LCD do not refresh in the same sense as CRTs. They project a

His problem is probably due to environmental factors. E.g. display
too bright, viewing angle causing neck strain, or eye strain, color
balance/gamma subtly off, etc.
You are obsessed with refresh rate, but it's a useless thing to
focus on, because refresh rate is about flicker, and LCDs don't
flicker.
I have however seen LCD monitors behave significantly different
depending on refresh rate. Entire areas were blury, but everything was
fine when I switched to another refresh rate (60Hz -> 75Hz if I remember
correctly).
I have never owned an LCD/LED monitor that one could change that setting
on. And I've owned quite a few.

Never had that experience or heard of it or dreamt of it.
There do exist bad LCD panels. Blotchy, dim in one quadrant, bad
pixels, pixel memory, ghosting, terrible response time, bad contrast.
