Display Profiles


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.

Dell Inspiron 15 5551 in-depth review

It's time to shed some light onto some of the budget models from Dell and we've prepared a relatively new notebook launched just within a month. We are referring to the Inspiron 5551 that aims to be sold mainly to business customers without wanting to spend too much on the device. The price is modest, just like the hardware it offers, yet the design feels way better than expected.You can easily see the resemblance to the Latitude E5550 as the Inspiron 5551 carries the same design signatu[...]

  • Overall appealing design and it's relatively thin and light
  • Good keyboard
  • Harmless (without screen flickering above 25% brigthness) energy-efficient TN panel
  • Great battery life
  • The system handles high CPU and GPU load with ease without throttling or excessive heat


  • Better CPU would have done wonders
  • Poor touchpad performance
  • LAN port missing
