Display Profiles

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).

Now the profile has a higher color temperature which makes is suitable for working through the whole day (not only at night) and simulates paper so the pressure on the eyes is greatly reduced.

Pro Tip: As the Health-Guard profile simulates paper and has as accurate as possible colors, it could be a great tool for prepress designers!

Design and Gaming

The second profile type is Design and Gaming – it combines our previous “Web Design” and “Gaming and Movie Nights” profiles in one, so it’s aimed at designers who work with colors professionally, and for games and movies as well (or maybe you’re a designer who likes to relax with some games or movies from time to time?).

“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.

Just as our previous Gaming profile, this one also regulates the first steps out of black so you can have even faster reflexes when playing in dark virtual environments…or just see everything in the darkest scenes in movies.

Office Work

The third profile is Office Work and it should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing.

Office Work aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

MSI GS66 Stealth (10Sx / 10Ux) in-depth review

Ever since the first Stealth series from MSI was released, the laptop world was baffled and headed towards change. We started seeing a lot of thin and light gaming notebooks, which became better and better as time passed. This is also valid for the GS6X Stealth series. Last year, the design got better, and it looked sleek and stylish, rather than aggressively gamer-ish. Then we fast-forward to today. When the GS66 Stealth series looks like an industrial package, cut from a block of metal. We[...]

Pros

  • Responsive touchpad, Thunderbolt 3, and Wi-Fi 6 support
  • Takes up to 64GB of DDR4 memory and has two M.2 slots
  • The display is PWM-free above 25% brightness (and the frequency of the flickers is high-enough below that) (Sharp LQ156M1JW03)
  • 240Hz refresh rate and quick pixel response times (Sharp LQ156M1JW03)
  • 95% sRGB coverage and great color accuracy + a lot of customization options with the included software (Sharp LQ156M1JW03)
  • Capable hardware inside of a thin, relatively light, and well-built chassis
  • IR face recognition system on board

Cons

  • Lacks an SD card reader
  • The laptop gets pretty hot on the outside during gaming
  • The keyboard is a bit underwhelming, despite its Per-Key RGB backlight
