Large 4 way masking screens
I've decided I'd like to have 4-way masking in my planned cinema room, budget permitting.
However, I'm struggling to find any reviews / comparison or very much information at all about the various options. Here is my criteria:
1 - I'd like to be able to automate my setup such that the content playing automatically resizes the screen (via masking) not only to the correct ratio, but to a target display size. For example, I may want to watch some content at 170" 2.40:1 and other content at 135" 240:1. Or 170" 16:9 vs 155" 16:9. I am technical enough to do the programming for this, but I need the screen to be able to respond to specific instructions on the 4 panels independently.
2 - I'd like to ensure that the masking panel - specifically the one at the top, is as thin and as close to the screen as possible. My projector will be mounted ~6m back, and about 40cm above the top of the visible screen (in the worst case scenario) - and I want to minimise the dropped shadow.
3 - Size wise, the total width I have available for the screen after deducting speaker space, and including the frame, is 450cm (14.76ft) and the total available height (also including frame) is 250cm. This likely means a visible screen width of approx 410cm, and height of 205cm, I would like to maximise this.
4 - The masking panels have to be acoustically transparent
5 - Full closure would be a nice bonus.
So far I am looking at DT screens Dynamic 4, as well as Screen Research X4R3-160-2.00 and the Screen Excellence TAM-4. I believe the Director's choice can be ruled out as it's too expensive.
I am hoping someone here has experience with some of these screens to give me some feedback.
