Phil: Based on a Philips model I nearly bought recently, the screen is
actually 15x9, and a 16x9 picture was therefore displayed with small bars
top and bottom.. on a 'widescreen' set.
I also have a 13.5x9 LCD monitor bought a year or 2 ago .. its okay if I
use it with my ACE converter to expand the image, and crop the sides off,
but an expensive solution.

1/ Not all screens are primarily made for broadcast
2/ Earlier Japanese HD widescreen was 15x9
3/ Cinema uses a variety of formats ... and the screens may be aimed at
editors (eg Macs)

4/ A cheap domestic TV will/may use whatever cheap panel is available to
the factory.... caveat emptor (if spelt correctly)
