Are idiots like this fucking blind?

I can tell the difference between a 5K and a 4K display easily at a 10 foot distance. Easily. It’s not even a challenge. I could do it with one eye closed and standing on my head.

Of course, that fucknugget isn’t even right because (as a commenter later points out), anti-aliasing and color blending also gets better the more pixels you have to work with. That is a very noticeable difference to nearly anyone, by the way.

That said, in most situations, 8K is about the limit of what I can resolve at normal viewing distances. In certain situations, I think I could tell the difference up to about 30K, but there is no practical reason to ever make monitors of that resolution.

I’ve lived through these debates before. I remember when 800×600 screens started coming out in the late 1980s and there was a huge fracas about how that resolution was unnecessary, was ruining computing, no one needed anything that sharp or that large, etc. Check out Byte magazine, Antic and others from that era if you can find them.
