I adjusted the screen setting from the cable box converter.
The converter defaulted to ZOOM mode when initiated. One small click and thi pic was normal. Problem solved! -- jmb
I just purchased the above unit and am quite satisfied with it except for one thing. The picture extends beyond the screen boundary on HD channels. I have tried adjusting the screen size on the options menu from a +10 down to a -10 for both horizontal and vertical, but these settings seem to have no effect. For movies with sub-titles, bottom line of a 2 line phrase is cut off! Am I missing something here on the adjustment? The manual is not very helpful.
