Bezel management makes the bezels less jarring on your peripheral vision by making it so that it's like the bezel is simply covering part of the image (like the pillars that hold the windscreen in, in a car) rather than having a 'void space' where the image stops, then starts again at the exact point it stopped, but an inch or two over.
It makes quite a difference to immersion, even though in theory you're 'missing' some image.
Needs to be experienced to understand completely, though.
I'll try to come up with a diagram. Hang on.
edit: OK, here's an example. Can you see the picture displacement on the peacock feathers caused by the lack of bezel management? Some people are more sensitive to it that others, and while it's noticeable with a still picture, it's way
more noticeable when the picture is moving...Edited by Paradigm Shifter - 9/29/09 at 5:18am
