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.

Dell Inspiron 16 Plus 7640 in-depth review

The Dell Inspiron 16 Plus 7640 shares a lot of similarities with its smaller 7440 sibling, which we also have reviewed. This includes the large variety of CPU options of Core Ultra as well as Alder and Raptor Lake chips. Curiously, the bigger 7640 iteration can be found as an iGPU-only model (with soldered memory) or with a dGPU as well. The laptops with GeForce RTX 4050 and RTX 4060 have two SODIMMs which makes them future-proof.The port selection is decent - the machine with an iGPU boasts an SD card reader while the other devices lack this extra. The backlight and the fingerprint reader[...]
