Thanks for your reply. Queestion, on some broadcasts (not all) do you get a very thin white line on the right hand edge of the picture. When I retun to natural mode, the screen is full. When I return to native, there is that very fine line on the right edge of the picture. Thank you.
The thin line you mention is one of the reasons displays do overscan. The line can be on a side, top or bottom of a picture. It could be sync data, it could be part of a 'frame', or several other elements. This is not a problem with your display.
