I reported in another thread that my M2500 screen had a noticeable crease, about 8" in length, plus what look like bicycle tire tread marks across the screen at various heights (my wife described these as looking like the quilt pattern found on some brands of toilet paper.)
Also, there were several vertical bands and one 8' wide line across the middle. Only the 8" crease is visible in natural light--all of the other "patterns" can be sen only when a bright white light shines on them.
I borrowed a Dreamvison dlp projector (600 ANSI lumens) and watched hours of movies.
The horizontal line showed itself only once on an all blue screen. The vertical streaks (at regular intervals which seem to follow the rolled up on the tube in shipping pattern) were only evident a few times during very bright scenes and only momentarily. The crease showed itself whenever I looked for it.
What was remarkable was that I started my viewing during the day--no sun but fairly bright in my room, which has an entire wall of picture windows, and a spiral staircase that lets in light from upstairs as well. The picture was as good as most of the rptv's I've seen, even brighter than some. I could enjoy daytime viewing without any blackout curtains.
At dusk, the picture was great, and we put the overhead lights on with just a little wash out on the screen. It was still very enjoyable to watch. Amd others could read in the room at the same time.
At total dark, the picture was, at times, too bright. A quick adjustment of the brightness and contrast (turning each down 5 clicks) resolved that problem. I had been cautioned that the bright Sony 10HT I am getting would not mate well with this high gain screen. The Sony is 25% brighter than the Dreamvision. But I suspect that any overly bright images could be adjusted through the brightness and contrast controls.
I plan to exchange this screen (with the crease) for another M2500.
I could easily live waith the vertical streaking, although I hope the replacement screen will be better. And the ability to really enjoy the projector for daytime viewing with lots of ambient light is very important to me.
When I visited my friend, we could not watch during the day on his Vutec 1.3 gain screen. Even after taping black plastic over most of the windows, the image was still very washed out. The difference between there and here must be the M2500 screen's increased gain.
