You are right, others have told me the pixels are rectangles. It may be touted as widescreen, but not specifically touted as 16:9.
The easiest way there is to find out if they messed with people is to display a JPEG of a circle or a perfect square. If you see an oval or a rectangle then you know, but I tkink they only stretched it a little, so many may not notice. It's a convenient way to hold costs down, but I don't agree with it. The real mystery is why you don't read about this in professional reviews.
Thanks for the info, it made it easy to rule out this unit.
