At the point in setup of room, where I need to place screen on wall and mount projector to ceiling. Have the projector calculator thing here in the forums, but am still a little confused. Okay here's my setup, room is 11'W X 25'L. have a air duct that runs down the left side of the room the entire length, so have decided to position everything to the right side of the room. that leaves me with about 85.5" width and the ceilinng height is 93.5" for screen placement. I have a 96" screen. My issue is that when using the calculator it kinda appears as though it's setting me up to have the screen mounted about 28" from the floor. Well that's not what I want to do. I'd like to mount my screen about 10" to 12" from ceiling [so everyone can see] and figure from the screen where the projector should be mounted. I'll take another crack at trying to use that calculator, but if someone has some more simpler comments to use as a guide, I'd appreciate it. TIA!!!

The HD3000 has no lens shift which is clearly spelled out in the review.

So, if you have a 96" diagonal screen, and mount the projector flush with the ceiling (as possible) then the center of the lens is about 4" from the ceiling and the top edge of the projected image would be 17" below that - so about 20" below the top of your ceiling.

That's 93.5" - 20" - 49" screen height = 24.5" above the floor.

Your math is wrong - it is lower than what you are reading, and this is why this site exists. To help people make informed decisions about what they intend to buy before they buy something which is not appropriate for their room and viewing conditions.

What options do you have?

Well, you CAN tilt the projector upwards to get the screen where you want it to be. This requires you to use digital keystone correction and will reduce the overall resolution and brightness potential of the projector, but is the only option available with this projector.

Generally speaking, in your situation, I would recommend a projector like the Panasonic AX200U or the Epson 720 which both offer lens shift and allow you to put the projector almost anywhere you want in relation to the screen on the wall.

he probably didn't figure the 4 inch to the lense...

also don't worry about keystone much...I've been using it for a long time and it doesn't bother me a bit. Still looks wonderful.

Yeah I know I didn't probably do as much detailed research as needed, I purchased this equipment approximately 12 - 15 months ago at a home theater extreme warehouse blowout sale for next to nothing, so I need to make the best of what I've got for now. But one question I still have is what's the distance from the projector to the screen? Thanks!

Per the projection calculator...

http://www.projectorcentral.com/Mitsubishi-HC3000U-projection-calculator-pro.htm

With a 96" diagonal 16:9 screen you should have the lens from 11'5" to 13'10" from the screen. I would shoot for about 12 1/2 feet from screen to lens... That will give you some fudge factor.
