is not a joke millions of families suffer every year. It does, however, install with a simple spring-loaded mount that stops you from having to mess around with adhesive strips. And, despite this high price, it doesn't seem to provide any better protection than low-cost versions, like the AmazonBasics Widescreen. The Kensington Snap2 remains on the list as a strong choice, although it tends to be more expensive than most. It's very dark, which can be a good or bad thing if you're already squinting at your monitor, you might find this version to cause more trouble than it's worth. We selected the Fellowes PrivaScreen, as well. Both models are available to fit a range of monitors, although as with most other brands, it's tough to find a screen made for those exceptionally large ultrawide monitors.Īs for other choices, we added the SightPro Premium on the strength of its UV and blue-light blocking capabilities, which pair nicely with the privacy it offers. We especially like the gold, glossy GF Series, which surmounts some of the clarity issues that plain, black filters can have. In fact, we've kept the 3M GF Series and the 3M PF Series as top choices. Such filters last long, maybe even longer than the computer itself.When it comes to privacy screens that work well and are durable over the long haul, it's perhaps not surprising that models from 3M still come out ahead. The Akamai company's filters are notably sturdy thanks to their thickness. With the gold filter, you can make your screen shine while hiding your confidential data. People note the 3M computer screen privacy filters for their attractive appearance, available either in black or gold. In terms of colour and finish, you can pick either a traditional black or shiny gold sheen, and turn an otherwise glossy computer screen matte with a special filter. Choose a filter with an adherence method that does not leave sticky residue. The application procedure is also vital if you plan to repeatedly remove and reinstall the filter, such as when you want to show something to other people. You can offset this by increasing the screen brightness, but this may lead to reduced battery life. Pay attention to image clarity as the filters dim the screens a bit. Camera lenses and polarised glasses use similar technology. Polarisation is the phenomena ensuring that light from certain angles remains blocked. It is worth checking the shape of the filter, too.Ĭomputer privacy filters are fairly simple devices. However, some displays have curved edges and others are rectangles. At this point, it is easier to follow the general display sizes, given in inches, such as 14 inches. When checking the size of the filter, note that the filter should be big enough to cover the screen entirely. Try measuring your screen diagonally from corner to corner, or check the screen size on the computer's documentation. Although universal computer screen privacy filters exist, you still at least need to match the screen size. However, most require external filters, similar to computer screen protectors that keep scratches and dust off your display.įor a privacy filter to actually work, it must be compatible with your computer make and model. Some computers build this in, allowing you to switch privacy on and off as you please. You can see the contents of your screen, but the person sitting next to you cannot. These filters allow the light to pass through only straight and not on the sides. By adding a special computer screen privacy filter, this task is relatively easy. Keep snooping eyes away from your computer screen, and enjoy your privacy.
