82 inces
Well this may be the first / biggest of its size but really the specs are not that good.
First:
6" thick is not slim. Look at the latese samsung LED TV's they are 1". And why build it LCD in the age of Plasma and LED.
Second:
Standard HD resolution on a 80" TV looks fine from 8 feet away, but standing there touching it, you will need much more resolution. My 23" monitor with HD resolution (1920X1080) is barrly acceptable.
Well at least it is fast and reliable.
