KDL-32EX302? That is the only entry-level 32" Bravia I could find; the  
other 32" models are all "Full-HD", i.e. 1080p. There might be other  
models available where you live though.

It does not display 1080i either, it just accepts (and downscales) such  
input signals. The 32EX302 accepts 1080p as well, but not on all inputs.

No.

That is the actual resolution of the display panel, and thus the upper  
limit of what the TV can display.

No, the limit is in the panel itself.

Yes, downscaled.

If the image is larger than 1366x768, it gets downscaled. You might not  
notice any lack of detail, because the images you are looking at are not  
very big to begin with, but they do get downscaled.

The limit is indeed physical; it cannot be exceeded.

Anything larger gets downscaled. There is no way around that.
