While it may not help you much, at home we have a big screen HDTV (doesn't matter except it's big) and the problem I see is that 1080p at these dimensions is going to have some complaining about "is that all?"

The reason why might be the display's DPI is dropping fast as the screen size goes up.

My kid's 16 inch laptop is 1080p and has razor sharp graphics. Put that on the big screen and the same pixels are there but blown up and you might say it's fuzzy.
