With 8' ceilings and a tight mount, I would NOT use digital keystone correction.
At 15' LENS to screen, you get an image range from 100 to 149" diagonal.

Just set the check box from THROW RANGE to DIAGONAL RANGE and then set your throw distance to 15' and you will see this.
If it is 15' to the mount, it may be more like 14.5' lens to screen which works even better.
Yes, it will work fine.

My dedicated home theater is a projector and screen combo away from completion and the $1,500.00 packages out there are intriguing. Alas, I can't figure out if digital zoom will bail me out of my HC3800 dilemma. I built a recess into my ceiling(for the mount) so the projector would be as tight to the ceiling as possible and now the 15' throw distance is locked in. I do not have room for the 124" screen the calculator says I will need to fit the image at that distance.
Does the HC3800 zoom enable it to "shrink" the image size? If so, does that negatively impact the image?
I am also concerned about the 20 - inches the calculator says will be from lens to top of image. I read another post and several replies on the keystone topic, but that one digressed into a lamp life debate/statistics 101 lecture, leaving me with no answer. I only have 8' ceilings and don't want the bottom of the image too low.
Bottom line.......will I be able to project a 106" diagonal image from 15' and tilt the projector so I can achieve ideal image placement(not too low)? From what I have read, I think I need a projector with vertical lens shift and possibly more zoom capability. But if I knew the answer, I would not have come to you all for help.
Any ideas? |

Thanks for the help.
The Lens Throw Ratio is 1.38 - 2.06 it has a 1.5:1 zoom it looks like I will have to mount it about 14 to 16ft from the screen. But it doesn't have any lens shift; if I mount it on the ceiling would the picture be on the screen or on the floor? I know the mounting is critical but will it work with the parameters I have.
The screen will be mounted above the fire place mantel that is 55" from the floor to the mantel & from the mantel to the ceiling is 90"
The paint on the walls is no longer white but a light brown. The Epson and Panasonic models are these better pj? I dont know if the Epson 8100 would work better |

Hello.
My room is 21L X 15W X 12H The room has no windows and only two doors that let in little light. I would like to mount a shelf or an PARAMOUNT wall/ceiling mount on the back wall and install a MITSUBISHI HC3800. The mount will extend 22" from the back wall but I don’t know how far down I should install the mount? The screens I think will work is a 133" X 65 X 116 or a 123"x 60 x 107
VUTEC ELEGANTE FIXED FRAME and the screen will be about 19 to 20ft from the HC3800.The screen will be mounted above the fire place mantel that is 55" from the floor to the mantel & from the mantel to the ceiling is 90".please help
THANKS. |
