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.

Lenovo YOGA 900S (12″) in-depth review

Lenovo has been polishing its Yoga lineup since its first debut in 2012 and combining all of its craftsmanship into the, what claims to be world's thinnest and lightest convertible. Well, that applies mostly to the high-end members of the series. With a bit of jumping back and forth in a love-hate relationship with Intel's Core m, Lenovo brings back the mobile chip into its flagship Yoga. The Yoga 3 Pro, for example, was a bit of a letdown mainly due to the unsuccessful first launch of the C[...]
