Small black strip at top of screen
On a few 1080i channels (but not all) the picture does not fill the entire screen... there is approximately 1/2 inch of black only at the top. This occurs on transmissions both from Spectrum cable box and OTA antenna. At first, I thought it was just part of the bezel, but on closer inspection, it clearly is noticeable.
The picture aspect ratio is set to "Normal".
Is this a normal bug in upscaling, or is there some adjustment that needs to be made? I checked the manual, but there is nothing on this issue.
