I'm currently building our new theater room and I've got several questions before I start purchasing material.
Screen size and base material:
The screen will be 16:9, 120" 'zero-edge' PVC foam with dimming LED back-lighting. The examples I've seen in this forum look fantastic.
My current calculations place the support frame 1.5' from the screen edges. Is this distance appropriate for the LED glow to be pleasantly visible? Is 1' more practical?
I have found two sources for the screen material - 60" x 120":
- Brand unspecified PVC 6mm white @ $150, 25 minute drive.
- Komatex PVC lead-free (I won't be eating either material) 6mm white @ $116, 60 minute drive.
Are these prices competitive? Reading the forums here indicates that either brand, Sintra or Komatex, would be suitable.
Is there anything I should look for to ensure the quality of the sheet other than a smooth surface?
Basement room, no windows.
Films, gaming, 2d and 3d content (primarily 2d)
I will be viewing films without any ambient light. My wife, however, would like some ambient light so that she can point out the mess the children are making with their food and beverages. I rather enjoy the house lights coming up to a shocking popcorn disaster. The wife not so much - queue sad trombone. The LED back-light may provide enough light, but if not, a dim lamp or floor lighting may be in use.
The maximum throw will be 15'.
I will be replacing a pico that I'm using temporarily to gauge the screen size and seating.
I have not purchased the actual projector yet, nor do I have much experience with them, but I've looked at the JVC-x35 and the Epson 5020ub. I am open to recommendations on any other projector, or strong opinions against either of the two I'm currently comparing.
Using the x35 as an example, and a maximum 15' throw, the elitescreens calculator gives me 25fL, which must be with the absolute brightest mode. Eliteprojector calculator confirms this with ratings from 7-25fL. 13.8fL using low lamp. For 3D viewing, dynamic mode produces 20fL. Is that too low? Again, I don't have much experience here.
Screen paint recipe:
Which DIY screen paint formula do the experts on this forum recommend, given these somewhat flexible constraints?
