Acer Predator Helios 18 AI in-depth review

The Acer Predator Helios 18 AI (PH18-73) isn't just a laptop; it's a declaration of dominance. Built for the gamer who believes that "too much is never enough," this 18-inch behemoth packs a staggering array of features into its massive chassis.

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.
