Weird doubled images...see attached images

[Atilla10]

Here are the results...attached 2 images one with 4:3 (1600x1200) and the second one is with widescreen (1920x1080). They both work well, with no problems. On Mac Pro Desktop 2011, Apple LED Cinema Display 27".

This info might be helpful to someone else.

Which image/aspect ratio (4:3 or widescreen) gives the most realistic view (without being stretched out vertically or horizontally)?
