    I'm upgrading our home studio to 5.1 and in the process making it a home cinema room. It's all new and rather exciting, and I'm afraid I've got some rather newbie questions.... I've got a rather specific set of requirements for the screen, and I was wondering if anyone can tell me if this is possible or not: I'm after a motorised acousticaly transparent screen... do such things exist? I've read the thread elsewhere in this forum about a new acousticaly transparent screen, but there doesn't seem to be any mention of if it's motorsised....

    Also, how acousticaly transparent are they really? We have a properly lined up 5.1 monitoring setup for mixing and tracking, and it's really important that the screen be trully transparent, or at least come with detailed notes on any eq that might need to be inserted to make the response flat...

    One more question... I vaguely remember someone saying once that perforated screens cause major problems for video projectors - something about the pixels lineing up with the holes and getting interferance patterns or something? Can anyone enlighten me?

    Phew... lots of questions! ;-) Thanks guys (and girls)...

    Take a look at Screen Research.

    http://www.screenresearch.com

    I have not seen them myself, but have heard some good reports from others.

    They are not affected by the moire effect, since they have no actual holes in the screen.

    just found it... Le Wing looks pretty cool, but we have a hard core active monitoring rig that we want to do justice to so we don't need the speakers! Still no sign of the cost though...

    Just to give you an idea, in europe a Screen Research 110 inch wide electric roll up with black backing is 6000 euros.

    From What I have heard, the screen is worth it.

    Stewart screens, in all their flavours, are available microperforarted. Stewart screens come with their own EQ box but folk like Genelec can give you the eq settings to use if you are using their monitoring speakers. I'd also expect STEWART can tell you what EQ is required.

    Screen Research should be able to give you the same information. Both screens are likely to cost......

    It's true that with micro-perf screens and with many woven screen fabrics you need to be careful in your choice of projector as a moire pattern can show up on screen due. This is a diffraction pattern caused by weave/holes and gaps between pixels lining up in an in-opportune way.

    Have fun,

    I have recently purchased (by coincedence) both of the aforementioned screens: Steward Microperforated Firehawk and Screen Rsearch Clearpix2 (both 123" diagonal fixed frame 16:9).

    So far I have only installed Clearpix2 and very pleased with it. The screen, as expected, does appear not to have any noticable effect on sound. I had increased the volume on the front three speakers by 1dB to compensate.

    Picture wise, in the light controlled environment and with non-reflective background, it perform as well as my previous matte-white gain 1 material (and I was happy with it).

    I haven't yet had time to install Stewart, but I think its acoustic performace would stragle to match Screen Reseach's.

    Very interesting.... what do you think of the look of the SR screen? I had a sample of standard screen with holes in it material, and the holes were VERY obvious. If you don't mind me asking, how much was the screen research one?

    Ta!

    The structure of the Clearpix2 material is visible only if I come very close to it. There are no wholes as in Stewart micro-perforated but the material is made of evenly woven threads.

    From abot 0.5m onwatrds the material looks completely smooth.

    Hi Branxx,

    I was just wondering if you have been able to make the comparison between the two screens yet.

    horneydragon,

    Thanks for the info, but I am really between these two screens. I realy do not want to compromise the sound and image quality.

    Maybe I am looking for the Holy Grail. Or is it Holy screen :)

    You are right about that. I will give Vutec a shot.

    Thanks,

    Interesting thread, and well timed from my perspective!

    I have just bought a Digital Projection iVision HD (HD2, 720dpi), and am looking to buy a Da-Lite Micro perf Cinema Vision Screen (Contour Electrol). Can anyone (or Liam!) develop on what Liam had mentioned about choosing the right projector, and whether this would not a non-starter for my projector?

    Is this a resolution things (i.e.tighter pixel resolution result in this being less of a problem?). Basically, is there any reason not to do this? The projector is set, and I have been reccomended the Da-Lite, and been impressed by them so far. I would appreciate the valuable objective advice this forums always gives.

    Oh, in my set up, only the centre speaker will be behind the screen, and at the very bottom of the image.

    Cheers,

    Paul

    As far as I know, the only concern with a microperf screen is moire. Current thinking is that if it is less than 100 inchs wide you have a high probability of having this problem.

    This is not the case with woven screens.
