Your screen has an aspect ratio of 16:10 (because it's a computer screen). All films are recorded with an aspect ratio of 16:9, hence the black bars.
So the moral of the story is to get a HDTV![]()
Not really.
16:9 is pretty much inbetween 4:3 and what most films use which is 2.35:1, that's why TVs are made in 16:9 which is widescreen. Also TV programs are at most recorded in 16:9, I've yet to see one at 2.35:1.
