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.

Acer Predator 21 X (GX21-71) in-depth review

You've probably heard about the Acer Predator 21X that was announced way back during IFA 2016 in Berlin but since then, the company has kept the curtains closed around this ambitious project. Until this year's CES when the OEM announced that it will start shipping its first units sometime during Q1 of 2017. Luckily, we had the chance to snatch one of the early samples for a review, but unfortunately, the expected performance wasn't reached when we tested the device. But judging by its coolin[...]
