hi all,
I did check for existing threads, and this one is similar, except different... allow me to explain..
I have suffered with headaches on some devices, and previously arrived at the theory it's to do with PWM on OLED displays (mostly phones) that cause my issues. That certainly seems to fit when I look up the PWM rate of the devices that 'work' for me and ones that don't. (examples below).
However.. there are a couple of examples that disprove this theory which is annoying because it's difficult to know which products I can tolerate and which I can't..
Below is a list of displays that I'm fine with, and ones I'm not, and their PWM rates if I could find them.
You'll notice that I can use the Oneplus 8 Pro just fine, despite the fact the iPhone 12 Pro (which has a higher, less problematic PWM rate) kills my eyes.
Looks like Notebookcheck got the PWM value wrong, after looking here: Flicker, the display affliction - which means all the phones make sense.. but the BenQ monitor still doesn't!
I also thought it might be to do with refresh rate of the actual display, but all of the Samsungs in the list that don't work for me are 120hz, so that's not it either.
The BenQ monitor (on the list below) I've just bought has NO PWM at all, and has given me a headache using it for less than 10 minutes.
I have an optician's appointment booked to double check everything, but (anecdotally from others) hasn't produced much joy.
What IS going on?? The only 'safe' tech for me seems to be IPS. I've never had a problem with any IPS screen, however my current phone is the Pixel 5 and I can use that without any comfort issues for hours a day.
Any advice gratefully received
Displays that are all fine
LG monitor 27" (IPS) 27UL850-W
iPad pro 2018 11" (PWM 0 as it's IPS)
Acer K242HQK monitor
LG 65UN85006LA
Surface Laptop (IPS)
Displays that are too uncomfortable to use
BenQ EX3203R
Smartphones that are fine
iPhone 11 (PWM O as it's IPS)
Oneplus 8 Pro (PWM258 481) corrected this as I think Notebookcheck got the PWM value wrong
Google Pixel 4 (PWM 367.6)
Google Pixel 5 (PWM 367.6)
Redmi X50 Pro (PWM 368)
Smartphones that are too uncomfortable to use
iPhone 12 (very bad) (PWM 226.2)
iPhone 12 Pro (PWM 277.8)
Samsung S20 FE 5G (both Exynos and Snapdragon variants) (PWM 227.3)
Samsung Fold 2 (PWM 219)
