I see comments like this sometimes and wonder if people are born with super eyes or something and I missed out. I only notice the difference between the various HD standards and standard def if they're put right next to each other, don't even bother owning a monitor with >1920x1080, etc.

I promise you it's just as baffling to me that some people don't notice it! It seems clear as day to me and I don't even have great eyesight. Maybe it's something like font kerning where it's hard to notice but also hard to un-notice?

Here's an example, can you not see the difference in sharpness clearly?

If I flip between them I can see a difference, yes, but it doesn't exactly make my eyes bleed. Opened up a random PDF in Sumatra without something to compare it to and, now having seen it, still nothing jumps out. Then again, I grew up with bitmapped fonts in 320x200 on a CRT.
