Security and privacy are as important as ever in 2017 with public awareness of protecting online information making headlines daily. HP already ships plenty of security systems in its business line of laptops including Sure Start to protect the system BIOS and Sure Click for web browsing. Another new option to help prevent onlookers from acquiring personal or proprietary information a.k.a. "visual hacking" is HP Sure View. The HP EliteBook x360 G2 is now shipping with Sure View technology, and I've spent some time it. Here is what it does and some surprising findings.

HP EliteBook x360 G2 I've already reviewed the EliteBook x360 and it's my favorite productivity laptop. The 2-in-1 Ultrabook has an excellent keyboard, Microsoft Precision touchpad, a long-lasting battery, and a handy Wacom-based digital pen.

Sure, the EliteBook's larger bezels and mere full HD display will be off-putting to prosumers, but HP puts a lot of unique technology into the EliteBook x360 that makes it an attractive option for those who need a reliable work machine. Of course, none of this is particularly cheap, either. Starting at $1,329 for the Core i5 variant the EliteBook x360 with a Smart Card reader, Core i7 processor, 4G LTE modem, 1TB storage, and Sure View can push $2,900 at the high-end. For enterprise, however, that cost may well be worth it for all the protection and business-focused features. As a prosumer myself, I just find it to be an outstanding computing experience. HP Sure View – What it is If you were doing some work on a laptop in a coffee shop or flying on a cramped airplane the idea that someone could be looking over your shoulder is likely familiar. Most people may not be bothered if just reading a news website, but if writing a sensitive email, reading work documents, or typing a password that fellow passenger next to you is suddenly suspicious.

Previously, the workaround for visual hackers – a quaint term for those who just watch what you're doing – was to physically place an opaque "privacy screen" over your laptop's display. While it certainly worked it also means you either to use it all the time (which decreased visual acuity when not needed) or you had to carry it with you.

HP partnered with 3M to build this technology right into its displays for the first generation of Sure View. That first gen Sure View was released a year ago with the HP EliteBook 840 as well as the EliteBook 1040 notebooks. The new EliteBook x360, however, is developed by HP alone and fundamentally changes how the technology works with an all new proprietary architecture. The digital version of the privacy screen means that with a touch of a button you can turn it on or off whenever you needed it.

How the older first generation Sure View worked. The new generation of Sure View operates differently with an improved effect.

To the user, the EliteBook x360's full HD display appears like any other, with no visual downgrades. But when you press the F2 function key, all three components kick in reducing up to 95% of visible light in the privacy region. The privacy region is defined as outside the user's 70 degree viewing cone, which is illustrated below:

When looking at the EliteBook x360's display with Sure View enabled you'll see a slight opaqueness, but it's nowhere near enough to stop you from doing your work. Side-viewing snoops, however, will see nothing but a washed-out display. Surprise! A 120Hz screen! Earlier I noted there is no visible difference when Sure View is disabled on the EliteBook x360 compared to the non-Sure View model. That's not entirely accurate, but this change works in favor of HP Sure View. In addition to the privacy features, HP is using a high-refresh IPS display that clocks in at 120Hz. For gamers, that is a high-end feature to look for when purchasing a gaming laptop or screen. For Ultrabooks, however, it is nearly unheard of as most standard IPS displays are at 60Hz refresh rate.

The 120Hz setting for the EliteBook x360 with Sure View.

This means that the EliteBook x360 with Sure View has twice the refresh rate as typical Ultrabooks in this category. The result is Windows 10 OS and app animations are much smoother and fluid. It's akin to the "soap opera effect" with TVs (though for different reasons). This change in refresh is very noticeable too with the Windows Action Center, Cortana, and especially browsing in Edge showing twice the animations due to the doubling of the refresh rate. Dare I say, it feels like macOS at this level. This is the first 120Hz panel in an Ultrabook I've seen, and now I wish more companies would do this. Even for Microsoft the Surface Pro and Surface Laptop would be on a very different level were they to institute a higher refresh rate. The display is locked at 120Hz, so you cannot change it to 60Hz using the Intel Graphics Settings app. Not that you'd want to. What about battery impact? HP claims that when using Sure View for 50 percent of the time there is "no material difference in battery life." Using it more often, it can take up to an additional 15 percent of your battery. In real world terms, if you left Sure View on all the time I estimate the battery difference to about 20 percent. Considering the EliteBook x360 is only powering a full HD display and already gets near 10 hours of longevity, pushing 8 hours with Sure View seems acceptable. I assume too that the higher refresh affects battery life, but it's mostly minor. After all, the backlight of the display panel is what draws the most power. On the other hand, if doing intense gaming – which is not what the EliteBook x360 is designed or sold for – then the CPU and GPU could be doing more work. The shorter answer, however, is the EliteBook x360 with Sure View felt like the regular version with no tradeoffs. What's the cost of Sure View? It should not be surprising that choosing the "13.3-inch diagonal FHD (1920x1080) LED UWVA ultraslim Touchscreen with HP Sure View Integrated Privacy Screen" option during checkout versus the non-Sure View version will cost more. However, at just $111 it is not exactly a wallet-busting upgrade, especially when you compare it to the $718 upgrade fee to go from 128GB of storage to 1TB. Currently, HP has the Sure View option only listed under the "customize" listing on its site. The extra cost would be a consideration if HP were to push into its consumer line of Spectre laptops. Luckily, HP seems able to handle making such components as configuration choices ultimately letting the customer decide instead of forcing it on them. The Bottom Line: The future of physical privacy Overall, I'm quite impressed with HP Sure View. In an age of hacking and privacy, it is a useful feature for business and government industries, but I also see this as a viable option for prosumers who want protection as well. The only downside I see is the cost, which is not prohibitive compared to other PC upgrades. Also, right now the Sure View display is only available in this 1080p option on a handful of HP laptops focused on the business crowd (which tends to focus on reliability over high-end specs like a 4K display). When Sure View will be available on 4K displays is currently an open question.
