A few brief impressions. Just had RS 56 (X75) installed in theater room. Going from RS -35.
Changed from 110" 16:9 Carada BW to 140" 2.40:1 Carada BW Masquarade system. Basically just wider for scope films, same height. So far very impressive. Chad B. to calibrate Tuesday, (I know, too soon), just can't wait. My original plan was to use old projector with anamorphic lens system, but after seeing a demo of the concept on a Sony 95 (I think) I decided to go this route. Chad recommended a new projector based on what he knows of my taste and need for perfection, or as close as I can afford.
Overall brightness has increased, dramatically, to my untrained eye. In low lamp mode the thing puts out plenty of light, I had just replaced lamp on RS-35 and the difference is noticeable. Sharpness is tough to gauge due to brightness increase. Looks better to me after adjusting picture settings in User 1 without NR, and 4K to Film as many have suggested. Wow! Spent Saturday going through the usual discs that I am familiar and already it looks better. Hard to compare when blown up to 2.40:1, but for me the overall impression is staggering from my seat at about 13 ft. Away.
The singlr greatest asset of this unit is its fantastic black level. My old projector was state of the art at $10,000; 3 years ago. Now, however things have gotten darker and brighter, at the same time. Full field black is darker, and as a result, contrast is noticably greater. Life without black bars is heaven. Star Wars (please Disney, remaster them in 4K with original footage now that you own Lucasfilm) looks as close to my theatrical experience as I have yet witnessed. I do not notice drop in light output when zooming. Once your eyes adjust to the size, the effect is what I have always aspired; large film like picture with the resolution to pull it off at home. JVC glasses don't seem to want to work, lucky I bought some Panasonics for $30. 3D initially was, frankly, awful. Took me a bit to figure out that I had to change to separate picture settings. Still not as impressed as I'd hoped to be. After Chad takes care of it, I'll report back. I only watched a bit of Promethius and found it less than I'd hoped. After that, however, tried Avatar, and things got Much better. Not sure why. I will reasses later. The point is that 2D is the reason to have this great projector. Once calibrated I will give more detailed thoughts, but so far, very happy. My theater room is 21' by 16', with black ceiling, walls and no light; so take that into consideration. If you have the area for it, JVC makes a great product. Someday, when 4K is mainstream, then more options at this price point may exist, but
