the big TV, part III

television aspect ratios, accounting for viewing distanceQ: How do you make a 42'' television look no bigger than the 20'' television it replaces?
A: Sit twice as far away.

So, we don’t have that huge theater-screen experience we were hoping for, but at least the couch need not sit in the middle of the room like it used to.

2.35:1 content on a 1.77:1 screen leaves borders top and bottomThe other thing that surprised me about owning a widescreen TV is that some movies are even wider than 16:9. I thought there were only two common aspect ratios for video content — 4:3 (old TVs) and 16:9 (widescreens). 16:9 is roughly 1.77:1… but some movies are shot as wide as 2.35:1. In short, you can buy a widescreen TV, but you can’t fill it.

(Modern televisions have several viewing modes that zoom in on, stretch, and/or squash content to fit the screen. Our plasma even has an innovative mode that only squashes the edges, so that bodies change shape as characters walk offscreen. But I was surprised that a cutting-edge display is essentially already obsolete in this respect.)
