The price of screens is quite incredible. They can be incredibly expensive. To go with a JVC DLA-HD100 we've bought a Screen Research 92inch screen. It's electric, fit's inside the ceiling and is accoustically transparent. It cost. Wait for it. £3,500 and that's with a thumping discount.
These things are horrifically expensive, if you go for the top performing material, a large screen and a flush fitting design. It's cheaper if you can install a fixed screen, and not need an accoustically transparent model.
I'd be fascinated to see What Hi-Fi compare the products, but remember, they are suited to different environments, ie. total darkness, vs. some light intrusion. Grey vs. White. Transparent vs. Not Accoustically Transparent. Electric vs. Manual, Fixed vs. Rolled Up. Level of Light Reflectivity.
So there are sooooo many variables. It's a difficult area to do a piece on. Because it's almost an art in itself. What is shocking, is the price. But you pay for what you get. Would you want Monet to paint on recycled paper? Quite. The JVC is the artist, the Screen Research is, in this case, the canvas. It's installing this Summer. I'll let you know how it goes.
