While the dream of 100" displays is a nice idea, the reality remains that there hasn't been anything far beyond the tube TV for over two generations, and as we move into flat panel displays, the concept of the really big display still is daunting to many people.
Perhaps we will someday have those windows in our home from Total Recall that just put up whatever image we want with perfect clarity, but until then, we have the next best thing with front projection in our homes.
Realistically, for under $1,000 you can get a 100" screen and a HD projector which rivals $25,000 setups from just a decade ago. That's pretty darn amazing no matter how you look at it.
I've personally never been a fan of 2.35:1 CIH setups at all for the microscopic gain in quality you MAY receive compared to the cash laid out it is ridiculous to not simply ignore the nearly invisible black bars above and below the image, just as we do with plasmas and LCDs - and we will continue to do for decades to come.
Masking systems are great if you gotta have it framed perfectly, and if they made 2.35:1 (or wider) projectors natively with infinite contrast and thousands of lumens available, then it would be a great way to do everything natively with some super duper HD format which could handle it all.
Yet, I think it's silly to wish for anything more without truly acknowledging just how far we have come in less than a decade with HD technology. When, a decade ago there were people in the Washington DC area at WETA who were jumping up and down in excitement because they were able to broadcast AND receive snow in HD. Not snowfall, but when a screen goes blank and just shows 'snow' on screen. When they achieved that in HD, it was one of the first publicly broadcast HD images ever by any network that early in the HD game.
In those days people were dropping about $20,000 for a line DOUBLER to pair with their 250 lumen CRT projector ($25,000+) which required semi-annual, if not monthly maintenance to retain a best possible image.
Now, here we are about ten years later and that line doubler for $20K is outperformed by the processing in my iPod Touch. Your cheapest HD displays from Vizio have more overall capability, processing, and raw performance than $100,000 systems of a decade prior.
The $20,000 initial HD projectors to hit the market are now outclassed by sub $1,000 projectors today, and those projectors offer greater installation flexibility with a better image and brightness which CRT was never able to touch.
Is this really the answer?
Geez, if it is NOT the answer, I sure as heck can't wait to see what the next answer is! I'm pretty darn happy with the answer we've already been given, that's for sure.
