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:

Office Work - screen profile

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming - screen profile

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.

HP ProBook 640 G3 in-depth review

Looking at the new HP ProBook 640 G3 reminds us of the good old ProBook 440 G3 that we reviewed a while back which is probably a good thing until you look at the price tag. The pricier ProBook 640 G3 offers little improvement and a tad more features than its more affordable alternative but most of you wouldn't really notice the difference. That's why we would like to help you out with your purchase and see if the notebook is worth your hard-earned money. The ProBook 640 G3 aims at the mor[...]

Pros

  • Good build quality
  • Great input devices
  • The display has high brightness and decent sRGB coverage for a TN panel
  • Outstanding battery life
  • Plenty of I/O, including 4GB LTE connectivity

Cons

  • Display with limited viewing angles, extremely low contrast and inaccurate color reproduction (our profiles take care of the latter)
  • Aggressive PWM (200 Hz) (our Health-Guard profile fixes that)
  • A bit hefty for a 14-incher
  • Pricier than the competition
  • The M.2 SSD obstructs the insertion of a 2.5-inch HDD/SSD and vice versa
