Actually, (...and no offense intended....) when people come aboard and ask to do the impossible for impossibly little, it's almost always a case of their knowing a impossibly small amount of what is needed to be known.
A point in dopebohy's favor.....he came aboard to at least ask. More often than not, because of such foresight, they and their aspirations can be salvaged. But there are limits, and resolving truly difficult requests...and getting it right the first time around requires that you meet the minimum criteria in your suggestions to be able to effectively give another sage advice.
But golly...the particulars and peculiarities inherent in such cases can be daunting...and even discouraging. As such is all too often the case, I have found that referring to and sticking to known and proven formulas I myself have tried and succeeded at does the Poster (...and me...) the best service.
If dopebohy has the time and patience at this conjecture to really research....make a decision or two based on that and advice, and then wait until his PJ / Screen of choice luckily falls to within his budget....or he somehow finds quality Used equipment still in Warranty at a reduced price, , then all that would of course suit him best. If he does though....I'll be jealous.
That would be too much good luck for anyone (...then again, I hate all PowerBall winners as well...)
Personally speaking.....unless his viewing environment isn't as bad as stated, and his personal standards are lower than someone like him is apt to possess, I maintain the same stance that Jim took.
It ain't happenin' at $500.00. Leastwise not looking like much of anything.
High Contrast (Blacks that start out Gray only get "more Gray" in ambient light. The reverse is where you want to be starting out.)
Short Throw to optimize lumen output
Highest resolution possible. VGA is not acceptable..
5000 hr Bulb (4K on Eco)
A "Dark" Gray, High Contrast High Gain surface (1.0-1.2 gain)
Sub $1000.00 ? Absolutely
$500.00? End of discussion.
Except one little thing:dopebohy
mmakes a valid point....can you relate as to what part of the Entertainment Industry your involved in, and as to how the need for a Large Screen ties in?
Might not only be revealing, but some assist in solving the problem at hand.
