I went to return an item today and looked at a few devices to gauge what I am capable getting should my devices fail anytime soon. the iPad Pro 12.9 really makes me feel terrible. It's extremely noticeable. I then went to the Surface Pro 8 and I created a thread about that earlier. While it felt well, better, I wasn't excited about it. To my surprise, I passed the Galaxy Tab S8 plus and ultra and while they colors are saturated, I was able to stare at the screen without any immediate symptoms. I was and still am shocked. its an AMOLED panel vs OLED if that makes any difference whatsoever. The regular S8 is an LCD I believe. I won't jump to any conclusions just yet, but maybe Samsung is on to something with their color handling, flicker, and/or whatever else it is that causes me harm (with these specific devices).
I feel its worth a try for anyone who hasn't viewed them to find them in store and see how you feel. I know it won't help everyone as we all may fit into different categories but thought I'd share.
