Surprisingly, it's not wrong. 1366x768 is chosen because it's just under a 
megapixel and (so I'm told) is suitably cheap for TV manufacturers to use.

The reason why you're losing pixels either side: modelines must be set up as 
multiples of 8 pixels, hence 1360. I forget the reason, it's probably to do with 
shuffling things in and out of registers on the video card.

3 pixels either side is neither here nor there. If you're that worried, why not 
select overscan? That way you'll get your 6 pixels back (but you'll lose them 
off the top and bottom instead :).
