Just to add more info to this thread, here's what one of my former co-workers 
said:

"We have some Panasonic professional monitors that use
displays manufactured with an aspect ratio of 15:9 (1.67). To display
16:9 (1.78) ATSC pictures, they leave a few lines of black at the top
and bottom."


Seems to me the entire issue is about as confused as if it were government 
controlled.
