p.1 #1 · Any users suffer symptoms linked to PWM with Z8 or Z9 EVF's
Hoping someone might have an insight into this. I suffer side effects from the PWM (pulse width modulation) used on OLED screens in devices such as iPhone 11 Pro, 12, 13 etc. Literally cause me to become mildly dizzy, nauseous, almost like travel sickness symptoms, not pleasant.
I am trying to find if anyone else who suffers with this has managed to use the Nikon Z8 or Z9 EVF's without any issues. It may be I need to try/hire one for a week to find out the answer, if I cannot tolerate them it means I will have to resort to a D850 for now, until maybe the technology changes and some kind of non OLED viewfinder screen is implemented.

I notice PWM a bit more than some, like with LED lighting and whatnot, but it doesn't generally result in any physical symptoms. I did get headaches from my iPhone 13 screen, though.
Anyway, I've not noticed it at all with a Z EVF. But if you're more sensitive to it, then you probably do just need to rent one and use it in a variety of circumstances.

Someone correct me if I'm wrong, but I don't think the Z8/Z9 screen changes refresh rates during different operations like the Sonys do, so that's probably a boon for OP.

While the flashing of cheap LED Christmas lights can drive me crazy 😂, I am not sensitive enough to say if the Nikon OLEDs will be an issue for you or not.
Usually, PWM issues are worse at lower brightness levels. To dim OLED screens or LED lights, a technique is used where the light is turned on and off very quickly, so it appears dim to your eye. Generally speaking, the cheaper the device, the fewer blinking cycles there are per second, which makes it more likely for your eye or camera to pick up the blinking. Then, as you decrease brightness, it exacerbates the lower cycles.
So for anyone running into issues with OLED displays or LED lights, I would try upping the brightness. While not ideal in all situations, it's probably offten a better alternative than feeling ill.
