Here is a Dr Geep graphic on what I'm saying...

Which brings up a more important effect of non-square screen sizes:

When I set my right monitor to make the above graphic to 1280 x 768, I made the first circle round, then rotated a copy of it 90 degress in Photoshop. However, when I brought the picture into the left monitor (still running a "square" 1280 x 960) neither circle was round, one was a tall oval, one a wide one. Graphics are a set number of pixels, the result will change due to what the pixels actually measure.

So, if you are running a non-square pixels (which would be whenever the physical size of the display doesn't match the pixel ratio, it doesn't have to be 4:3, that is only the "normal" size) AND what you produce is shown on another, "industry standard" square pixel display the result is going to be too tall or too narrow, got what I'm saying? ;-)

We need to produce "standard" graphics (gamma factor too) if we expect our pictures will look as intended on other computers.
