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.

So, this is the third year that ASUS is making an ROG Zephyrus G15. If we have to be honest, the previous two iterations were flawed and didn't deserve their users' attention. However, the GA502 (in both its forms) paved the way for ASUS and AMD's relationship. And the result of this is the ROG Zephyrus G15 GA503, which aims to completely revamp our views on the family of laptops.For starters, it now comes with a Zen 3 portfolio of processors, maxing out with the Ryzen 9 5900HS. Also, on the graphics side, you have the latest and greatest from NVIDIA, in the form of three Ampere GPUs. The[...]
