In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. 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.


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. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

MSI Modern 15 (B12Mx) in-depth review

MSI is really trying to promote the artists that help with the creation of their laptops. In this case, the company has paired with Lorraine Sorlet, who has absolutely nothing to do with the performance of the device. However, she has created some really "graceful" artwork to compliment your Modern 15 (B12M).What we, nerds, are more interested in though is numbers, scores, and results. Let's start with the first one - up to Core i7-1255U, which has 2 P-cores and 8 E-cores. This is one of Intel's latest ULV processors, which should make a big disturbance in the mobile force.As you can [...]
