However, on a purely technical level - it IS distorting the picture, because it's not the same as it was
Because of the extensive processing required, the better the set the more delayed the picture is likely to be - this is obvious if you put different sets on side by side, and turn the sound up one them (the sets automatically delay the sound to match the picture).”

You never said that though.
You said it "merely" makes it fit the higher resolution screen, which would be stretching the image. Merely being the key word which was a bad word to choose.
