Long time lurker, first time poster. I'm building a projector screen for my existing projector setup. I'm running an Optoma HD20, soon to be upgraded to an Optoma HD25e. My current projector is a boring old drop down one.
Anyways, onto the plans! Ordinarily, I would wait until I'm nearly complete, or complete before posting like this, but I did a lot of research on the topic and thought someone might want to chime in with advice, and I would be remiss if I didn't listen to it!!
I don't plan on actually building for another few weeks still, and these plans are subject to change.
This is the top view:
The vertical height will be 55.429" total, and the horizontal screen measurement will be 95.873"
The horizontal dimension in the image there (94.9102) is the exact flat width it would take to make the curved face exactly 95.9102" wide. 95.9102:55.429 is a 16:9 screen that would measure at 110" diagonally.
and a gif of the initial design assembly:
I can say that right off the bat in the shower this morning I had a stroke of inspiration. I didn't know how I was going to mount it, but this morning I saw my bathroom above-the-toilet cabinet flush mounted to the wall, and remembered I used a french cleat! It'll ensure a level screen, very strong, and very easy to put up and remove if I need to change anything!!
This is my second design, my first design was actually using a masonite screen, and glueing the canvas on top to create a completely "edgeless" projection. I think I'm going to go back to that design.
Does anyone have any thoughts on painted screen vs. canvas screen? There's a lot of ambient light, so I need a white screen, preferably a 1.0 gain though.
It didn't occur to me until a friend mentioned it but painting the masonite might be even easier, slightly less weight than masonite+canvas, and it's guaranteed to never wrinkle or ripple. Not to mention it might turn out cheaper. My only fear is I won't get the same quality of finish and even image.
With the advent of the french cleat, the design has to change a little bit already, but not a big deal. I haven't figured out how I'm going to do diagonal reinforcement without interfering with the cleat, I might do the cleat with a gap in the middle and use that. I'll play with it some and see. If I put masonite on the front though, I'm not sure I need diagonals at all, they were there to ensure no flexing or bending, but with masonite....there won't be a worry of that.
