But I'm also wondering if a larger part of it comes from within (our brains) via expectation/accustomisation. We are so used to "watching" TV that we make automatically make allowances for the medium. View a picture made up of 1024 x 768 dots on a screen and we "see" the scene it should depict. Print out the same image faithfully to hard copy and we see the dots: we are accustomed to reading very high resolution images / text in magazines. Daft idea? Well, such a phenomenon is well known for audio signals where people who have heard a tune on a decent system hear more than is there when they hear it on a badly distorted weak radio signal. The mind fills in the gaps ... All just speculation. Bob
