I have a question. I have a Slimfit TXT2082 and when I watch a letterbox movie, I notice on the black bars that the left side is more curved that the right side. Below is an example of what it looks like. Mine is not as bad, I just exaggerated it a little bit to help point out what I'm talking about.
What should I adjust on the Service Menu so I can remove the curve on the left side?
