Yes. A thinner frame surrounding the display means a larger TV can fit in the same space. That was the motivation for trying a 50" TV. I originally thought that I would be limited to a much smaller unit. Of course the width of the frame is not included in the size specification of a North American TV. In fact, many LCDs and Plasmas actually measure 0.5" less owing to the old standard that compensated for CRT glass curvature and still allows manufacturers to slightly inflate their specifications.
The wide aspect ratio is interesting too. Increasing a 16:9 LCD by 10" raises the external height by less than 4" and sometimes more when a manufacturer uses a thinner 'chin' than before..
I must admit: The area behind the screen would be nice to use. I am not sure I can find hinge that could support 40 lbs, be completely silent while travelling and allow minimum clearance between the top of the display and the ceiling. I will keep looking.
As it is, I still have some road tests to complete to make sure this new TV doesn't move. Gassers are loud enough without a TV adding to the chorus.
