I agree with Leo-j that "sometimes HD looks better than what it really is."

You can put that in your Sig! xD

The human eye perceives about 3000 megapixels at most.

Yes.... but there is also a good deal of redundancy in the system which means the 'resolution' would never actually be that.  Depending on the part of retina, it may take stimulation of many of the photoreceptors to cause firing of the associated nerve, which still doesn't necessarily guarantee that the brain will tell us we have 'seen' something.

I can't recall the source but i remember reading that 1080p is not a accidental number but rather that the ~2 million pixels represented produce an image that can not be significantly improved upon (in terms of resolution) for the size of TV's likely to be found in people's homes.  That is to say we could double the resolution for the 'average' 40-50 inch flatscreen but the improvement registered by the human eye would be minimal.

We are not made of data

^ lol

Real life = ∞p

Reallife must not be that high of a resolution, because I swear I can see jaggies on the edges of my wall corners.... or maybe they really are jagged edges...

@_@

you mean burn our very eyes? =O

For me:
Without glasses= SD
With: HD

Well if you find a TV screen that you can put a microscope against and see the atoms in an object which is on screen then it would match real life.
