Well long story short, the room was designed to have an overhead projector (did the basement reno in 2005). The room was also designed to be setup in one of two ways, long or short axis. We decided to go with the short axis and at the time, no projector could throw at such a short distance. Also, that max. wall space available for viewing is literally about 75". No projector at that time was throwing anything under 85". Hence, we've stuck with the tv until plasma and then LCD/LED came along. I saw how large format plasma and LED tvs were getting and becoming VERY cost effective, so rather than have an overly hot, somewhat noise adding overhead projector sitting above the seating area, AND having to rearrange the room to the long axis (based on the ceiling connector locations), i said screw it. We'll wait for plasma or LED to come about a bit and decrease in price and 70"+ screens were doing just that UNTIL OLED started up.
It became clear that plasmas were going to die off (and not sure they had formats above 65" or if they did they were stupid expensive) and by this point i had experienced the downsides to LED so...the long wait for OLED began.
And here we are.
Of course with the cost of a 75" OLED presently, one could get a very good quality projector and screen, the other issues mentioned still exist so again, for the extra cost and the likelihood that this TV will last me another 20 years, i'll probably stick with the plan for OLED later this year.
