Continuing SI Pure White discussion
I hate to continue to drag this old thread on, but the recent posts are right in my query zone. I just installed a new JVC RS600 projector. I've had a very good 8" CRT shooting a 90" diagonal 16:9 Draper M1300 motorized screen for many years. I moved during those years and had room in my new AV cabinetry for a larger screen, but burn in lines on CRT tubes prevented switching. With that constriction lifted, I want to fit all the screen I can. With Stewart, the max I can fit is 100" diagonal. The length of the weight rod is my limiting factor. If I went with Draper again I could fit 102". But, my older Draper screen has picked up visible horizontal lines from the roller mechanism and is also not opaque. I have a daytime 80" LCD right behind it, which I am sure is backlighting the screen and degrading contrast to some degree. I hear the new Draper material is basically the same. With SI I can fit a 106" screen. That is a lot more surface, making me lean toward them even though I am a bit leery of their excess marketing hype and a lack of any real data on their screens, nor ISF certifications and so on. So is their any reason I should avoid the SI Pure White relative to Stewart or other alternatives?
BTW, I have poor light control in the room, which is why I have the daytime LCD. I even have reflection and glare problems with it from the large north facing windows on the wall behind the projector (opposite end from screen). So we have gotten used to using the projector only when it is dark outside. Room itself fairly dark otherwise. Darker wall and ceiling paint and ceiling is tall cathedral. Floor fairly dark too. Viewing area is around 14' wide and ranges from 8-16' back from screen depending on where you sit. Projector throw is short side, around 1.4ish.
On another note, I took home some samples of ALR SI materials. It is hard to say if I got a good feel using these smaller samples, but neither BD or neither Slate or even Pure Grey did it for me. Slate 1.2 looked like it was the best of the bunch, but for the gains made in ambient contrast it knocked off quite a bit of brightness and visual punch. And it still didn't solve the daytime problem, it only improved it. And it looked like it would degrade night time movie viewing in lost bright levels and viewing angle drop off. Am I selling the ALR materials short?
