    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

    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.

    ASUS Zenbook DUO (UX8406) in-depth review

    The UX8406C version is almost the same device as the Zenbook DUO (UX8406). The main difference between the two is the CPU platform. The UX8406C is based on the latest and greatest Intel Core Ultra Series 2 processors which are also known as Arrow Lake. At least for now, you can choose between the 45W and highly clocked Core Ultra 9 285H and the 28W Core Ultra 7 255H. The latter has the same core count and cache size as the 285H chip which makes it a perfect choice for people who don't require top-end performance for everyday tasks and want to save some money.Both CPUs have the same iGPU un[...]
