I understand that there are a couple of threads already opened in forum discussing about screen flickering on Kobo Forma.
The purpose of this thread is to share how I tested my unit and hopefully someone can enlighten me if there is any better way to test (not requiring scientifically high-precision-advanced tool).
Also I'm curious how other forma users test their unit (if there is any testing done
) and what is the result?
I tested using Iphone 7 Plus recording slow-mo video @ 240 fps.
Testing was done in a room with various lighting condition i.e. very dark, dim, well-lit with artificial light, and well-lit with natutal light.
Also, the screen was tested on different light intensity from lowest to highest and in-between. Also the kobo was set to both potrait and landscape orientation.
As a result, I couldn't see any flickering at all. Does it mean there is no PWM?
Part of me says I could be one of those fortunate to get non-defective unit.
Like Kobo Clara HD model, while many users reported light-bleeding issue, my unit is does not suffer from this and I'm very much enjoying it.
