Reinhard62 Lots of PWM-free devices cause people eye strain as well.
Is the OP using his tablet in a bright environment? That should great help.
Keep this in mind. There are literally billions of PWM OLED smartphones sold and used. Right? I mean consider how popular are the Samsung, Google, and Apple phones.
MOST people don't complain. They use them fine. They even leave on adaptive brightness and let the display get very dim with high PWM when used in dark coffee shops or elsewhere.
Even atrocious PWM still has a relatively high frequency.
Remember the days of 60-75 Hz CRT monitors? Not the same as a digital technology where the modulation is worse, but no one saw or felt flicker at 100 Hz, and therefore in theory even 240 Hz PWM with bad modulation shouldn't be too bad for most people?
Also, what about letting your body and brain adapt? If I haven't gotten on a bike in 10 years I'm not going to be able to ride it nearly as well as if I ride it every single day. Isn't it very possible the body needs some time to get used to something foreign?
A number of times I've taken a supplement and the first dose or first three doses in one case has caused adverse effects, and yet after that the body was able to know how to handle the new ingredients and no issues were experienced. That's just one small example of countless many I could use as examples.
I was talking with an agent at my carrier, and he told me he uses his iPhone 16 Pro Max for 10 hours a day. No eye strain. Sometimes headaches, but he thinks that's not from the screen, and likely the headaches are mild or else he would have been more vocal when I asked him about it. He uses blue light computer glasses to help.
Then you get people on communities like this where nothing seems to work, with many reporting they can't use many screens even for 5 minutes.
So what differentiates those here from the billions of people who using daily, excessively, PWM devices with bad modulation? I mean you get people on here where a simple software update renders a device unusable.
