--- Quote ---cinema screens are acoustically transparent --- End quote --- And is why early adopters of digital projectors often found the image wasn't as good as expected when projecting onto an existing screen,pixels would disappear through the little holes in the screen that made it acoustically transparent. --- Quote ---3-10 kW in current cinemas --- End quote --- so much for modern technology being more efficient ,the old vicy 5 had a 2-2.5kw lamp that was more than bright enough for the average uk cinema |

I think people forget just how much projectors suck, and underestimate just how good typical modern LCD panels are. --- End quote --- For a long time most good cinemas have used 3 channel DLP projectors, which are capable of very high quality results on a large screen. --- End quote --- I’m well aware. They’re not even close. (LCD projection is essentially dead. With Sony having exited the cinema projector market, all cinema projectors are now DLP. Most non-cinema ones are too, although rarely as 3-chip types.) For example, do you know that cinemas do not support HDR in any way? Home theater overtook cinemas in terms of picture quality years ago. (Sound is an altogether different matter.) --- End quote --- HDR still exists, but in very limited projection rooms around the globe. I am fortunate enough to live in the same metroplex as Cinemark HQ and they have the latest releases in the technology there. My wife worked in cinema HDR projection some ten years ago and she touched (and fixed bugs!) on a number of features of cinema projection for what was back then the only movie still in production in HDR/HFR: The Hobbit trilogy. A Christie or Barco projector blows a home TV out of the water. |

The whole theater and all its materials could be painted matte black, but somehow consumers don't want that either. A screen of a "large TV" can be made nearly black, meaning it reflects very little light coming in from the front, solving this problem. --- End quote --- Precisely. |
