Yeah, I bought the Galaxy Tab S8 2022 and my eyes are bloodshot after a few hours of using it, so it is going back.
We will never solve this issue if it is completely individual how each person's eyes get irritated by each device.
I still have the Lenovo x280 that I can use 10h a day without any discomfort or patching. It does not cause any discomfort it it's own display or when connected to HP LCD display that does not have PWM.
All other displays that I have currently, require me to put tape on my right eyeglass to not cause bloodshot eyes.
