Some questions I have are:
1. What is the difference between the Criterion & Precision series?
2. I was thinking of going with Briliant White finish. What determines which one is the best for you?
3. Any feedback about using Carada screen with Sony VPL-HW10? Which screen?
4. Where do you purchase these screens? Best price?
The Criterion has a 3" bevelled frame, whereas the Precision has a flat 2" frame. If you have the space, you're probably best to go with a Criterion, but I just got a 118" Precision for my HW10 last week and I'm very happy with it. (if I went with a Criterion I'd have had to go with a 10% smaller image)
See here: http://www.carada.com/Projection-Screen-Comparison.aspx
I chose the brilliant white screen material as it was the most neutral I have been able to find. (I recently tested various Carada and Da-Lite samples with my i1Pro Spectrophotometerresults here
) I also went with it for the 1.4 gain as I was a little concerned about light output based on Projector Central's calculator.
My throw distance is approximately 13ft and the HW10 is almost at maximum zoom to fill the screen. I do find the image to be a bit bright for my tastes so I'm having to use the bulb in low brightness mode with a manual iris setting of 40 or so. While that may sound bad, it's actually a good thing reallyit means that when the bulb dims over time (apparently most bulbs lose around 30% brightness in the first few hundred hours) I can just open up the iris and still have a bright image. That said, I do now wish that the auto iris setting on the HW10 had some sort of range control so that I could have set the maximum to 40 so things weren't too bright as it does improve the contrast in some scenes.
I must say that there was one thing I was left a little disappointed with though. The black levels on the screen vs projecting onto a flat wall are perceptibly worse. They aren't actually
worse, but because the image is now framed, I now perceive letterboxing to have poor black levels, rather than simply not noticing it before.
E.g. projecting on to a white wall when the projector arrived:
While the walls above and below are far from black, you don't actually notice it when watchingyou only see the picture.
Projecting onto the Carada screen (note: the image isn't centredI need to get a different wall bracket as the one I have keeps drifting to the left)
The first thing I want to say is to ignore the shadow on the second image. I took that just after calibrating the screen to test something (comparing normal/wide colour space when fully calibratedhard to judge objectively as you have to change a few settings and can't just A/B it) and hadn't moved my i1Pro out of the way in case I was going to take more measurements.
But as you can see, the fact that the 2.35:1 bars aren't black is a lot more noticeable now that the image is framed by the screen and the black velvet on the walls.
The wide viewing angle of the material used also means that reflections off the side walls/ceiling have quite a big effect on contrast. (which should hopefully be eliminated once the ceiling and walls are fully covered)
None of this is specifically a problem with the Carada screen thoughit would have been the case with any screen. (but perhaps one with a narrower viewing angle would have been a better choice for my room)
As far as I know, you can only purchase Carada screens directly, but they are very reasonably priced for the quality of screen you're getting.
I had very quick responses from Carada when I emailed them, and had no problems getting one sent out to the UK. Even with the shipping costs (which were fair) the screen was competitively priced.
