It's the physics-biology interface. Which is complicated, but testable. "BUT IT'S OBVIOUS!!" is not science. Quote:
I have no doubt that knowledge of its existence can have a psychological effect, and there is very good evidence for the nocebo effect as a phenomenon. It would take some good science to winkle that effect out, and I've seen none. Last edited by meeera; 01-14-2020 at 09:05 PM. |

What appears to being said is that the Forma uses 1KHz PWM. So far I haven't seen a study that shows any effect from PWM at that rate -- the highest rate I saw in a study was one that showed a small percentage of the participants could notice artifacts from PWM at 400Hz in saccade (rapid eye movements). One of the tests involved a single dot on the screen which seemed designed to maximize the ability to detect any effects. Looking at quite few of the original complaints, they seemed to involve Samsung AMOLED phone screens. The majority of those early screens used PWM rates below 100Hz. For example, the Samsung A10 which uses a 77Hz PWM rate. Not taking the PWM rate into account is similar to arguing that since I can see flicker in a 10fps video, I should be able to see flicker in a 200fps video. After all, they both have flicker. Quote:

And vice versa... People may have voted no, still have eye strain, and believe that the eyestrain is not caused by the flickering. I interpret the poll as taking the flicker as a given (whether you can see it or not). |
