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.

ASUS K751LX in-depth review

ASUS is famous for rebranding some of its notebooks by using the same chassis and thermal design, but labeling it as another product with a different paint job. The case with the K751LX is basically the same. It comes as a bigger sibling to the previously reviewed K550JX, but with a notable difference - it has a dual-core Core i5 or i7 CPU (depending on the configuration) instead of the speedy quad-core Core i7-4720HQ found in the K550JX. Anything other than that is almost the same, except for t[...]

Pros

  • Comfortable keyboard
  • Well-balanced hardware with particularly powerful GPU for the price tag
  • Excellent cooling system
  • Three USB 3.0 ports
  • Relatively high resolution (1600x900) and sRGB color gamut coverage for its class (79%)

Cons

  • The CPU bottlenecks the gaming performance slightly
  • PWM from 0 to 99% screen brightness with aggressive light pulsation (200 Hz)
