I just purchased a new MacBook Pro 15 (2018). I got it up and running how I like (upgraded from a Retina MacBook Pro). Yesterday I used it for the first time to do work and was on it for around 5 hours straight with normal breaks. Mostly email and some software management. Afterward I went for my regular walk/jog in the park, and I experienced what I would describe as an eye-brain disconnect. Sort of alarming and generally less stable, but still functional. Not so much like a headache, but new to me. I believe I am vaguely susceptible to PWM backlight dimming and its potentially negative side-effects, but I've never had a computer monitor that had PWM. I did have an older OLED phone that had PWM and got consistent headaches, and switched to an LCD phone after discovering what PWM is. I did a little research into the MacBook Pro's PWM dimming, and it seems to be the quickest on the market and supposedly imperceptible to even sensitive users (some Windows laptops have more noticeable PWM dimming frequency). So I assumed I wouldn't be affected. Has anyone else had similar issues? The eye-brain disconnected feeling?
