Thanks for the feedback, appreciate it!
I don't believe the borders are being cut off in any way, but I've realized setting the screen size to full, maybe an inch of the image gets squeezed in from both sides (that wasn't visible before), and I'm simply being able to see more on my TV. It seems everything is tightly packed together even more resulting in a sharper and crispier image, but then I see objects appearing different sizes in the center of the screen, and appearing a bit bigger and wider around the edges. This can be a bit off putting when playing a driving sim like Forza Motorsport 4, where cars don't seem that 'sleek' and 'sporty' in the middle of the screen, but as they move closer to the edges, they appear nice, wide and sleek, and look more up to scale like their real-life counterparts.
However, I haven't noticed any of this in 'normal' screen size. My Bravia is a 2008 model, and in the display/screen settings, you have the option of setting the screen/pixel size to normal (recommended one) or full, which is like you say, 1:1 pixel mapping.
For movies, I always select 1:1 pixel mapping, as I don't seem to notice any unusual effects, but with games, I'm sticking to normal for now, as objects/cars/characters looking up to scale (anywhere on the screen) is very important.
