Room - 13' x 21', viewing on 13' wall, white walls & ceiling with 2 x small (24" x 18") ceiling height windows on viewing wall, behind pull down projector screen, 8' ceiling
Screen - Da-Lite Model B, 106" (maybe larger in future) 2.4 gain, High Contrast, High Gain, pull down, center of screen is 62" from floor
Seating - Dark, 10' wide couch, viewing height 42", 14' back from screen, one end of couch against the wall, 3' isle at other end
Projector - Epson 5020
Mount - 15' back from screen, on floor standing shelf behind seating, height adjustable
- Lens zoom - Which way is which? Is "more zoom" bigger picture or smaller picture? Is "zoomed out" all the way, the biggest or smallest picture the lens is capable of at a specific distance?
- Lens zoom - Is less, more or centered of zoom best? Is the answer projector/lens specific (Epson 5020)? With my 15' distance, on 106" screen, I believe I will be near center of zoom range.
- Lens offset - Does anyone know if the Epson 5020 "default/neutral" lens offset is centered, bottom of the projector up, or bottom of the projector down, etc? It's best to use it at the default/neutral, right (please confirm)?
- Projector positioning - With the retro-reflective Da-Lite HCHP screen, what would be the optimum projector height? Consider the retro-reflective nature of the screen and the desired minimal lens offset. Center of the lens is 3.3" from the bottom of the projector. The shelf the projector sits on can be adjusted from 48" - 60". I also have the option to move the projector to a wall mounted shelf at about 20' for the screen. I cannot move the projector any higher, due to ceiling light & fan fixture.
Thanks in advance to anyone who can take a look at this & provide feedback.
