I wanted to see something and clicked on the 120Hz version not knowing what my laptop display actually is and while I am not photosensitive this was quite uncomfortable. Thinking I don't understand what that is supposed to be I clicked on the 480Hz to see if that is better/different and that was even worse. As a hail mary I clicked on the 240Hz and well that really made sense and was actually comfortable to look at.
So if you are like me and didn't really read through the text, this will only work for you if you select the Hz that matches your display ( which kinda is the whole point of why they are doing that ). If it looks bad you clicked the wrong link
