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.

Health-Guard - screen profile


THealth-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. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

Dell Precision 15 5520 in-depth review

The XPS series from Dell have been praised for their extraordinary design, build quality paired with performance. This has been proven to be a successful approach to the premium business segment and looks like Dell wants to bring the same concept into its professional mobile workstations. With the Precision 5520 (and its predecessor, the 5510), it's clear to see that the lineup is receiving the XPS treatment and that's probably a good thing. Although the XPS 15 and the Precision 5520 look[...]

  • Premium all-aluminum build with carbon fiber base
  • Thin, light, portable chassis
  • Good input devices
  • Excellent IPS display (conditionally suitable for color-sensitive work) - high peak brightness, extremely high contrast, wide sRGB coverage
  • The panel doesn't use PWM for regulating screen brightness
  • Outstanding battery runtimes


  • The cooling system can't withstand heavy workloads for long periods of time (near 100% CPU and GPU usage)
  • Pricey
