Lenovo Ideapad 310 with virtually harmless display (PWM report)

lenovo-laptop-ideapad-310-15-front-windows-2-1Interesting results just came in from our lab when testing the Lenovo Ideapad 310 – an entry-level notebook with compelling features and design but falls behind a little in terms of hardware. Anyway, this article is about the PWM, which is present in the display from 0 to 99% brightness. However, there’s a big catch here.

You can find some of the available configurations of the Ideapad 310 here: http://amzn.to/2dksHpb

You remember that the higher the frequency of the emitted light, the better, right? That’s because when the screen flickers too fast for the human eye to record the cycling effect and making it less and less harmful. And this is exactly the case with the Lenovo Ideapad 310, at least with the HD (768p) version. It uses an LG LP156WHB-TLB1 panel that uses PWM from 0 to 99% brightness but the frequency of the emitted light is high enough (read that “extremely high”) not to bother users with super-sensitive eyes. We are talking about flickering at the whopping 43 kHz and we think that there’s a very small number of users who will feel the usual negative effects of the PWM.

Stay tuned for the full review of the notebook in the following weeks.

There should be more medical studies done of which frequency is best, etc.

Happy to see more flicker free laptops.

Could you tell me if the monitor has 50hz refresh rate (although 60hz should be more suitable)? From what i’ve read some users complain about poor quality and flickering issues.. that’s why i’m not quite sure buying it
