Hmm. In the second picture we're seeing the horizontal blanking bar on the right-hand side, which could indicate the whole picture is being scanned but not in perfect sync with the TV's horizontal frequency. That being the case, if he moves the picture to the right with the horizontal control, we may not see any horizontal blanking on the left-hand side? I guess in theory the horizontal blanking bar should be equal width on both right and left sides if the horizontal oscillator is in perfect sync with that of the signal it's receiving?
