Hmm I noticed on my tv, on the very right edge I have a faint green vertical line from top to bottom, about a 1 pixel in width id guess? I changed the format to 4:3 but instead of the faint line being on the edge of the screen, its on the right edge of the 4:3 picture. Cant notice it when using the tv, only if I'm 2 inches away from my screen staring at it. Not really an issue but still puzzles me why? No matter what ratio I use, there's always a faint green line at the edge of the picture. The line still shows other colors its just more green dominant?
