Now this is a rather strange thread, and after taking this picture of my friends Panasonic plasma widescreen TV last night, and using my own copy of Star Wars Episode III: Revenge of the Sith. Note the sides of the image on the top, this is the Panasonic plasma.
And the image below is my own SONY 4:3 the image was taken not to long tonight, there is visible differences in what some of the widescreens crop off the sides of the screen, I mean who sets them up! A simple way around this is to, modification the TV settings by adjust the horizontal hold and by placing a test card on the screen and adjusting it until the best results are achieved.
