IIRC TVs use pixels a bit taller than square. 320x240 fills a 4:3 screen on
a computer, but it looks like 352x240 is required on a TV [1]. So TV pixels
are 320/352 = 10/11 the width of a square pixel, or 11/10 the height of a
square pixel, take your pick. So your 1280x800 screen should look 11/10 - 1
= 10% too narrow, or 1 - 10/11 ~= 9% too tall on a TV. Is that about right?
