This is my first foray into the world of home cinema. I recently bought a BenQ W1070 projector together with a Duronic MPS100/169 matte white manual pull-down screen (100"). I was initially incredibly impressed with the set-up, although I soon noticed that the screen had a fair amount of rippling on its surface which was rather distracting in horizontal panning shots.
I contacted Duronic and have now received a replacement screen. The replacement does have some mild rippling as well but it's less severe than the old one and perhaps it's unrealistic of me to expect a screen of this price to be 100% flat and ripple free.
What I've noticed on the replacement, however, is a sort of mild "grain" effect when the image is bright, almost a bit like sandpaper. It's quite hard to describe but it's almost as if you can see the screen when there is a bright image, especially one of uniform colour such as shots of the sky. When I first spotted it my heart sank as I thought there was some form of defect in one part of the screen, but I soon realised that the location of the "grain" depended on my position relative to the screen, and that any area of the screen can show up the grain if I position myself in the right place. If I move right up to the screen or view it from the side it disappears completely. I have tried shining a torch at the screen and that shows it up too.
What I can't understand is why I should notice it now on this screen and not the predecessor, when the two screens are the same model and therefore ought to be identical. Does anyone have any idea what might be causing it? I only put the new screen up yesterday - is there any chance it's something to do with the fact that it's a new screen and the effect will wear off, in the same way that many new items appear "shiny" when new? I still have the old screen as the courier hasn't collected it yet and when comparing the two they do look very similar, although when shining a torch on that one it doesn't quite exhibit the same grain effect as the new screen (or at least it's less noticeable).
It is only rather mild, and it's probably the kind of thing that wouldn't bother some people (in fact my Dad didn't even know what I was talking about when I pointed it out) but it is a little bit distracting once you know it's there.
