Health-Guard
The first and most important profile (in our opinion) is the Health-Guard – when being used with our LM Profiles application, Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body.
Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate (they may seem strange at first but after a few minutes our brain will start recognizing them as accurate ones – that’s how Health-Guard differs from alternatives like f.lux).

Office Work and Web Design
The second profile type is Office Work and Web Design. Business tasks are various, most often related to a set of office-targeted applications. Sometimes, working outside is necessary. In such cases color accuracy is paramount, but so is image clarity, brightness, contrast etc. A piece of text must be legible, graphics and histograms must be clear. All of this is precisely what this profile is for. If you’re doing office work, web design, or simply value color accuracy when browsing the Internet, this is the profile to use!
It’s important to note that not all displays are suited for Web design – our profiles can not compensate for insufficient sRGB coverage (most TN panels have this problem), so you you might want to check our detailed color tests in the respective product reviews we’ve done if you want to use the machine for professional work.

Gaming and Movie Nights
Gaming is among the main driving forces for the fast clip of hardware development. Gamers are well-aware of the fact that a poor image can ruin the entire experience.
The same goes for watching movies. Imagine sitting down for a nice movie after a long day, and barely making out what’s on the screen. The ‘Gaming and movie night’ profile can make a huge difference. We strongly recommend you use it, since it’s gamma curve is specifically tuned to reveal details in the dark sections of the image.
Here’s what this amounts to:

HP ProBook 450 G4 in-depth review
HP's ProBook lineup has been praised for a number of reasons in the past and now we will have to assess the next generation ProBook 450 G4 and see if it holds up to the legacy of ProBooks. In most aspects, the ProBook G4 keeps what's good from the previous version while offering slight changes here and there. Hopefully, most of them will turn out to be good but one thing is for sure - the upgrade to the newest Kaby Lake generation of CPUs will be more than beneficial. However, this has af[...]
