DOWN TO EARTH TEST:
These picture frames were taken using a Sony CCD, said to be one of the best in its class (23 MP), capable of Full-HD at 100Hz.
Since the shutter speed is ofter higher than the subject refresh rates, bands and black screen insertions can appear in the resulting image, otherwise no bands and/or flicker would be visible.
LG IPS 29' Ultrawide monitor @60Hz (Default).
LG IPS 29' Ultrawide monitor - Overdrived @75Hz.
Thinner and less evident banding observed, due to the higher 75Hz (closer to the CCD shutter speed).
LG curved OLED Tv 55' at 4K , auto refresh rate (Game mode - highest possible setting).
No bands visible and no flicker, image barely had flicker on the camera screen before the shot, so guessing reaches 100Hz refresh or higher.
Also I did a through the lens quick test with Lenovo Explorer, black band strobing was heavily visible at his declared 90Hz default, way much than the LG IPS monitor.
Anyone is free to draw his/her own conclusions, obviously these artifacts are not noticeable to the naked eye in any case, so this will hardly be a big real problem for any of us Pimax fans, but it tells something about some numbers the panels claim.
Will try to test more monitors/panels with the same CCD if I find the occasion to do it, hopefully on a 144Hz gaming monitor.
(A word of advice, only high speed shutter cameras more than 60Hz should be used, and be aware that some phones like the Apple 7's and 8 have a flicker auto cancelling filter that syncs the shutter to the screen area with a same refresh if you're pointing the camera at monitors/Tv's, even if using 120 or 240 frames x second, this could lead to inaccurate results).
